Hex Nuts

Hex nuts are the standard mate for the hex, carriage, and machine bolts running through your dock framing. The thing that matters is matching the coating: a galvanized nut on a galvanized bolt, stainless on stainless. Mixing them sets up galvanic corrosion that eats the connection from the inside.

We stock hex nuts in hot-dipped galvanized and 316 stainless in every diameter we carry in bolts, so you can order both in one pass and know they will thread and last.

Add washers under the nut in timber applications to keep it from pulling through. Browse hex bolts, carriage bolts, or the full fastener range.
