Customer Reviews (4.8 / 5 · 5 reviews)

Kevin C. ★★★★★

I've been using these for mounting heavy jig components, and the M20-2.5 thread holds torque perfectly without stripping. The black oxide finish hasn't shown any wear after several assembly cycles, and the hex socket drive makes installation straightforward.

Riley R. ★★★★★

Threads were clean and the hex socket seated deep on every one of the 25 pieces. Used them to bolt down a heavy jig plate and the 12.9 alloy steel feels properly rigid under load, with the partial threading giving just the right grip.

Olivia ★★★★★

The black oxide coating on these screws looks really professional, and the hex socket drive made installation a breeze on my jig setup. For a 25-pack of 90mm partially threaded screws, the price is fair and the Class 12.9 alloy steel feels solid.
