What size screws deck framing?
Most decking screws are 8-gauge and, while 2 1/2 inches is the minimum length needed to hold decking boards to the joists, 3-inch screws are commonly used to provide extra holding power against the upward pressure of shrinking or warping boards.

How far apart should deck joists be?
For residential decking, the joist space should not exceed 16 inches as measured on the centre. But if you want a more rigid feel for your decking, you can space the joist by 12 inches on the centre. Additionally, for commercial deckings, the standard joist spacing is 12 inches on the centre.
Should deck boards be butted together?
We recommend butting treated deck boards together because as the moisture dries from the wood, the boards will shrink and naturally form gaps to allow water drainage.

What are the best screws for framing?

A few other tips: When choosing the length of nail or screw, the fastener should be 1.75 to 2 times the length of the pieces you are connecting.
Can you use 2×6 for deck joists?
2×6 joists should only be used on ground-level decks that do not require, and will not provide for, any guards. Most decking is not strong enough to support longer spans than 16″. Some builders reduce joist spacing to 12″ on center to strengthen the deck frame or to increase maximum allowable joist spans.
Is toe nailing strong?
Toenailing not only makes a strong joint but also is a great way to coax stubborn boards into position. Photos 1 – 3 walk you through the basic steps of toenailing. The key to success is starting the nail in the right spot and angling it a little steeper than 45 degrees.
