Customer Reviews (5.0 / 5 · 5 reviews)

Evelyn O. ★★★★★

Bought these for securing a heavy press to the floor, and the hex head made tightening with a wrench effortless. The partial threading is a real bonus for alignment.

Brian ★★★★★

The threads are clean and the partial threading makes seating them in a flange much easier than dealing with a fully threaded bolt. These M20s feel solid in the hand, and the hex head grabs a socket without any wobble.

Emma ★★★★★

I needed these for a heavy equipment frame repair and the partial threading made alignment much easier than with a fully threaded bolt. The 8.8 grade steel feels robust and the hex head took a socket without any rounding.
