segued Posted July 5, 2021 Share Posted July 5, 2021 Hi I've recently removed all my decking & frame and I'm reconstructing from scratch. The decking is around 300mm from ground level so not too far. I've decided to use joist hangers to attach the joists to the ledger boards on each wall (the decking spans between the house and another wall). Is there any screws I can use to attach the hangers & joists rather than twist nails? Theres 64 nails per joist and it's taking me forever!

joe90 Posted July 5, 2021 Share Posted July 5, 2021 Screws don’t have the right strength quality for joist hangers, some people have used them but twist nails are the “proper” spec fir using with joist hangers. 1 Link to comment Share on other sites More sharing options...
markc Posted July 5, 2021 Share Posted July 5, 2021 (edited) Hi, yes there are screws available;e, one is Simpson Strong Tie. but they are not cheap. They have a small shank under the head and single thread. Edited July 5, 2021 by markc Link to comment Share on other sites More sharing options...

As @markc says, you can get special screws for hangers but they are pricey. Link to comment Share on other sites More sharing options...

If this is outdoor decking there is no need to have so many fixings per hanger. Could reduce 12 per hanger. 1 Link to comment Share on other sites More sharing options...

The joists are 2x6 and was told to use a hanger on the top and bottom to prevent twisting. There is 16 nail holes per hanger (8 into the board and 8 into the joist) - 2 hangers per end of joist and obviously 2 ends = a lot of hammering! I've used nails so far but I'm getting bored of hammering. I'll check out the recommended screws - thanks. Link to comment Share on other sites More sharing options...

I have never seen this and can't even see how you would do it. Just cut some noggins to go between the joists. Link to comment Share on other sites More sharing options...
