Customer Reviews (4.6 / 5 · 5 reviews)

Claire C. ★★★★★

Installing these into a jig yesterday, the hex socket drive seated perfectly without any stripping. The threads are clean and consistent across all 700 pieces, which saved me a ton of time during assembly.

Henry ★★★★★

Needed a solid batch of socket cap screws for a precision jig I'm building, and these 18/8 stainless ones fit perfectly without any burrs. The hex socket drive grabs the Allen key cleanly, making assembly quick.

Stella F. ★★★★★

Installed a batch on a new tooling fixture and every screw seated perfectly with no cross-threading. The hex socket drive made tightening in tight spots a breeze, and the 18/8 stainless feels solid for the price.
