Joshua ★★★★★

Needed a thin profile lock for a tight assembly, and these jam screws fit perfectly — the hex socket drove smoothly without stripping. Worked great holding a set screw in place on a jig fixture.

William ★★★★★

The through hex socket makes these jam screws easy to drive even in tight spots, and the alloy steel feels solid when tightening down. They seated cleanly in the tapped hole without any binding, and the 100-count pack covers plenty of future jobs.

Joshua ★★★★★

Needed a reliable way to keep a spring from backing out in a tapped hole, and these socket jam screws fit perfectly. The alloy steel feels solid, and the hex drive seated them snugly without any wobble. Really clean locking solution for the application.
