Customer Reviews (4.6 / 5 · 5 reviews)

Samuel ★★★★★

Pulling these out of the pack, the hex head cut cleanly into my socket without any rounding. The 7-1/2 inch length was exactly what I needed for that thick bracket assembly, and the yellow zinc coating looks solid.

Harper Z. ★★★★★

The threads are clean and the yellow zinc finish looks evenly applied, no flaking or rough spots. I used them to bolt down a motor mount and the 7-1/2" length gave me plenty of bite without having to stack washers. For the price, you're getting real grade 8 quality that I can actually trust with hea

Matthew ★★★★★

Finally found some long 1/4-20 screws that didn't bend while torquing—these Grade 8 bolts are seriously tough. The yellow zinc coating looks great and hasn't shown any rust yet. Perfect for my heavy equipment build.
