Thomas ★★★★★

I needed some heavy-duty fasteners for a piece of farm equipment, and these grade 5 cap screws handled the load without any stripping. The yellow zinc coating seems like it'll hold up well against moisture.

Richard A. ★★★★★

The threads engaged cleanly on my shop press rebuild, and the yellow zinc coating looks sharp against the steel frame. For a partially threaded 4-1/2" bolt, the grip section is long enough for my spacer stack without any slop. These are my new go-to for heavy equipment fixes.

Emma Q. ★★★★★

Just installed a set of these on a mounting bracket I’ve been fabricating, and the partially threaded design really saved time aligning everything. The yellow zinc coating looks solid, too—no rust worries in my shop.
