Customer Reviews (4.6 / 5 · 5 reviews)

Chloe D. ★★★★★

The yellow zinc coating on these is much nicer looking than standard plain steel bolts. Threads were clean and the hex heads fit my socket perfectly for mounting a jig.

Ava ★★★★★

Installed these on a couple heavy lifting brackets and the threads were clean, no hesitation even with a ratchet. The yellow zinc finish looks consistent across all 50, which I appreciate for a uniform assembly.

Grace ★★★★★

I was pleasantly surprised how consistent the threading was across all 50 screws—each one seated perfectly in my jig without any binding. The yellow zinc finish seems durable enough for outdoor equipment, and the hex heads grabbed securely with my socket.
