Wood species identied typically have average specic gravity similar to the values shown on this table.

All design values based on 11⁄2" side member thickness and penetration into main member as follows: LedgerLok 2", Nails 10x diameter, Lags 8x diameter. Design values may be subject to adjustment factors (section 10.3 in NDS) based on conditions existing during installation as well as those expected during service life.

The lag screw and nail design values included in these tables are compiled directly from the 2005 National Design Specication for Wood Construction (2005 NDS).
