Customer Reviews (4.8 / 5 · 5 reviews)

Adam ★★★★★

Picked up a box of these for a small machine rebuild I’ve been working on. The threads are clean and consistent, and the zinc coating looks like it’ll hold up pretty well in my garage.

Sofia C. ★★★★★

Used these for a quick shelf rebuild in my garage, the hex head made it easy to drive them in with a ratchet. The zinc plating seems decent and none were bent or stripped in the package. Exactly what I needed for the price.

Riley ★★★★★

Installed a whole batch of these building a custom rack, and the hex heads held torque perfectly without stripping. The 8.8 steel feels solid, and the zinc coating looks clean and uniform across all 600 pieces.
