No Predrilling. Stronger than 3/8" Lags!
The FMTLOK04-250 (Box of 250) 4" 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.
