Specifications

Why partially threaded green decking screws?

The plain shank lets the board pull down tight to the joist instead of riding up, which is what prevents jacking. A bulk pack of 1000 suits a full deck.

How to use

1. Lay the board and space it from the next.
2. Pilot drill near board ends.
3. Drive with a pozi bit until the countersunk head sits just below the surface.
4. Use two screws per joist crossing.
