Beauty and safety

No more screw heads with an imperfect appearance and alignment, dangerous to bare feet, and no more splitting and cracking of the wood at the ends of boards.

Cobra fasteners are removable

A special bit is provided to screw down (or unscrew) between the two boards. Thus, Cobra fastener screw is removable between the boards (see board replacement video).
A considerable advantage to replace a twisted board without having to remove the whole deck.
