Violet N. ★★★★★

Had to swap out some rusty bolts on my trailer hitch and these stainless ones should last way longer. The 18/8 material feels solid and the partial threading gives a nice clean grip before the threads bite.

Ellie F. ★★★★★

The unthreaded grip length on these made alignment a breeze when I was bolting through two steel plates, and the 18/8 stainless finish wiped clean after getting rained on overnight. Exactly the right thread engagement for my project, no stripping or wobble.

Richard H. ★★★★★

These bolts are solid and the stainless finish looks clean. The unthreaded grip section worked perfectly for aligning two fence brackets without the threads chewing up the holes.
