Claire N. ★★★★★

I was replacing some jig bolts in my workshop and these M12s threaded in smoothly right from the first turn—no binding at all. The 12.9 alloy steel feels really solid for the price, and the hex socket drive gave me a clean, tight fit without stripping.

Charlotte P. ★★★★★

The zinc plating looks clean and even on all 50, and the hex sockets were crisp enough that my Allen key seated perfectly every time. Threads ran smooth into my steel fixture without any binding, which is exactly what I want for a precision assembly.

Kevin P. ★★★★★

I needed a full dozen for a jig I’m building, and these M12-1.75 x 40mm screws came in a 50-count pack, so I’ve got plenty of spares. The hex socket drive seated perfectly in my wrench without any wobble.
