Customer Reviews (5.0 / 5 · 5 reviews)

Alexander N. ★★★★★

These bolts drove through a thick steel bracket without any binding, and the plating looks like it'll hold up well in a damp shop. The thread engagement felt precise right from the start, which made assembly go faster than I expected.

Claire Q. ★★★★★

Put these on a heavy trailer hitch build I was doing and they seated perfectly with no binding, the zinc coating looks even and thick across all twelve bolts.

Samuel X. ★★★★★

The threading is clean and consistent down the shaft, and the zinc coating looks like it will hold up well in my shop jig setup. These bolts seated firmly without any binding, which saved me time on a multi-bolt assembly.
