Customer Reviews (4.6 / 5 · 5 reviews)

Benjamin D. ★★★★★

Torqued these into a custom tooling fixture today and they seated perfectly with no wobble. The black oxide finish is uniform and looks like it will resist a bit of shop grime.

Edward ★★★★★

Needed these for a heavy jig I’m building, and the 12.9 grade steel handled the torque without any flex. The hex socket drive seated perfectly with my allen wrench, and the 80mm length was just right for my setup.

Chloe L. ★★★★★

The black oxide finish on these M30 screws looks really clean and professional, and the 12.9 alloy steel feels incredibly solid. I used them for a jig fixture and they threaded in perfectly without any binding.
