Customer Reviews (5.0 / 5 · 5 reviews)

Riley ★★★★★

For a small medical device prototype clamp, the 316 stainless is noticeably smoother and more corrosion-resistant than the 18-8 I usually get. The hex socket drive held up perfectly under repeated torque without any stripping.

Robert ★★★★★

Used a full package on a custom jig I’m building, and every single screw threaded cleanly without any galling on the 316 stainless. The hex drive held up perfectly to my torque wrench, and the 3/4" length gave just enough grip for my aluminum plates.

Leo J. ★★★★★

The hex socket drive on these 316 stainless screws is clean and precise—my Allen key seated perfectly every single time. I used them for a jig build and the 3/4" length was spot on for the material stack.
