Which long screws are really necessary?
So I know an engineer should confirm everything, and are useful in most cases ,but lets see if I can get cheaper advise and experience form others. (I have paid for numerous other required Eng. stamps).
Also this is a storage/work shop so I am not as concerned.
I’m looking for best bang for the dollar(LIKE EVERYONE) in a 6″ screw for holding my horizontal furring strips on the walls. I’m in Ontario Canada, so less choice of stores willing to ship.
Wall inside -out
2 x 6 stud wall @ 16″ OC.
7/16 OSB sheathing
1 x 4 furring strips ( horizontal ) @ 12″
Vinyl Board Batten siding.
I have looked at FastenMaster TiimberLOK screws vs. HeadLok, as recommended here
Is a screw with a large washer style head, really necessary?
The tensile/ shear strength of the two are similar, but the TimberLok are cheaper.
Thanks for any advise.
