Fasteners

Proper fasteners are a critical component in a sound wood frame structure. To ensure successful installations of its connectors, USP offers a full
range of structurally-rated nails. All galvanized nails supplied by USP are Hot-dipped for greater corrosion resistance. Any USP connector requiring
a NA16D-RS or NA20D nail is shipped with the nails attached to the connector in convenient poly bags.
Finish: See chart
Materials: ASTM A 123; ASTM A 153 (HDG)
Installation:
• Allowable shear values assume nail embedment into the wood of the entire nail or 10 nail diameters (whichever is less). Otherwise, the nail must
be embedded at least 6 nail diameters, with the load reduced using the equation below:
Reduced Load =
Published Load x Actual Penetration
Nail Diameter x 10
• Load reductions may occur if nails are used other than those specied. See the chart Optional Nails for Face Mount Hangers on page 21
for load reduction factors regarding nail substitutions.
• For pneumatic nail use, see Installation Notes on page 19 and reference USP’s technical bulletins.
