3/4-10 Galvanized Carriage Bolts

These 3/4"-10 galvanized carriage bolts have a domed head and a square neck that locks into the wood, so you only need a wrench on the nut. They are hot dip galvanized for decks, fences, docks and treated lumber. We stock lengths from 2-1/2" to 24". Bolts 6" and shorter are fully threaded, and longer bolts have 6" of thread.

FAQ

What size hole do I drill for a 3/4" carriage bolt?
Drill a 3/4" hole. A snug fit lets the square neck bite into the wood so the bolt doesn't spin.

What if my 3/4" carriage bolt spins when I tighten it?
Tap the head down with a hammer to seat the square neck before tightening. In hardwood or old, dry lumber, a light tap is usually all it needs.
