Customer Reviews (4.2 / 5 · 5 reviews)

Timothy ★★★★★

The threading on these bolts is clean and consistent, which made them easy to drive without any binding. I needed them for a structural frame assembly and they held up perfectly under torque. The zinc plating looks good and should resist rust fine.

Owen G. ★★★★★

The threads on these 1"-8 hex bolts are clean and seated snugly when I torqued them down on my equipment frame—no galling at all. The zinc plating looks uniform across all 25 pieces, and the partial threading gave me just the right grip length for a heavy steel bracket.

Victoria S. ★★★★☆

Used these for a heavy equipment repair and the zinc coating held up well against the shop grime. The partially threaded design made alignment easier than I expected. Only wish the package included a few extra washers.
