Customer Reviews (4.6 / 5 · 5 reviews)

Miles X. ★★★★★

Used a few of these for a jig build and the hex socket drive seated perfectly without any stripping. The 140-count pack should last me through several more projects.

Leo M. ★★★★★

Packed 140 of these alloy steel screws in one box, and every single one threaded smoothly into my jig without a single stripped head. The hex socket drive grips the wrench perfectly, so even at 1-1/4" length they feel solid for precision assemblies.

Jacob ★★★★★

Installed these in a jig I’m building and the alloy steel feels solid, no stripping even under a wrench. Exactly the length and thread needed for my setup.
