Customer Reviews (4.4 / 5 · 5 reviews)

Miles S. ★★★★★

Finally found M20 bolts with a proper partial thread—the plain unthreaded shank makes aligning multiple plates so much easier. The hex heads grab a socket firmly without stripping, even when torqued down tight. Just what I needed for mounting heavy equipment.

Sofia ★★★★★

The 70mm length was perfect for my machine baseplate—the partial threading let me get a clean bite without bottoming out. These held tight under heavy vibration with no loosening so far.

Mia ★★★★★

Had to swap out a few snapped bolts on a press jig and these threaded in clean with a socket, no fighting the threads. The 8.8 steel felt solid torquing to spec, and the partial thread gave just the grip I needed.
