Abstract
A threaded fastener including a shank extending along an axis away from an enlarged head to a tip. A thread extends in a helix around the shank from the tip of the shank towards the enlarged head. A driving recess on a top surface of the enlarged head receives a tool for driving the fastener in a rotational manner around the axis of the shank. Cutter teeth are formed on a lower surface of the enlarged head. The fastener may be assembled with a hard composite non-wood material decking and a supporting metal I-beam.

A threaded fastener comprising:
- a shank extending along an axis away from an enlarged head to a tip,
- a thread extending in a helix around the shank from the tip of the shank towards the enlarged head,
- a driving recess on a top surface of the enlarged head arranged to receive a tool to allow a driving of the fastener in a rotational manner around the axis of the shank, and
- cutter teeth formed on a lower surface of the enlarged head,
- the cutter teeth each comprising a ridge extending radially outwardly from the shank to a peripheral edge of the enlarged head,
- the thread is arranged on the shank so that the fastener is advanced upon a rotation of the fastener around the axis in a first rotational direction and each ridge comprises two side walls angled relative to the axis and meeting at an apex, the apex leading the two side walls in the rotational direction of advance of the fastener.
