Zinc plating is suitable for outdoor use in moderate-to-high corrosive environments, but stainless steel may be a more reliable choice due to its superior corrosion resistance. When choosing between stainless steel screws and galvanized zinc screws, consider the pros and cons of each type.
Zinc is an extremely tough protector, but it can wear down, creating a weak spot through which the original steel is exposed to the elements. Some of the best materials for screws for outdoor use include zinc wood screws, which are more prone to rust unless coated or galvanized. Stainless steel screws are rust-resistant throughout the entire screw, not just on the surface. Zinc’s oxidation reaction or corrosion process is significantly slower, thus it will last longer. However, metal screws will rust over time if exposed to air and moisture, and zinc screws are not an exception.
Lag screws, or lag bolts, are heavy-duty fasteners best used when attaching framing components such as posts, joists, and headers. They come in various diameters and lengths and can be used in various environments. The better grades of stainless, like 316SS, can hold up indefinitely in most environments. Galvanized screws have a zinc coating, making them resistant to corrosion. They are especially suitable for use on treated lumber, as the chemicals in treated lumber can cause corrosion.
Hot-dipped galvanizing (applying a thick layer of zinc to the screw or bolt) is the best defense against copper corrosion. Stainless steel is the most durable option when it comes to different types of nuts, offering enhanced corrosion resistance. Its resilience to rust is due to the chemical composition of the steel.
In conclusion, selecting the right weatherproof screws for your project depends on factors such as the environment, the type of screws, and the desired durability.

What is the best metal for outdoor screws?
Stainless steel 316, also referred to as marine-grade fasteners, is the optimal selection for humid climates due to its resistance to corrosion and pitting from chlorides, rendering it particularly well-suited for coastal regions.
What type of screw is best for outdoor use?
Outdoor screw options include deck screws, coated screws, silicon bronze and stainless steel, hot-dipped galvanized fasteners, Phillips head or star drive screws, and hot dip nails. Deck screws and coated screws are popular due to their rust resistance and corrosion protection. Silicon bronze and stainless steel are excellent choices for pressure-treated wood. Hot-dipped galvanized fasteners offer superior rust resistance, but they are typically only available for nails. Phillips head or star drive screws are strong enough for pressure-treated lumber.
What kind of screws won’t rust outside?
Stainless steel screws are a popular choice for rust-resistant fasteners due to their unique properties that allow them to withstand harsh outdoor elements. These screws are solid stainless, unlike other options that have a stainless coating on top of a different material. There are two types of stainless steel screws: 410 stainless (which includes some carbon steel for strength and magnetic properties) and 18-8 (which includes all 300 series of stainless and is non-magnetic). These screws are used in many outdoor projects due to their rust-proof properties and the versatility they can accommodate in various jobs.
Is zinc or stainless steel more rust resistant?
Stainless steel is a more durable and resistant material than zinc alloys, which are cheaper but more susceptible to rust when exposed to moisture. Stainless steel is used in most applications requiring water exposure and is also used in surgical instruments due to its stain resistance. The cost of manufacturing stainless steel is higher due to its Choronuim origin, making it a more cost-effective option for many industries.
Will zinc rust outside?
Zinc galvanized coatings are more corrosion resistant than bare iron or steel. They corrode at a rate 1/30 of that for steel and rust at different rates depending on their environment. Common environments for galvanized steel include indoor and outdoor environments, storing chemicals, fresh water, sea water, soils, concrete, treated wood, or extreme temperatures. The performance of galvanized steel depends on the environment and the galvanization process.
Hot-dipped galvanizing creates a zinc barrier and sacrificial cathodic protection to prevent steel corrosion. The zinc is protected by a patina layer, formed by zinc corrosion and rust products. Zinc oxide and hydroxide are the first products, followed by zinc carbonate, a stable film that adheres to the zinc surface and corrodes slowly. This layer turns the zinc coating a dull grey color.
Is zinc good for outdoor use?
