Penelope ★★★★★

I’ve been using these in a tooling fixture for a few weeks now and the low head profile is perfect for tight spots where a standard cap screw won’t fit. The 18/8 stainless finish is smooth and the threads cut cleanly without binding. Just wish the box had a divider—they all rolled together in shippi

Alexander G. ★★★★★

The hex socket drives seated perfectly with my Allen key, and the 18/8 stainless finish on these fully threaded screws is clean and uniform across the whole pack of 100. They held up great in a jig I built, no stripping or rust spots after a few weeks of use.

Daniel ★★★★★

Used these on a custom tooling fixture and the low head profile let me fit them into a tight spot where a standard cap screw would have stuck out. The hex drive seated perfectly without stripping, and the stainless finish looks clean against the aluminum.
