Customer Reviews (4.6 / 5 · 5 reviews)

Kevin ★★★★★

The zinc coating on these is evenly applied and looks great, no flaking like on cheaper hardware. Used them to mount a heavy pump and the partial threading made alignment much easier. Definitely worth the price for the grade L9 strength.

Owen ★★★★★

These bolts are exactly the right length for the heavy equipment frame I'm working on, and the partially threaded section grabs perfectly for a clean, solid clamp. The hex heads are sharp and the yellow zinc gives them a tough, professional look. They'll definitely be my go-to for this kind of job.

Alexander ★★★★★

These bolts threaded perfectly into my tractor’s frame with no binding, and the yellow zinc coating looks like it'll hold up well against the weather. The L9 alloy steel feels noticeably tougher than the standard hardware I usually buy.
