The TetraGrip™ fastening system is a technological breakthrough in subfloor fixing. With its dedicated pneumatic coil nailer, the TetraGrip fastener drives like a nail and holds like a screw.

The patent pending barbed helical shank design rotates as it is driven to provide the withdrawal strength of a screw with the speed of installing a nail (three times faster than screwing) and without the nail induced squeaks! The fasteners are collated on the time proven and reliable Duo-Fast plastic coil.
