Samuel ★★★★★

The threading on these bolts is nicely consistent, and the zinc plating gives them a clean, durable finish. I used them to secure some heavy brackets in my garage, and the partially threaded shank provided exactly the solid grip I needed.

Timothy ★★★★★

I needed a clean grip length for a trailer hitch repair, and these bolts slid right through the brackets before the threads caught. The zinc plating has held up well during a week of rain, no rust spots yet. Exactly the right spec for my application.

Kevin ★★★★★

The partially threaded shank gave me just the grip length I needed for a snug fit on my steel brackets. Zinc plating looks clean and should resist rust well enough for my garage setup. Smooth hex head, no stripped corners.
