Customer Reviews (4.6 / 5 · 5 reviews)

Alexander ★★★★★

I needed strong, corrosion-resistant fasteners for a jig build, and the zinc plating on these M8 screws handles the shop environment perfectly. The flat head sits flush, and the partially threaded shank gave me just the right grip depth for my assembly.

Scarlett ★★★★★

These barely fit my precision fixture table but the fully threaded portion grabs cleanly and the hex drive didn't strip even torquing them down hard. Zinc coating looks uniform across all 100.

Adam ★★★★★

The packaging was spot on and every single screw measured true at 50mm. The partial thread is a lifesaver for the jig I built, and the 12.9 hardness means I didn’t have to worry about stripping the hex socket.
