Ryan ★★★★★

Pulled a few of these out for a jig I’m building and the threads cut clean with zero binding, even with a socket wrench. The 3-inch length gives plenty of grip for thicker brackets, and the hex head seats nicely in tight spots. Solid batch for the price.

Edward J. ★★★★★

The yellow zinc finish on these bolts is holding up perfectly in my slightly damp workshop, no rust after a week. I’ve already used a dozen to secure a motor mount, and the threads catch cleanly every time.

Thomas B. ★★★★★

Finally, hex bolts that don't strip after one use—the PFC9 alloy feels noticeably tougher than the hardware store stuff. I used them to mount a steel bracket, and the yellow zinc coating looks solid too.
