Customer Reviews (5.0 / 5 · 5 reviews)

Julian G. ★★★★★

Installed these on a large jig frame and the partial threading made alignment much easier. The hex head gave my socket a solid bite with zero rounding.

Michael F. ★★★★★

Zinc plating looks even and clean, and the hex heads seat nicely in a socket without any stripping. These M20s drove in smooth for our press frame rebuild, and the class 8.8 rating gives me confidence they’ll hold up under repeated torque.

Jason ★★★★★

The partial threading on these is exactly what I needed for bolting into a heavy steel frame, and the zinc coating looks clean and uniform. All ten arrived with crisp, sharp threads that engaged smoothly—no chasing or filing required.
