Customer Reviews (4.8 / 5 · 5 reviews)

Avery V. ★★★★★

The black oxide finish on these M20 screws held up perfectly during a heavy clamping setup on my press. They threaded in smoothly and the extra length was exactly what I needed for a thick fixture plate.

Thomas Z. ★★★★★

I needed these for a jig on my mill, and the 12.9 alloy steel feels incredibly solid. The hex drive seated perfectly, and they threaded in smoothly without any binding.

Penelope ★★★★★

Used these M20 bolts to build a custom jig and the black oxide finish held up perfectly against chips and coolant. The partially threaded shank gave me just the right grip length without over-tightening. They feel tougher than any 10.9 bolt I've handled before.
