Samuel R. ★★★★★

Needed a solid batch for a framing project and these bolts held up perfectly through the clearance holes without any binding. The unthreaded grip length made alignment much easier than dealing with fully threaded ones. Exactly what I expected for the price.

Avery D. ★★★★★

These bolts fit perfectly through the clearance holes I drilled, and the partially threaded shank gave me just the right grip length for a solid connection. The hex head grabbed nicely with my socket wrench, making installation quick. A solid buy for heavy-duty fastening jobs.

Robert ★★★★☆

The unthreaded grip length saved me a ton of time aligning these in steel channels for a rack build. They threaded smoothly into the nuts and held tight without any wobble. A few bolts had a slight burr on the threads, but nothing a quick pass with a file didn't fix.
