Customer Reviews (4.6 / 5 · 5 reviews)

Riley Z. ★★★★★

The threads are cut clean and the zinc yellow plating is even, so they slipped into the bracket without any binding. The partially threaded shank gave me the solid grip I needed for the steel frame, and all fifty came out of the box straight.

Lucy ★★★★★

Needed these for a trailer hitch bracket and the unthreaded grip length was spot on for aligning the holes. The plating looks even and clean, no flaking. A solid value for a fifty-pack.

Scarlett ★★★★★

The partially threaded shank gave me a solid grip length for aligning two steel plates without any slop, and the yellow zinc finish still looks clean after a week in the garage. Pack came with all 50 bolts, every one threaded smoothly into the tapped holes.
