" high torque drill (18V cordless or higher), drive the HeadLok head flush to the surface. No predrilling
required when proper end and edge distances are maintained.
* SCL=Structural Composite Lumber (LVL,PSL and LSL)
** Wood species identified typically have average specific gravity similar to the values shown on this table.
All design values based on 1
1
⁄
2
" side member thickness and penetration into main member as follows: HeadLok 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). HeadLok design value calculations are based on independent lab
testing as outlined in ICC Acceptance Criteria AC233. All values have been reviewed and certified by a professional
engineer.
The statement “Faster, Easier, Stronger than
3
⁄
8
" lag screws” refers to the comparison of design shear values of
HeadLoks and
3
⁄

" lag screws.
A design professional should be consulted when making critical connections to ensure the proper number and location
of all fasteners meet national and local code requirements.
