 How to Identify Thread Pitch and Size | Tech Tips

This step-by-step video will teach you how to correctly identify thread pitch and size using calipers, a pitch gauge, and a thread identification guide. Topics covered include a visual guide to individual parts and names (crests, roots, flanks), the difference between tapered (dynamic) and straight (parallel) threads, the purpose of each (plus the need for sealants), followed by proper measurement procedures of both thread types.

Today, Brownells Firearm Support Tech Caleb Savant is NOT screwing around. Well, maybe he is, just a little. But in a good way. He shows us how to check thread pitch. Normally, you can get the thread pitch of, for example, a threaded muzzle by checking the information that came with the rifle or barrel itself. If you don't have that info, here's the easiest way to determine what the pitch is. You'll need a set of calipers and a thread pitch gauge. First, use the calipers to measure the diameter across the top of the threads. Then, grab the thread pitch gauge and find the part of the gauge that perfectly fits in the threads. Keep in mind that you'll need separate gauges for metric and English (standard) threads. Once you know the pitch, you can buy the muzzle device, accessory, or replacement part you need - and know it'll fit.
