Customer Reviews (4.6 / 5 · 5 reviews)

Henry ★★★★★

Needed these for a heavy equipment jig I'm building, and the 10.9 grade steel feels reassuringly solid. The fully threaded shaft made alignment quick, and the 55mm length was spot-on for my application.

Isabella ★★★★★

These bolts have a clean, deep hex socket that grips the driver bit securely without slipping, which is a huge plus for me. They also torqued down smoothly to spec without any galling, and the 55mm length was just right for my equipment frame.

Benjamin ★★★★★

The threading is crisp all the way down, so they drove in smooth without any binding on my jig setup. For a hundred pieces at this grade, the price feels right.
