Thor Helical nails for timber frame fixing and batten fixing to Thermalite, Celcon, Xella, or to other aircrete blocks without need to pre-drill, plug or screw. The fixings spiral form induces rotation as each 'AirTwist'™ helical nail is hammered in, delivering a self tapping hammer-fix connection.

Reliability of performance stems from the consistent holding power of the helical fastener along the full length of its precisely formed and patented helix.

The new Thor 'Air Twist'™ fastening system offers effective frame fixing and batten fixing with remarkable speed and great simplicity, as timber elements are anchored to autoclaved aerated concrete (Thermalite, Celcon, Xella, etc) using a neat single action roto-hammer setting tool.

Replacing conventional wall plugs, screws and hammer-fix products the rapid-drive AirTwist™ spiral nails deliver extraordinary holding power, offering significant performance and cost benefits over alternative timber to masonry fasteners.

AirTwist helical twist nails can also be driven into brick, stone and concrete via a small pilot hole. Low-cost SDS drive adapters facilitate rapid fastening rates that allow wall plates or mud sills to be anchored to concrete or masonry in record time.

These versitile headless helical fixings are also well suited as a quick fix, high performance timber-to-timber fastening.

Launched in October 2008 the AirTwist™ is already attracting interest from specifiers, house builders and aircrete block manufacturers worldwide.
