Matthew D. ★★★★★

Used these to bolt down a jig on my shop press and the partially threaded shank made alignment way easier than full-thread bolts. The yellow zinc coating is holding up fine so far, no rust after a couple of weeks. Definitely solid for the price.

Abigail ★★★★★

The hex head on these cap screws fits my socket perfectly and the zinc coating looks clean and durable. I used them to secure a heavy workbench frame, and the partial threading made installation straightforward. Exactly what I needed for a solid hold.

Joseph S. ★★★★★

The hex heads on these 9/16 cap screws fit my socket perfectly without any wobble, and the yellow zinc coating looks like it'll hold up well in my shop. I used them to secure a heavy motor mount, and the partial threading made installation a breeze.
