Customer Reviews (5.0 / 5 · 5 reviews)

Grace ★★★★★

The hex socket drive made these easy to torque down without stripping, even in tight spots on my fixture. All 400 pieces arrived clean and uniform, with the red patch holding them snug during vibration testing.

Thomas O. ★★★★★

I needed some small screws for a jig I was building, and these 18/8 stainless ones are perfect—the red patch holds them snugly in place under vibration. The whole 400-pack will last me through many projects.

Abigail ★★★★★

The hex socket drive makes it easy to get a good grip without stripping the head, which is a huge plus for precision work. Pack of 400 means I'm set for a long time, and the stainless steel feels solid.
