Customer Reviews (4.6 / 5 · 5 reviews)

Isabella G. ★★★★★

The hex heads grab a socket perfectly without slipping, and the yellow zinc coating looks clean and uniform across all 700 pieces. I used these to repair a trailer hitch assembly and every single one threaded in smoothly.

Penelope R. ★★★★★

Needed a solid batch of 7/16-20 fasteners for a machine frame and these didn't disappoint—the yellow zinc finish is uniform and the threads are clean, so they drive in without any fuss. The full threading makes them easy to use in tight spots, and the hex head grabs a socket perfectly. Nothing fancy

Sebastian ★★★★★

I needed a full box for a big assembly job, and these fully threaded screws drove in evenly without any binding. The yellow zinc coating looks clean and has held up well so far. Solid purchase for industrial work.
