Frequently Asked Questions
Why does a carriage bolt have a square neck?
The square neck beneath the round head wedges into the wood as the nut is tightened, preventing the bolt from rotating. This allows tightening from one side only — perfect for deck and fence construction where you can not access the back side of the bolt.
How long will the galvanized coating last outdoors?
Hot Dipped Galvanized fasteners have a thick zinc coating that provides excellent outdoor corrosion protection — typically 20-50+ years in moderate environments. For coastal/marine use, consider stainless steel for longer life.
