Customer Reviews (4.8 / 5 · 5 reviews)

Owen C. ★★★★★

Installing them in a tooling fixture was straightforward, the hex drive seated perfectly without any slipping. The 316 stainless steel feels noticeably more corrosion-resistant than the usual 18-8 stuff. Exactly what I needed for a marine-adjacent assembly.

Stella W. ★★★★★

Used these on a custom jig build for a salty shop floor, and the 316 stainless is holding up perfectly without a hint of rust. The hex socket drive seated cleanly with minimal wobble.

Robert Q. ★★★★★

Installed these in a saltwater marine jig and the 316 stainless is holding up perfectly without any corrosion. The hex socket drive grabbed securely, no stripping when torqued to spec.
