Customer Reviews (4.8 / 5 · 5 reviews)

Ryan I. ★★★★★

These bolts threaded cleanly into my fixture plate without any binding, and the yellow zinc finish is holding up well after a few days of use. The partial thread gives just the right grip depth for thick flanges.

Sophia ★★★★★

Installing a new press in my shop and these cap screws fit perfectly in the hex socket. The yellow zinc finish on the grade L9 alloy steel seems tough enough to handle some serious torque.

Olivia O. ★★★★★

Put these on a heavy-duty press and the partially threaded design made alignment so much easier. The zinc coating looks like it’ll hold up to plenty of grease and grime without rusting.
