Do you need to drill pilot holes for wood screws?
Why Pilot Holes Are Necessary When you drive screws into wood without drilling pilot holes, you’re essentially pushing wood out of the way to make room for the screw. That displaced wood puts more pressure on the wood surrounding the screw, which can lead to splitting and cracking, weakening the wood over time.
How do I know what size drill bit to use?
Use a bit 1/64” smaller than the target hole size for softwoods. Use a bit exactly the same size as the hole when working on other materials. If you’re not sure which to select, choose a drill bit 1/64” larger than the hole you wish to create. This will account for variables such a wood density and screw type.
Is #8 or #10 screw bigger?
In the Imperial system of units, a number 10 machine screw (0.190 inch major diameter) is bigger than a number 8 machine screw (0.164 inch major diameter). The 8 is larger than the 10.
What diameter is a 12 gauge screw?

What size is a #10 screw?
The number “10” is used as a size designator and has no numerical meaning. “32” refers to the 32-thread pitch in threads per inch. You can identify a 10-32 screw by measuring the diameter with a ruler at exactly 3/16 inches ().
What is a standard screw?
The Unified Thread Standard (UTS) defines a standard thread form and series—along with allowances, tolerances, and designations—for screw threads commonly used in the United States and Canada. It is the main standard for bolts, nuts, and a wide variety of other threaded fasteners used in these countries.

How do I know what size my screw is?
How to Determine Screw Size & Thread CountLay the screw down on a flat surface. … Place a steel rule down the axis of the screw. … Count the number of thread gaps within 1 inch of the screw.Divide the count of thread gaps into the length. … Place the screw on a flat surface.Lay a steel rule between two screw threads and measure across the diameter.
Should you drill a pilot hole for wood screws?
First, drill a pilot hole through both boards. Pilot holes guarantee that your screw won’t break off and your wood won’t crack. For most hardwoods, the pilot hole should be at least as large as the screw’s minor diameter. If the screw has deep threads, or the wood is very hard, the pilot hole should be another 1/64-in.
What size wood screw do I need?
As a general rule, screws needed for attaching two boards across the grain do not need to be as long as when screws are inserted into end grain. When screwing into the end grain, aim for at least two inches of thread in the board. As a general guideline, you can use #8 diameter deck-type screws for most utility tasks.
