Evelyn J. ★★★★★

The zinc plating on these heavy hex screws is holding up perfectly in my outdoor equipment jig, no rust after a week of rain. The 5/8-11 threads catch right away with a wrench, and the partial threading makes seating them fast. Exactly the heavy-duty grip I needed for a steel frame repair.

Elizabeth T. ★★★★★

The threads cut cleanly into my steel brackets without any binding. I've been using them for a heavy equipment jig, and the partial threading gives just the right grip.

Sofia D. ★★★★★

Zinc coating looks even and thick, no flaking when I torqued them into steel. The 2-3/4" length with partial threads gave me just the right grip for a heavy equipment mount, and all 125 came out of the box clean and true.
