FAQ
What is a step bolt?
A step bolt looks like a carriage bolt but has a much larger, flatter round head and a square neck. The big head spreads the load over more wood, so it won't pull through soft or thin boards.
What nut fits a 5/16-18 step bolt?
A 5/16-18 hex nut or nylon insert lock nut with a flat washer.
