Timothy ★★★★★

These bolts fit perfectly into my motorcycle frame mounts, and the 18/8 stainless steel feels solid with no surface rust after a week of outdoor use. The 80-pack is plenty for a few projects, and the partially threaded shank gave me a clean grip where I needed it.

Claire ★★★★★

The unthreaded grip length on these bolts made aligning my steel brackets much easier than with fully threaded ones. The stainless steel finish looks clean and professional on the outdoor gate I just installed.

Matthew V. ★★★★★

These hex bolts fit perfectly into my boat trailer frame, and the 18/8 stainless steel gives me confidence they won't rust out after a season in saltwater. The unthreaded grip section along the shank made alignment much easier during assembly.
