Customer Reviews (4.8 / 5 · 5 reviews)

Leo ★★★★★

I needed some heavy-duty bolts for a press frame repair, and these cap screws threaded in with almost no resistance—the hex head took a socket wrench perfectly. The yellow zinc coating looks clean and industrial, which is exactly what I wanted for the project.

Eli ★★★★★

The partially threaded design made installation in my tractor's mounting bracket much easier than fully threaded bolts would have. These Grade 5 screws feel solid and the yellow zinc coating seems durable.

Sophia ★★★★★

Grabbed a pack for a jig I'm building and the yellow zinc finish is a nice touch—makes them easy to spot in the parts bin. The partial threading gave me just the right grip for the clamping load I needed, and they threaded clean without any binding. Solid feel for the price.
