Amelia ★★★★★

The threading on these 5/8-11s is clean and seated perfectly flush with the nut, no burs at all. The yellow zinc finish has held up well after a week of daily use on my equipment, and the hex head grabs a socket without slipping. Solid pack of 25 for the price, glad I stocked up.

Avery M. ★★★★★

I was replacing some bolts on a heavy assembly table, and these hex head cap screws tightened up solid with no wobble. The yellow zinc plating looks clean and seems like it will resist rust well.

Richard ★★★★★

Installing these on a press brake yesterday and the hex heads held up to a full 160 ft-lbs without stripping. The yellow zinc finish on the PFC9 alloy looks sharp too.
