Customer Reviews (4.6 / 5 · 5 reviews)

John Q. ★★★★★

The zinc yellow plating looks clean and uniform across all 100 bolts, and the partially threaded shank gave me exactly the grip length I needed for a snug fit through steel brackets.

Elizabeth G. ★★★★★

These bolts lined up perfectly through my steel brackets, and the yellow zinc finish looks nice against the metal. The threading was clean and started easily without any binding.

Avery R. ★★★★★

The unthreaded grip length on these made aligning my steel brackets a breeze, and the zinc yellow plating seems tough enough to resist garage moisture.
