Framing & StructuralQuestion 301 of 700
For wood structural panel sheathing, how far should nails typically penetrate into the framing member to be effective?
a.Just past the panel face
b.Exactly the panel thickness
c.At least about 1 inch into the framing
d.The full length of the stud
Explanation
Fastening schedules expect roughly 1 inch or more of penetration into the supporting framing so the nail develops withdrawal and shear resistance. Barely reaching the framing or matching only the panel thickness leaves too little embedment; penetrating the full stud is neither possible nor required.