Galvanised steel is a durable and corrosion-resistant material suitable for various applications, including roofing, gutters, fences, and sheds. Its zinc coating acts as a protective barrier, protecting the steel underneath from rust for decades. Galvanised steel can withstand harsh outdoor conditions, such as heavy winds and hail, without warping or breaking. Its low maintenance requires only occasional cleaning with soap and water, resulting in significant time and cost savings over the years. Overall, galvanised steel is an excellent choice for structures requiring enduring weather conditions.
What 2 types of screws are used for outside or exterior use?
Outdoor screws are essential for projects that require durability and resistance to corrosion. Stainless steel screws are the most suitable type, as ordinary steel is not as resistant to corrosion. Silicon bronze screws, commonly used in the marine industry, are also suitable for outdoor use. Decking screws are another option.
Choosing the right type of outdoor screws is crucial for avoiding potential issues later on. Stainless steel screws are more expensive but are necessary for outdoor projects, as they are more resistant to corrosion. Other types of screws, such as decking screws, are also suitable for outdoor use.
In summary, choosing the right type of outdoor screws is essential for ensuring the longevity and longevity of your project.
Are zinc screws weather resistant?
Zinc-coated screws are resistant to corrosion and suitable for outdoor use. However, they may corrode over time, particularly in environments with high moisture or salt exposure.

Can zinc screws be outside?
Zinc-plated steel fasteners are a popular choice for corrosion resistance, suitable for outdoor and industrial applications. However, they are not suitable for marine or high humidity environments. Zinc-plated bolts and nuts are cheaper than stainless steel nuts and offer acceptable strength and corrosion resistance for most non-specialty applications. Galvanized nuts, coated in a thicker layer of zinc, are also corrosion-resistant but not compatible with bolts made from other materials.
These nuts are the most durable material but not compatible with bolts made from other materials due to slightly different dimensions between galvanized steel and stainless steel nuts. Both zinc-plated and galvanized nuts offer a variety of applications and are worth considering for their durability and corrosion resistance.
Are zinc screws waterproof?

I run Phillips as a diyer because that’s what I started with and I have multiple 5 pound boxes of Phillips head screws. Now my dad spent years as a contractor and went from Phillips to square and finally torx. Once a year I spend a week working around his house doing as many things as I can for my 79 year old parents. First thing I do is fill a pocket with driver bits because I will need them all, I spend more time switching bits then I do anything else. Last summer I replaced a PVC outdoor water line and needed phillips, square 2 and 3, and 2 sizes of torx to remove the 5 clamps holding the pipe to a wood wall. When I put the new line up I used Phillips from my stash.
I think this is more revisionist history. I worked on a number of projects in the late 1990’s with the then President of Robertson Whitehouse in Milton. He indicated that the reason the Phillips drive became dominant was that the automobile manufacturers could not deal with the necessity of having to line up Robertsons precisely while on the assembly line. The ability to engage the drive on a slight angle (the name of this escapes me) was key for automated assembly. Cam out was a problem they simply lived with to have the ease of alignment.
As someone who sells fasteners I will tell you that all fasteners have a purpose. I can’t tell you how often I hear people complaining about snapping heads off square and torx because they refuse to pre-drill. If you are installing the part correctly square and torx are great but they can easily be overtorqued and cause headaches. Also from an expense perspective Phillips will be cheaper and if it is a one time use fastener Phillips is more than likely good enough. Generally I try to recommend Phillips for general work. Robertson for stainless deck screws and torx for hardwood projects and projects where the fastener will be visible upon completion.
Hate screws that don’t cam out like they are supposed to. Installed lots of kitchen cabinets and when the screws don’t cam out like they should, driving them flush with the surface is a real pain. I loved it when the world was a # 2 Philips. The good old days, and you could buy them by the # for cheap. Best deal ever.
