" side member thickness and penetration into main member as follows:
TimberLok 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 Specification for Wood Construction (2005 NDS).
When using in critical applications, please consult a design professional or refer to our technical bulletins for
the proper spacing and fastening patterns.
The statement “Faster, Easier, Stronger than
