Customer Reviews (4.8 / 5 · 5 reviews)

Madison ★★★★★

I used them to secure a jig on my milling table, and the 316 stainless steel is holding up perfectly against cutting fluid splashes. The fully threaded length made it easy to dial in the exact clamping force I needed.

Sofia ★★★★★

The hex socket drive grips perfectly with a ball-end Allen key, and the 316 stainless finish is smooth with no burrs along the threads. Tossed them into a saltwater-exposed jig frame and after three weeks of use, not a single spot of rust anywhere.

Joshua T. ★★★★★

Used these on a custom fixture build and the 316 stainless finish is flawless—no galling even after torquing them down repeatedly. The fully threaded length gave me extra grip in thinner sections. Packaging was solid too, all 100 arrived clean and undamaged.
