Assembly with screws - Byubob - 02-05-2018 I am planning to build a 10' x 10' cover for my deck. I will be using 4x4 corner post with a 2x10 wrap at the top and 2x6 rafters. I plan to use galvanized brackets and hangers to hold it all together. My question concerns the lag screws. Do I drill a thru hole in the piece being attached and a pilot hole in the piece being attached to? If so, what size holes for #10 lag screws? Thanks, Bob RE: Assembly with screws - photobug - 02-05-2018 In softwood you generally go down 2 sizes. I would drill the outer board just one size smaller, predrill these holes on the ground then clamp into place and drill through the other piece of wood using a two step down sized drill bit. Sink your first bolt and then go and predrill the rest. I am not sure what #10 lag screws are. When I think of lag I think of bolts with square heads in 1/4 or bigger. I would look at Torx screws in this place. At size #10 you can just predrill the outer board to prevent splitting, and maybe an inch into the other board. Once started a Torx screw will drill itself. RE: Assembly with screws - EightFingers - 02-05-2018 You don’t use lag screws on joist hangers. There are special screws that must be used. RE: Assembly with screws - Cooler - 02-05-2018 I built my deck and nothing was 100% square or vertical. When I mounted the posts I used through bolts (hot dip galvanized). This allowed me to shim to plumb. My brother-in-law built his deck and he mounted it with lag bolts but when the posts were clearly not plumb, he did as I did. We both mounted on the 2" x 8" joists. I suppose you can shim with lag bolts but it is easier with through bolts. If your deck is 100% plumb and level ignore this advice. RE: Assembly with screws - photobug - 02-05-2018 Based on the "#10 lag screws" I assumed he was talking about fascia detail of the deck. I agree on Lag Bolts and specialty screws or nails for Simpson Ties. RE: Assembly with screws - rwe2156 - 02-07-2018 +1 on the thru bolts. Use 1/2" carriage bolts. Letting the plates into the posts in a rabbet is also something to consider. RE: Assembly with screws - Tapper - 02-08-2018 Don't quite understand what a "2x10 wrap" is? I would use 2x8's for the rafters just for a little margin (nothing worse than a sagging roof later) and those short stubby galvanized nails in the joist hangers and all other bracketry; they are specifically designed to secure them. If possible, I would use galvanized through bolts, washers and nuts to secure the framing where possible.

Wrap 2x10's around the top, outside of the posts. |
