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.
How do carriage bolts work?
The square neck under the round head pulls into the wood as the nut is tightened, so the bolt can't turn. Only the nut side needs a wrench, and the smooth domed head is hard to remove from the outside.
