Amelia ★★★★★

Just put 12 of these into a jig for the press and the threads cut clean with zero binding a full 7/8" bite. The hex heads seated square without a single rounded-off corner, even wrenching them dry. At 450 per box I basically never have to reorder.

Abigail L. ★★★★★

The zinc coating on these Grade 8 bolts looks really uniform and has held up well so far during my trailer repair work. The hex heads grab a socket firmly without slipping, which I appreciate when torquing them down.

Avery ★★★★★

These cap screws fit perfectly in my socket and the yellow zinc coating gives them a clean, consistent finish. For the price, getting a full box of 450 Grade 8 fasteners feels like a solid deal for general shop use.
