Ella T. ★★★★★

Needed a box of 400 for a jig project, and these flat head M8s came in exactly as spec'd. The Class 10.9 alloy steel feels tough, and the zinc plating gives them a clean look that resists surface rust.

Ellie E. ★★★★★

Picked up a box of these for some precision assembly work and the hex socket drive made seating them quick and easy. The zinc plating looks consistent across all 400 pieces, which I appreciate for corrosion resistance. They’ve held up well under the clamping load I needed.

Mia ★★★★★

I needed some strong fasteners for a jig I’m building, and these alloy steel screws have a nice solid weight to them. The zinc plating looks clean and consistent across all 400 pieces, which is a relief compared to some cheaper packs I’ve tried.
