Elizabeth G. ★★★★★

The square neck on these bolts grabbed the wood perfectly as I was tightening them down on a shed door hinge, no spinning at all. Fast shipping too, exactly what I needed for the job.

Ryan ★★★★★

Installed these on a heavy wooden gate using a 7/16" drill bit — the square neck seated perfectly into the wood, and the fully threaded shank gave me plenty of grip. The 300-count package means I’ll have extras for future projects.

Amelia V. ★★★★★

The fully threaded design on these 7/16 bolts made driving them deep into the wood a breeze, and the plain steel finish feels solid for the price. I ordered the 300-count pack for a deck rebuild and each one seated perfectly without stripping.
