Nicholas ★★★★★

The zinc yellow plating is holding up nicely in my garage projects without any rust so far. I used these to secure a mower deck and the 1-1/2" length was just right for the job.

James T. ★★★★★

The partial threads made aligning these bolts in my steel brackets so much easier since the unthreaded section acts as a pilot. Zinc plating gives them a clean, factory look and they've held up fine in my garage shelving project.

Julian O. ★★★★★

These are perfect for when you need a clean, strong fit and the unthreaded shank gives you that precise alignment. The zinc yellow coating looks uniform and should hold up well against light moisture in my shop.
