Customer Reviews (5.0 / 5 · 5 reviews)

Steven ★★★★★

Put these into a heavy-duty press application at work and the partially threaded section made alignment a lot easier. The yellow zinc coating on the grade 5 steel seems durable so far without any flaking.

Samuel ★★★★★

These bolts threaded in cleanly with just a socket wrench, no binding at all. The yellow zinc coating looks more durable than cheaper chromed fasteners I've used before. A solid set for the price.

Zoe H. ★★★★★

I was surprised by how consistent the threading is on these cap screws—every single one spun cleanly into place without any binding. They feel solid for heavy machinery work, and the yellow zinc coating gives a nice corrosion resistance right out of the box.
