Customer Reviews (4.8 / 5 · 5 reviews)

Thomas R. ★★★★★

The zinc coating on these bolts is holding up nicely in my outdoor equipment assembly so far, and the full threading makes them easy to cinch down tight. They threaded smoothly into the pre-tapped holes without any binding.

Isabella ★★★★★

I needed heavy-duty bolts for a machinery rebuild, and these hex cap screws fit the bill perfectly—the zinc plating on every single one looked uniform and didn't flake off during installation. The fully threaded length gave me plenty of grip without any stripped threads.

John B. ★★★★★

Threads cut clean and the zinc finish looks even across all 65 pieces, no flaking or rough edges right out of the pack. Bolted down a jig frame this morning and they torqued up solid without stripping. Exactly what I needed for heavier equipment work.
