Framing a stud wall nail size to use

[markblue777]

Hey All,
Just bought myself a 1st fix nailer as I have a few stud walls to make for my extension, just wondering what size nails to use in it for making them up. I was thinking 65mm but should it be 75mm?
Cheers
Mark

90mm is a common size, stud walls are usually skew nailed so the effective depth of the nail is less than straight through.

90mm.

Nailing 2 bits of 4x2 in a T you'll be at least 50mm up the side of one piece and then the 50mm thickness of the cross piece and at an angle and you'll not be out the other side.

90mm, as the others have said. One of the beauties of a nailer is that you can makes frames flat on the floor much easier than with a hammer. You only have to hold the plate and stud together in the correct position for a nano-second, and the nail gun doesn't knock all of the rest of the as-yet-unfixed framing all over the place as banging away with a hammer does. Try to nail from below if you can, and try to "dovetail" your nails to reduce any chance of pull-out.
