Customer Reviews (4.8 / 5 · 5 reviews)

James Q. ★★★★★

These fully threaded bolts worked perfectly for securing a heavy-duty press at the shop; the zinc coating should keep them from rusting in our damp basement.

William B. ★★★★★

Got these for rebuilding some industrial shelving units, and the fully threaded design made driving them into the uprights a breeze. The A307 grade steel feels solid and the zinc coating looks like it will resist rust well in a garage. Exactly the heavy-duty fasteners I needed for a reliable assembl

Edward ★★★★★

The zinc plating on these 7/8-9 x 2-3/4 heavy hex screws is nice and even, and the threads cut cleanly into the steel plate I was working on. A solid 60-count box for the price.
