Aurora P. ★★★★★

Noticed these hex screws were burr-free right out of the pack; the threads started cleanly in my tractor's tooling jig. A solid improvement over the last batch.

Henry ★★★★★

Came out to exactly 2-1/4" under the head as advertised, which is rare for hex bolts. Threads are clean and sharp, and the yellow zinc has a nice even finish.

Samuel I. ★★★★★

The yellow zinc coating on these bolts looks really durable, and they threaded perfectly into my milling machine’s base without any binding. Exactly what I needed for heavy-duty equipment assembly.
