Customer Reviews (5.0 / 5 · 5 reviews)

Lucy L. ★★★★★

The partial threading made cinching down a motor mount bracket so much easier than dealing with fully threaded bolts. These grabbed cleanly with a socket and didn't strip at all during torquing.

Samuel ★★★★★

Grabbed a pack for a heavy-duty jig I was building — the hex heads fit a socket perfectly and the partial threading made alignment effortless. Zinc coating looks uniform, no rust spots after a month in a damp garage.

Jacob E. ★★★★★

The threading on these M8 bolts is clean and uniform, and the zinc plating gives them a consistent finish that fit snugly into my equipment frame without any galling. Having 200 in the pack means I won't need to reorder for a while, and the partial thread gives good grip where it counts.
