FastenMaster TimberLOK Wood Screws allow for quick and easy installation for a variety of wood framing uses. TimberLOK works without needing a pre-drilled pilot hole, and its self-countersinking design ensures the screw heads will sink below the surface of the wood and nothing sticks out above. Commonly used for rafter and truss to top plate connections, TimberLOK screws come in a variety of lengths & packaging sizes and can be used for various applications.

Features and Benefits:
• Requires no pre-drilling
• Self-countersinking design provides a flush installation
• Removable and reusable
• Greatly reduced labor time and lower cost versus lag bolts
• Engineered for increased strength, performance, and holding power
• Corrosion-resistant (ACQ approved)
• IBC/IRC code compliant (ICC-ES ESR-1078)
• Free bit to match hex heads in every package

Product Uses & Applications:
TimberLOK is available in a variety of lengths and packaging sizes for applications such as attaching rafter or trusses to the top plate, landscape timbers, fences, decks, headers, stair stringers, and more.

Performance:
TimberLOK is guaranteed not to corrode or rust for the lifetime of the project (when used properly according to the installation instructions). The fastener coating has been tested in wood treatment chemicals, such as ACQ, and is found to provide equal protection to code-approved hot-dipped galvanized coatings. TimberLOK is not recommended for use within 1000 feet of saltwater, and stainless steel fasteners are recommended for use in those cases.

Installation Instructions:
Install TimberLOK perpendicular to the log using a high torque, 1/2" variable speed drill (18V if cordless). Countersink the TimberLOK a minimum of 1/4". Choose the proper length so that threads fully engage the main member or bottom piece. Bring washer head flush to wood surface or countersink head flush.

For rafter or truss to top plate applications, the 6" TimberLOK is easily installed at a 15-30° angle. For detailed installation instructions, including fastening requirements, please refer to our Rafter or Truss to Top Plate technical bulletins (linked at bottom of More Info section). These instructions are included in all box and bucket packaging as well as being available for download from our website. A design professional should be consulted for all other critical connections, to include the number and location of all fasteners to meet national and local code requirements.

Sample Applications:

Truss/Rafter to Top Plate Connection
The 6" TimberLOK® can be used in many cases as a replacement for hurricane ties used to resist uplift and lateral loads on trusses and rafters attached to the top plates of the wall. For instructions and additional technical information, consult the Truss and Rafter to Top Plate Technical Evaluation Report, TER No. 1105-02, available at www.FastenMaster.com.

Gable Truss Connection and Drag Truss Connection
The 4" and 6" TimberLOK® can be used in gable and drag trusses to resist the uplift and shear forces from wind and seismic events. The current methods for making these connections include the use of angled connectors and multiple nails. In most cases, the TimberLOK fasteners can be placed at equal or greater spacing than the ties they are replacing. For instructions and additional technical information, consult the Gable Truss to Top Plate Technical Evaluation Report, TER No. 1304-02, or Drag Strut to Wall Plate Technical Evaluation Report, TER No. 1306-01, available at www.FastenMaster.com.

Shear Wall Connection
The 4", 6" and 8" TimberLOK® can be used in shear wall or portal frame construction to resist the shear forces exerted on the top and bottom wall plates to the adjacent rim. Typically, the shear being transferred between these plies can only be accomplished through the use of excessive nail patterns. The increased strength of the TimberLOK fastener allows for greater connection strength with significantly less fasteners. For instructions and additional technical information, consult the Wall to Rim Joist Technical Evaluation Report, TER No. 1306-05, available at www.FastenMaster.com.

Product Questions

  • How are these different from the FastenMaster Olylog screws?

    Timberlok and Olylog screws have the same specifications. The only difference is Olylog is packaged in higher quantities with log home construction in mind and Timberlok is packaged in lower quantities intended for more conventional use.
