What Size Screws Are Needed For An Inside Door?

This guide provides a step-by-step guide on installing an interior door, which is a simple home improvement upgrade. The process involves shimming the door before it goes in and marking the location of the hinges. The pre-hung door is then placed in the door opening, keeping the jamb flush with the wall. The door plug is removed from the latch hole, and the door opens 90 degrees.

Prehung doors are easier to install than slab doors, but they still require some skills in your belt. To achieve professional-looking results, follow these steps:

  1. Shim the door before inserting it.
  2. Mark the location of the hinges on the door.
  3. Insert the pre-hung door into the door opening, keeping the edge of the jamb flush with the wall.
  4. Remove the door plug from the latch hole and swing the door open 90 degrees.
  5. Install shims, standard screws, and a trim saw.
  6. Check all gaps and ensure the screws penetrate the framing a minimum of 1 inch.
  7. Secure the hinge side of the jamb with 3″ 8 screws, covered by the door stop. If needed, use a 3″ screw to adjust the head jamb.
  8. Drive in a 2-3″ screw through the hole into the framing to hold the door up better.
  9. Shim behind all hinges and put a 3″ inch screw through the top hinge.
  10. Prepare for the installation by drilling 1/8 inch diameter pilot holes and installing 8 X 2-1/2 inch screws through the strike plate holes to secure the lock side.

The standard hinge screw size for residential doors is No. 9 screw, used for main doors and entry doors to houses. For a more solid door, shim solid behind the hinge area and use 1.5-3″ screws to get into the stud.

What screws are best for interior wood?

Steel screws are the most popular choice for woodworking and interior DIY projects due to their strength, affordability, and wide range of sizes. However, traditional tapered steel screws can be difficult to use and are often replaced by cheaper drywall screws. These screws are made from harder steel and can penetrate hard woods and manmade materials, but are brittle and snap when subjected to high drive forces or stress.

Production screws, made from hardened-steel with brands like GRK Fasteners, SPAX®, PowerPro™, and Saber Drive™, have sharp points and threads that can withstand high torque and stress. They are often sold as “construction screws” or “multipurpose screws”.

Handened steel screws are not weather-resistant and are best reserved for indoor projects. Deck screws, which have been plated or coated to increase corrosion resistance, are ideal for outdoor projects like playhouses or decks. Silicon bronze and stainless steel are the two best screw materials for greater resistance to rust and corrosion. Chromium alloy stainless steel screws come in two popular grades: Grade 305 stainless for applications where coated deck screws lack sufficient corrosion resistance, and Grade 316 for projects exposed to salt air or in areas where severe corrosion is likely to occur.
