Sofia ★★★★★

Good thing these bolts came in a 700-count package—I used almost half just securing brackets in my garage and still have plenty left for future projects. The zinc coating feels durable and should keep rust at bay for a while.

William ★★★★★

Full thread engagement along the entire shank is exactly what I needed for sandwiching metal brackets, and the zinc plating is already showing good corrosion resistance after a few rainy days. The 700-count box is a solid value for someone who burns through fasteners on the regular.

Sophia Z. ★★★★★

I've been using these fully threaded 5/16-18 bolts for assembling metal brackets and the zinc plating holds up well without rusting. The 700 count is a solid value for keeping my hardware drawer stocked.
