The TLL and TBS washer head screws are ideal for fastening and pulling timber members tight. The big diameter model offers great shear resistance in structural applications and the large head keeps everything where it should be.
These screws' feature an asymmetric “umbrella” thread that provides them with better pull-out. The notched tip cuts the fibers of the timber and makes the TLL and TBS a self-tapping timber screw: reduced splitting and improved edge distancing even without pre-drilling.
Every box comes with a TX bit. We put a lot of effort in engineering a great BIT with a great FIT.
The screw is made of zinc plated high stength carbon steel that combines structural performance with ductility. The EVO version comes with extra corrosion resistance coating for outdoor applications and Pressure Treated Lumber.
Use this for: indoor and dry & covered outdoor applications, non-treated lumber, timber frame, log building
