The patented triangular thread tip, developed by our company, can expand the opening width when driving in and help reduce driving torque. This screw can be used on timber-to-timber connections and over-rafter insulation systems, and it can also greatly improve work efficiency when using high-density wood building materials or engineered wood
* The patented triangular thread tip can effectively expand the hole, reduce driving torque, and save labor.
* Knurl threads can extend the effect of hole expansion, reduce the friction on the screw shank, and reduce the peeling of surface coating.
* A leading international standard of distortion.
