Customer Reviews (4.6 / 5 · 5 reviews)

Lily ★★★★★

The packaging was a solid, heavy box and every single one of the 1500 screws came out clean with no damaged threads. The yellow zinc finish is uniform and the hex heads are sharp, so my sockets grab them perfectly every time.

Richard ★★★★★

Used these to bolt a motor mount onto a heavy-duty press table at work, and every single one threaded in clean without a single jam. The yellow zinc coating feels solid and should hold up fine against occasional oil splashes. Exactly what you want from a bulk box of Grade 8 hardware.

Robert ★★★★★

Needed a full box of these for a production run and the hex heads held up perfectly under repeated socket torque without any stripping. For a 1,500-count box the price per screw is hard to beat when you're buying in bulk.
