Aurora R. ★★★★★

Bought these for a quick frame repair and the partially threaded shank gave me just the right grip length for the job. The zinc coating looks good and none of the threads arrived damaged. Solid value for a hundred bolts.

Jason G. ★★★★★

The zinc plating is holding up nicely even in my damp garage, and the unthreaded grip length makes alignment a breeze when I'm bolting steel brackets together. For a hundred bolts at this price, I can't complain about the finish on a few of them.

Sebastian Y. ★★★★★

The partially threaded shank gave me the perfect grip length for my steel frame brackets—no more struggling with threads cutting into the bolt hole. All 100 came out of the box straight and clean, and the zinc coating hasn't shown a speck of rust after a week of rain.
