Customer Reviews (5.0 / 5 · 5 reviews)

Jason F. ★★★★★

The square neck grabbed tight into the wood as I tightened the nut, no spinning at all. These 5/8-inch bolts are solid and the 6-inch length worked perfectly for my heavy-duty bench build.

Madison ★★★★★

I needed a full 6-inch length to go through thick PT lumber for a deck repair, and these fully threaded bolts fit the bill perfectly. The smooth rounded head looks clean on the surface, and they've held tight so far.

Claire ★★★★★

The square neck grabbed perfectly on my new deck frame, so these 5/8-11 bolts didn't spin at all while I tightened the nuts. All 50 came without any burrs or rust, plus the 6-inch length was just right for sandwiching two layers of 2x lumber.
