Customer Reviews (5.0 / 5 · 5 reviews)

Robert W. ★★★★★

Worked perfectly for mounting a bracket where I needed the extra length of a partially threaded bolt, and the 8.8 grade gives me confidence it'll hold under load.

Hannah ★★★★★

Had to replace some bolts on my lathe steady rest and these M4s threaded in smoothly with no binding. The zinc coating looks uniform and held up fine against a bit of coolant splash.

Andrew ★★★★★

Installing these into a 3D printer frame was a breeze — the hex head grabs a socket perfectly for tight torque without stripping. The partial threading is just right for clamping thicker brackets without bottoming out.
