Stainless Hex Set Screws for Attaching Thumb Studs
Shop stainless steel set screws in 4-40 or 6-32 thread for attaching thumb studs and other compact fastening jobs in knife making. The internal hex drive tightens with a standard Allen wrench, and the stainless resists corrosion for long-term use.
Choose 4-40 or 6-32 to match the threaded hole for a thumb stud or another small fitting on a knife. The hex socket makes installation easy and lets you tighten the screw exactly as far as the job calls for, and the stainless steel offers dependable holding power.
Keeping spares of both thread sizes on the bench lets you replace a worn set screw on a finished knife or move straight into the next build. Browse Torx and Phillips head screws in our knife screw selection, or let us know the thread size you are working with.
