Customer Reviews (4.4 / 5 · 5 reviews)

Robert P. ★★★★★

I've been waiting on these for a machine rebuild and the yellow zinc finish looks even better in person, plus the Grade 5 steel feels solid in the hand. Every single bolt threaded cleanly into my brackets without a single stripped one out of the 200.

Isabella ★★★★★

These hex bolts are fully threaded, which made installing them into a blind hole much easier than I expected. The yellow zinc finish looks clean and the grade 5 steel feels plenty sturdy for my equipment stand.

Zoe ★★★★★

I was worried about stripping the threads on a heavy bracket, but these Grade 5 screws bit in perfectly with a socket wrench. The yellow zinc coating looks fresh and should resist rust well.
