Use of Nail Guns for Fixing Trussed Rafter Bracing

(December 2008) (First issue)

Question:

The gauge of the nails used in nail guns is less than that quoted in the NHBC Standards. Can these be used for fixing trussed rafter bracing?


Considerations:

  • NHBC Standards clause 7.2.9 asks for 3.35mm (10 gauge) x 65mm long galvanised nails – nails used in nail guns are not available to this specification.


Answer:

When nail guns are used, 3.1mm x 75mm long annular ring-shank nails are acceptable. They do not need to be galvanised.
