Customer Reviews (4.8 / 5 · 5 reviews)

Richard O. ★★★★★

The 18/8 stainless steel finish is smooth and clean, exactly what I needed for a small outdoor project where rust could be an issue. They threaded easily into pre-tapped holes, and the fully threaded shank gave me a solid grip the whole way through.

Emma ★★★★★

I needed a bulk pack for a small metal framing project and these bolts fit perfectly. The 18/8 stainless seems solid, and having them fully threaded saved me time on a few tight assembly spots.

Joshua ★★★★★

The threads are clean and the stainless finish feels solid—I've put them through a couple of projects already and they haven't rusted or stripped. For the price, getting 200 of them in one box is a steal, even if the 3/8" length is a bit niche for my needs.
