How do I measure screw size?

Length is measured from the point at which the head sits flat with the surface, to the tip of the threads.

How do you read thread size?

How to Read Screw Sizes Read the first letter of the size. This the largest diameter: the measurement of the screw on the thread. Read the second number. This is either the number of threads per unit of the distance between threads; also known as the “thread pitch”. Read the third number, generally the one following the “x.”

What is a #10 screw?

The term 10-32 comes from Unified and American Screw Threads for Bolts, Nuts, and Machine Screws standards published by ANSI B1. 1-1974. The number “10” is simply a size designator with no numerical meaning. The number “32” refers to 32 threads per inch.
