FastenMaster® TimberLok® Heavy Duty Wood Screws

The FastenMaster® TimberLok® Heavy Duty Wood Screw can replace 3/8" lag screws and enables you to complete wood-to-wood projects faster, easier and stronger. All design values based on 1-1/2" 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 2001 National Design Specification for Wood Construction (2001 NDS). All FastenMaster TimberLok Wood Screws should be installed using a high torque, 1/2" variable speed drill (at least 18V if cordless). Choose the proper length so that threads fully engage the second piece.
