Customer Reviews (4.8 / 5 · 5 reviews)

Emma X. ★★★★★

Wasn't sure about the partial threading at first, but it made aligning the bolt through a bracket and into the frame so much easier. The Grade 5 steel feels solid, and the yellow zinc coating gives them a clean, durable look straight out of the bag.

Matthew K. ★★★★★

The hex heads fit my socket perfectly and the yellow zinc finish gives them a nice, corrosion-resistant look. I used these to secure a motor mount on my lathe and the partial thread let me get a solid grip without bottoming out. Just what I needed for heavy-duty assembly.

Madison ★★★★★

The partial threading on these hex head cap screws makes alignment so much easier when working in tight spaces on equipment assemblies. The yellow zinc coating looks clean and seems durable, and the 3-3/4" length worked perfectly for my machinery repair.
