Customer Reviews (4.4 / 5 · 5 reviews)

Timothy Q. ★★★★★

Perfect fit for my trailer hitch rebuild. The zinc coating on these is nice and even, no flaking when I torqued them down. Exactly what I needed for the square hole on the frame.

Ava ★★★★★

The square neck grabbed perfectly into the wood frame on my dock rebuild, no spinning at all. These bolts feel solid and the zinc coating looks like it'll hold up well outdoors.

James Y. ★★★★☆

The square neck grabbed hold nicely in the wood frame I was assembling, and the zinc coating looks clean. Only minor thing is that a couple bolts had slightly uneven threads, though they still worked fine with a little effort.
