Customer Reviews (4.6 / 5 · 5 reviews)

David ★★★★★

These bolts fit perfectly into the frame of my wooden trailer gate, and the 18-8 stainless steel finish gives me confidence they won't rust out here. Nice to have a full pack of 70 for just this one job.

Samuel ★★★★★

Installed these on a new workbench frame and the square necks seated perfectly in the wood, no spinning. The 18-8 stainless finish looks clean and should hold up well in my garage.

Sophia E. ★★★★★

The threads caught perfectly on my first try, and the 18-8 stainless has held up beautifully in a damp shed project. I just wish there were more than 70 in the package for the price.
