Customer Reviews (4.6 / 5 · 5 reviews)

Joseph ★★★★★

I was worried about stripping the hex socket on such a large screw, but these handled full torque on a jig frame without any issue. The threads are clean and precise, and the 12.9 alloy steel feels rock solid for the price.

Violet ★★★★★

The black oxide finish on these M30 screws looks really clean and seems durable. I used them for a jig build and the hex socket drive made installation straightforward.

Sebastian F. ★★★★★

These 12.9 alloy screws held perfectly on a tooling fixture under heavy load; the hex socket drive made tightening them a breeze. The black oxide coating seems durable, and they threaded smoothly without any binding.
