Product Questions

  • What's the difference between the HeadLOK screw and the TimberLOK screw?

    The head is the biggest difference between the Headlok and Timberlok screws.  The Headlok has a flat head that lays flat on top of the surface of the board.  The Timberlok has a hex head that countersinks into the board.  Other attributes such as the shank diameter, coating, and thread length are the same.
