Product Questions
-
Can I still get 16" Headlok screws?
Unfortunately, Fastenmaster recently discontinued the 9-1/2", 15", 16", and 18" Headlok screws.
-
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.
