Customer Reviews (4.8 / 5 · 5 reviews)

Benjamin Z. ★★★★★

Zinc plated finish on these lag bolts held up well during a recent deck repair, no rust after a week of rain. The 4-1/2" length was perfect for securing the ledger board into the rim joist without needing to pre-drill all the way.

Sofia ★★★★★

The hex head gripped my socket wrench perfectly, no stripping even at full torque. These zinc-plated #3s sank into the treated lumber clean and the 4-1/2" length gave me solid bite for the deck frame.

Owen ★★★★★

Just used these to bolt down a heavy-duty bandsaw frame, and the hex head made it easy to get a socket on them in a tight spot. Really solid threading, no galling at all.
