Customer Reviews (4.8 / 5 · 5 reviews)

Natalie F. ★★★★★

Perfect length for my fence repairs — the 7-1/2" size was exactly what I needed, and the zinc plating looks clean and solid. All 50 bolts arrived with threads intact and the square neck seated snugly right away, no grinding or filing needed.

Abigail ★★★★★

The square neck on these bolts grabbed tight into the wood as I tightened them, no spinning at all. Needed them for a heavy-duty shelf bracket, and they held perfectly.

Ellie M. ★★★★★

The zinc plating looks clean and even across all fifty bolts, and the 7-1/2" length gave me plenty of bite when framing my deck railings. Threads were sharp enough to start by hand, which saved me time on the first few installs.
