Customer Reviews (4.8 / 5 · 5 reviews)

Zoe A. ★★★★★

Needed these jam screws for a tight spot where a regular fastener head wouldn't fit—the hex socket cut perfectly into the collar, so I could drive it flush without any wrench clearance issues.

Michael R. ★★★★★

Perfect fit for locking down my spindle on the milling machine—the 5/8-18 threads engaged smoothly with no binding. These alloy steel jam screws feel solid and hold tight under vibration.

William B. ★★★★★

The through hex design made installation straightforward on my lathe, and the alloy steel feels robust even under heavy torque. I used them to lock a tool post in place, and they haven't budged since.
