Customer Reviews (5.0 / 5 · 5 reviews)

Abigail ★★★★★

I needed a few for a trailer hitch repair and these fit perfectly into the existing threaded holes with no binding. The yellow zinc coating looks evenly applied and should resist rust well in our damp shop.

David K. ★★★★★

I was replacing worn bolts on my press and these seated perfectly with no wobble. The yellow zinc coating looks clean and should resist rust well.

Robert Q. ★★★★★

The partially threaded design made all the difference when I needed to clamp two flanges together—the threads grabbed cleanly and the smooth shank did the work. Grade 5 yellow zinc looks solid and shows no wear after a week of hard use.
