Olivia G. ★★★★★

Ordered these for a metal shelving repair, and the 3/8" length was exactly what I needed to avoid poking through the back. The zinc yellow plating seems durable and matches the finish on my existing hardware well.

Penelope J. ★★★★★

Finally found bolts short enough for flush-mounting a bracket without a spacer. The 3/8" length is perfect for thin metal to metal connections and the threads are clean all the way through.

Christopher R. ★★★★★

Yellow zinc has held up well even in my damp garage, and the 3/8" length is perfect for thin brackets. I grabbed a pack for a few metal assembly projects and used most of them already.
