Penelope O. ★★★★★

Zinc plating is holding up well in my shop, no rust after a few humid days. These 5/16-18 x 5/8" hex cap screws threaded smoothly into the frame I was assembling. Sturdy little fasteners for the price.

John O. ★★★★★

The hex heads on these screws are crisp and fit my socket wrench perfectly, no slippage at all. They threaded smoothly into the steel brackets I was mounting for a small machine guard. A solid buy for basic hardware jobs.

Ruby O. ★★★★★

The zinc plating looks evenly applied and hasn’t shown any rust after a few weeks in my shop. Threads cut cleanly into pre-tapped holes, and the hex heads grabbed a wrench without stripping. Solid fasteners for the price.
