The GWZ fully threaded screw is ideal for fixing timbers in place and repairing damaged or weakened members. This fully threaded connector differs from a traditional screw with smooth shank in that it provides significantely increased performance because much more thread is embeded in the timber.
The notched tip cuts the fibers of the timber and makes the GWZ a self-tapping timber screw: reduced splitting and improved edge distancing even without pre-drilling.
Every box comes with a TX bit and we are proud of the fit of our specialty engineered bits.
The GWZ is made of zinc plated high stength carbon steel that combines structural performance with ductility.
