Customer Reviews (4.8 / 5 · 5 reviews)

Penelope M. ★★★★★

I needed some long fasteners for a production jig, and these 4-inch cap screws fit perfectly with no threading issues. They drove cleanly with a socket wrench, and the hex head held up well under torque. Solid industrial quality.

Mia V. ★★★★★

Threads were clean and uniform across all 25, no burrs or sloppy machining. The 7/16-20 pitch seated perfectly with a socket wrench, and the zinc finish has a nice, even luster that should hold up in the shop.

Samuel W. ★★★★★

The yellow zinc coating on these bolts is really consistent and even, no flaking or rough spots at all. I used them to secure a heavy-duty jig and they tightened down smoothly without any binding. Perfect for the job.
