Question

shooting nails through 2x4s into concrete


i have a remington powder-actuated nail gun for fastening 2x4 into concrete.

Q1: which size nails should i use (3.5 in perhaps) ?
Q2: which strength ammunition should i use (1-6) ?

bonus Q: if the vertical 2x4s are called studs, what do you call the horizontal ones that get fastened to the floor ?

thx,

2.5 to 3.5 will suffice....red powder loads, be sure to get the pins with washers installed. A bead of adhesive helps seal the sill, also.

Use the 3-1/2" COATED nails. Make sure that they are coated/treated or galvanized, or the PT lumber will cause them to corrode. There is no need to use washers.

That depends on the concrete. I would suggest that you get several boxes of #2, #3, #4.... and return what you don't use. # 3 charge is about average for basements and PT 2x4 attachment.

They are called " plates".

Top = top plate

Bottom = bottom sill plate, or sole plate

Good luck on your project.

If the concrete is well cured, requiring the use of red loads ( #5 or #6 depending on manufacturer/style/caliber ), as in most remodeling scenarios, the use of the washered pins is recommended, and in fact required in some areas, even in new construction..........but then I can only refer to Southern Building Code here in Texas for recommendations, along with 42 years experience in the building trades.........didn't see any reference to using PT.........just 2X
