Customer Reviews (4.6 / 5 · 5 reviews)

Michael Z. ★★★★★

These replaced a stripped bolt on a large press, and the Class 8.8 steel is holding up perfectly under constant torque. The partial threading made aligning the first few turns much easier than with a full thread.

Sofia ★★★★★

Needed some heavy-duty fasteners for a machine base I’m building, and these M30s drove in smoothly with a socket—no stripping or wobble. The partially threaded shaft made alignment a breeze, and the 130mm length gave me just enough bite. Solid hold for the price.

Madison J. ★★★★★

The hex head on these M30 screws gave my socket wrench a solid grip even when torquing into a tight spot on a jig frame. Nice to get partially threaded ones for a change, stops the threads from binding where they shouldn't. Clean threads and solid steel, did what I needed.
