Customer Reviews (4.6 / 5 · 5 reviews)

Miles ★★★★★

Bought these to bolt down a boat trailer bunk bracket and the threads cut clean with no galling, even after sitting outside through a few rainstorms. The 5-1/2" length gave me enough shank to clear the thick spacer plate I was using, and the hex head took a breaker bar without rounding.

Hannah N. ★★★★★

The 18/8 stainless steel on these is the real deal — no rust spotting after two weeks bolted to a dock plate in the rain. Threads were clean and they torqued down smooth with no galling.

Carter H. ★★★★★

Ordered these for a trailer hitch rebuild and the 18/8 stainless hasn't shown a spot of rust after two months outside. The partial threading lets the shank bite deep before the nut ever reaches the threads, which is exactly what I needed on the thicker plate.
