Lag Screws are designed for the really big jobs–building docks, decks and wharfs. Installed properly, they have outstanding holding power, and do not need to be re-tightened frequently, as is sometimes the case with bolted connections. We offer these tough lags in either 18-8 stainless steel or hot-dip galvanized. Imported.
All 1/2 lag screws have a 3/4" hex head. See table below for thread lengths by overall length.
