INSTALLATION PROCEDURE
LedgerLok should be installed using a high torque,
1

" variable speed drill (at least 18V if cordless).
Choose the proper length LedgerLok so that threads fully engage the main member (i.e., rim joist). Bring
washer flush to side member – do not countersink.
* 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

" 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 Specification for Wood Construction (2005 NDS).
For correct fastening patterns and complete installation procedures when attaching the deck ledger to
rim joist, consult our Deck Ledger to Rim Joist Technical Bulletin at www.FastenMaster.com. In some ledger
board connections, LedgerLok may not be a one-to-one replacement for

For use of LedgerLok in non-ledger applications, please consult a design professional for designing all
connections, which include the number and location of all fasteners to meet the national and local code
requirements.
