There are a lot of tricks and tools for spacing deck boards evenly, but how many of them give you perfectly aligned screw heads too? Jason Lindquist designed FastCap’s DeckMaster to help the amateur and pro alike build professional-looking decks.
The Deck Master can be used to provide a consistent 1/4″ gap when putting down either 4″ or 6″ deck boards. It straddles the joist to consistently align screws over the entire deck. There are two sets of guide holes: one for fastening the board mid-field and the other for attaching two boards to the joist edge to edge.
It looks like currently the only place you can find the Deck Master online is FastCap’s store. There you’ll pay $20 plus $8 shipping.
