Customer Reviews (4.8 / 5 · 5 reviews)

Eva Z. ★★★★★

The hex socket drive seated perfectly with my Allen key, and the 12.9 alloy steel feels seriously tough for the price. I've used about fifty of these on a jig build so far, and the zinc plating hasn't shown a single scratch.

David ★★★★★

I needed a bulk order of M4 fasteners for a jig I’m building at work, and these 30mm screws with the hex socket drive make assembly much faster than using a wrench. The zinc plating feels smooth and uniform across all 400 pieces.

Evelyn ★★★★★

The partially threaded design on these M4 screws made aligning them in my jig setup much faster. They hold firm under torque, and the hex socket drive gives a clean, secure fit.
