What does the #10 mean on a 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 does a #8 screw mean?
Their size is described as diameter, number of threads per inch (if used with a nut or in a threaded hole), and length in inches. … In all cases, the larger the number, the larger the size. Consequently a #8 screw is larger than a #4 screw, just as a 3 inch bolt is larger than a 2 inch bolt.

What size screw do I have?
Screw size is measured in diameter. For example a 1/4-20 screw has 20 threads per inch and a diameter of 1/4 inch. All you need is a steel rule to determine the size and thread count of any screw. Once you learn how to do so, household projects will be much easier.
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.