I use all 3, torx when older seems the easiest to get out. Roberson I never have a problem installing, its only after 4 to 5 years they seem to cam out hard when removing, phillips seem to strip out completely after 4 to 5 years. Going in and holding they all seem to be equal with philips camming out a bit more than the others and the bits wearing out faster. I think the biggest difference in all of them is the bits you buy. the quality of the bits. To me each has a specific purpose where I prefer to employ them and will not get rid of any of the three. I will not even mention the other as it is useless in the best of circumstances.
Torx and square drive are are way superior where higher torque is required. Phillips and the European pozi drive are much of a muchness, with the Phillips tending to cam out and the pozi drive just snapping off. For electrical work, the combination screws, with a straight slot, allow you to remove the screw without having to resort to an impact screw driver. Electrical equipment is not rated for this. I use an old, low torque driver for Phillips fasteners, and have a good supply of bits and fasteners available so I can toss them whenever they twist, snap or otherwise fail. The square drive would solve most of these problems, but are not so easily available in Australia .
I think the biggest problem with Philips head screws is matching the driver size to the screw. With the square and the 6 point, it’s easy to tell if you have the right size driver. With Philips, it’s not that easy. At least for me it isn’t. I find myself one or 2 sizes off. It seems to drive okay, until the end when the pressure gets increased. Then it’s slip and strip the head. For this reason alone, I prefer to use either of the other 2.
I watched a documentary once about P.L. Robertson. Apparently he had a disagreement with Henry Ford about licensing his design. Ford wanted to use the design but Robertson wanted to keep all his manufacturing in-house and Ford wanted to make the fasteners himself and pay Robertson a loyalty. Both were headstrong stubborn men so could not come to an agreement. Therefore Ford made a deal with Philips instead. And this apparently greatly increased the reach and market share of the Philips head. And relegated Robertsons to a niche market.
I definitely think Torx and Robertson are better, but we don’t need to make up excuses for Phillips just because they are more common. If we are going to change, let’s ALL agree to change. But I don’t think that’s going to ever happen. It’s nice going to a job and being pretty confident every screw you encounter will be same type.
They have a new (or not so new) invention called a torque adjustment that comes on most cordless drills, these days. You can adjust it for low torque and experiment first with the hole size you’re using, gradually increasing the torque until it drives the screw all the way in. I can usually tell by the amount of back pressure, or kickback, when there’s a risk of screw snappage (Is that a word? It is now.) One clue as to when a hole is too small is that when you’re driving the screw, it squeaks. You can also check the torque required to drive the screw in that size hole with a manual screwdriver before starting with the cordless drill or at any point during the driving process. If you do these things, you should have no problem with breaking screws unless you just get one that’s defective. You may have to enlarge the hole a bit, but in some soft woods, I’ve found, it’s better to drill them a little small. They don’t strip out or pull out as much that way.
Those square fasteners are even worse than Phillips screws. Never had so many problems with a screw coming off of the socket. Torx are easily the best to use. I built some shelving that used some 300+ screws and I switched to torx from Phillips after the first box of screws. Not only were the Phillips stripping out, but this was causing the bits I was using to break. No problem after switching to torx.
My fundamental problem with torx is that you can easily use the wrong size drive on it. It just seems like a complete failure of design to have the drive sizes spaced closely enough that more than one driver will fit. At work I have to take a lot of different things apart all with different fasteners and torx is the most maddening one, if I find what I think is the right size I have to check that the next size up also. So sure, if you buy a box of screws and use the included drive, or are consistently using the same ones over and over in a construction or manufacturing setting I guess torx is fine. But from an operator or maintenance point of view, torx is awful.
I hate Phillips screws, striped one to many heads while trying to remove them. We should all be able to agree that flat head screws are worthless. I use to be in the square drive camp, but i have since found torx to be the most reliable of all the many drives I have tried. If i can get a torx in, without breaking off the head, then I can get it back out… You didn’t even mention any of the proprietary specialty drives, like the triangle drive, the Y drive, or the 2 pin.
