Customer Reviews (4.8 / 5 · 5 reviews)

Sebastian Y. ★★★★★

The partially threaded design made these perfect for clamping down a thick bracket on my press—no wasted shank length. The yellow zinc coating looks clean and hasn’t shown any rust after a few weeks in a semi-damp shop. Solid grip with a socket, too.

Chloe I. ★★★★★

Needed some Grade 8 bolts for a heavy-duty jig I'm building, and these went in perfectly with a socket wrench—the yellow zinc coating looks consistent and should hold up well.

Jacob L. ★★★★★

Put a set of these in a press fixture that sees a lot of vibration, and the partially threaded shank gave me a solid grip without any loosening. The hex head fit a standard wrench perfectly, and the yellow zinc coating looks consistent across all 100 pieces.
