What Kind Of External Wall Tapcon Screw Should I Use?

The Tapcon® concrete screw with the Climaseal® coating offers excellent rust resistance for both indoor and outdoor applications. Available in two diameters, 3/16″ and 1/4″, these screws require a 5/32″ hole in the concrete for optimal performance. They are designed with Advanced Threadform Technology ™, which cuts threads into all masonry materials, including concrete, block, and brick.

To install a Tapcon anchor, drill a hole in the concrete and choose the correct screw type and size. Proper installation, including choosing the correct screw type and size, pre-drilling holes, and controlling torque, is crucial for successful use. Tapcon screws are made from hardened steel and coated with a zinc finish, providing superior precision and unparalleled performance.

These concrete screw anchors deliver 30 less torque and 20 more holding power, while drill bits enable precise hole creation at maximum power. They are best suited for light to medium duty fastening purposes and come in standard 3/16″ and 1/4″ diameters, as well as large diameter sizes of 3/8″, 1/2″, 5/8″, and 1/8″.

Tapcon Stainless Screw Sets are ideal wall mount screws for securing Suspenz Storage Racks onto concrete walls. These screws are designed to be just stiff enough to provide the ultimate in corrosion, rust, stain, and temperature resistance. The 410 Stainless Steel Tapcon is the most universal screw for almost any application.

How deep should a Tapcon go into concrete?

To insert a Tapcon screw into a concrete hole, drill the hole to the correct depth using a depth gauge or tape. The minimum depth for embedment is 1 inch, with a maximum of 1-3/4 inch. The hole should allow a minimum space at the bottom of the hole of 1/2 inch. Before inserting the screw, clean the hole of dust and debris using a wire brush and vacuum. Compressed air can be used to clear the hole, but it may not be suitable for all situations.

Insert the screw through the fixture and into the predrilled hole using a rotation drill, driving slowly with minimal pressure. For flat head Phillips, a 2 driver is needed for the 3/16-inch screw and a 3 driver for the 1/4-inch screw. The 3/16″ hex head is installed with a 1/4-inch hex driver, and the 1/4-inch uses a 5/16″ driver.

Why are tapcon screws blue?

Tapcons are rust-resistant concrete screws coated with a blue rust-resistant material called Climaseal®. They come in two diameters – 3/16″ and 1/4″, with different lengths and head styles. The hole diameter must be the correct dimensions and meet certain tolerances, and a carbide bit that meets ANSI standards must be used in a hammer drill. The minimum embedment is 1″ into the masonry material, while the maximum embedment is 1-3/4″.

The length of tapcons to use is determined by adding the thickness of the material being fastened to the minimum embedment, which calculates the shortest screw to use. The length of tapcons to use is determined by adding the thickness of the material being fastened to the maximum embedment of 1-3/4″.

To install tapcons, use a hammer drill with the correct diameter ANSI standard bit, drill a hole in the base material a minimum of 1/2″ deeper than the Tapcon will penetrate the masonry material, clean the hole with a wire brush, compressed air, or vacuum, insert Tapcons into the hole, and turn clockwise using a wrench, screwdriver, or drill until the head of the tapcon is tight against the surface of the material being fastened. Ensure that the Tapcons are not over torqued, as this may strip the threads in the masonry or shear the Tapcon off.

Do I need to pre-drill for tapcon screws?

In order to create a high-quality hole in a concrete brick or black hole into the base material, it is necessary to use a hammer drill.

Can I install tapcon without a hammer drill?

The hole diameter and depth of a Tapcon® concrete screw are crucial factors in their installation. The tolerance between the hole diameter and the Tapcon® screw used is very tight, and any variations can affect holding values. Each diameter of concrete screw has a specific diameter carbide drill bit that must be used for installation. The hole must be drilled using a hammer drill with a carbide tipped bit meeting ANSI standards to ensure the hole diameter meets the Tapcon® requirements.

The depth of the hole is also critical. The hole must be drilled 1/2″ deeper than the screw will penetrate, allowing for an area for dust to fall without impacting installation. If enough space is not created during the drilling process, the screw could bottom out and prevent full installation.

The overall length of the Tapcon® concrete screw chosen for any particular application is also important. Different lengths are used depending on the thickness of the material being fastened. The minimum length is 1″ and the maximum length is 1-3/4″. Any length that falls between the numbers obtained should work in the application.

Are Tapcon concrete screws rust proof?

Stainless steel products can be tested for their quality by placing a magnet on the item. If the magnet sticks, it indicates that the product is made of 410-grade stainless steel, which resists corrosion in various environments. Stainless steel tapcons are coated with Climaseal®, a thermosetting polyester coating, which provides superior rust resistance. This coating is applied using a three-step process: cleaning and pre-treating the concrete screws, mechanically applying a zinc overcoat, applying the first coating by dipping and spinning each screw, and drying the screws in a furnace before applying the second coat.

Tapcons are available in two diameters: 3/16″ and 1/4″. The 3/16″ diameter is available in the flat Phillips countersunk head, while the 1/4″ diameter has two head styles: hex washer head and flat Phillips countersunk head. Each diameter of Tapcon® screw requires the correct bit to match the tolerance needed for the concrete screw to achieve adequate holding values. The bit length increases with the screw length, with the longer screws requiring a longer bit.

Are tapcon screws for exterior use?

The Tapcon® concrete screw, with its Climaseal® coating, offers excellent rust resistance for both indoor and outdoor use. Available in two diameters (3/16″ and 1/4″, these screws require a 5/32″ hole in the concrete and come in hex slotted washer head and flat Phillips countersunk head styles. They come in seven different lengths, while the 1/4″ screw comes in nine different lengths. Each box of 100 screws is packaged with a matched tolerance carbide tipped concrete bit.

Why do Tapcon screws keep breaking?

The depth of a Tapcon® hole should be at least 1/2″ deeper than the screw will penetrate, allowing space for the material created during installation and preventing the Tapcon® screw from bottoming out before the head is seated against the fixture. To ensure proper drilling, use a depth gauge on a hammer drill or tape the bit at the proper embedment depth. Additionally, clean the hole before using the screw to tap threads in the base material to prevent dust buildup and potential breakage or shear off. Too much torque may cause the Tapcon® screw to break or shear off.

Do Tapcons hold better in brick or mortar?

The Tapcon concrete screw is suitable for various base materials, including brick and mortar joints. The holding values of the Tapcon in brick depend on the brick itself and the quality and quantity of mortar in the joint. When drilling holes into brick for Tapcon concrete screws, a hammer type drill is used, breaking up the base material and pulling it out. A carbide-tipped bit meeting ANSI standards is used to ensure proper hole tolerance.

The number of holes that can be drilled with one drill bit depends on factors such as the abrasiveness of the brick, the depth of the hole, the type of hammer drill, and the operator technique. Most hammer drills require minimal pressure for optimal efficiency.

What screws to use for exterior?

Stainless steel nails and screws offer long-term corrosion protection but have a lower strength-to-weight ratio than aluminum fasteners. There are two types of stainless steel fasteners for outdoor use: 304 and 316. 304 fasteners are highly rust-resistant and suitable for drier climates, while 316 fasteners, also known as marine grade fasteners, resist corroding and pitting from chlorides, making them ideal for coastal areas. Roofing nails, with a diamond-shaped point and electrogalvanized zinc layer, are budget-friendly and suitable for various outdoor projects.

Galvanized steel is the best choice, but other materials like aluminum, stainless steel, and copper are also available. Copper nails, a high-cost option, are used on slate roofs due to their longer lifespan compared to galvanized steel.
