Riley X. ★★★★★

The threads cut clean and the hex heads grabbed a wrench without any rounding. I used a full 50-count box on a jig frame and didn't get a single bad one, and the B7 alloy feels plenty tough for my shop equipment. For the price per piece, these are a solid buy.

Violet ★★★★★

I needed heavy-duty bolts for a press repair, and these 8-1/2" long B7 alloy steel screws were exactly the right call. The partial threading made installation through the flanges and into the nut smooth without binding.

Elizabeth G. ★★★★★

These bolts seated perfectly into my heavy-duty press frame, and the hex heads gave my socket wrench a solid grip. The 8-1/2 inch length was exactly what I needed for a thick flange assembly.
