Scarlett ★★★★★

I was a little skeptical about the price at first, but these cap screws are seriously strong—the yellow zinc coating on the PFC9 alloy steel has held up well without any rust after a week of outdoor use.

James A. ★★★★★

The hex head on these screws grips the socket perfectly, and the yellow zinc finish is holding up well in my shop. Made in the USA quality that's worth paying a little extra for, especially when you need consistent thread engagement.

Edward ★★★★★

Grabbed a box for some equipment repairs and the hex head makes it really easy to get torque with a socket. The yellow zinc finish looks clean and feels solid.
