• Stronger design shear values than 3/8" lags.
• Nationally recognized testing and code approvals.
• Sharp point and aggressive thread penetrate the densest woods without predrilling.
• Unique tapered head countersinks easily into wood for flush appearance.
• Variety of lengths, from 21/2" to 10", to match every application.
• Proprietary three step coating process protects against corrosion, even in pressure treated wood. ACQ Approved.
• Free bit in every package.

The FastenMaster TimberLok 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. 

TimberLok Comparative Data The statement Faster, Easier, Stronger Than 3/8" Lag Screws relates to the comparison of design shear values of TimberLoks and 3/8" lag screws. The Professional Engineer (PE) is responsible for designing all connections, which include the number and location of all fasteners to meet the national and local code requirements. All minimum end, edge and spacing distances of the TimberLok should follow minimums set forth in ICC ESR-1078. (see www.fastenmaster.com) This report should be reviewed thoroughly when designing connections. Note: Photographs on this package showing TimberLok usage should not be used as a reference for fastening patterns. For complete design values and engineering data, available through ICC-ES, see report ESR-1078 at www.icc-es.org.

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).
