Customer Reviews (4.8 / 5 · 5 reviews)

Owen S. ★★★★★

These hold up great under load for the price—the hex socket drive seated cleanly and the zinc plating looks even all over. I've used a dozen already in a jig build and haven't stripped a single one.

Hazel I. ★★★★★

The threads are clean and uniform on every screw I've checked, and the zinc finish looks even across all 400 pieces. I've used about sixty so far building a tooling fixture, and the hex socket drives are seating perfectly.

Sophia B. ★★★★★

Pulled these out of the pack for a jig I'm building and the threading is clean all the way down, no binding or stripped heads even with a bit of torque. Zinc plating looks uniform too, so they should hold up fine in the shop. For 400 pieces at this price, the 12.9 hardness is a real bargain.
