<p>A fastener comprising an elongate main body, a cutting tip on one end of the body which enables the fastener to drill its own opening through a member to which the fastener will be attached, and a toggle pin pivotly attached to the main body and movable between a retracted position where the toggle is substantially in-line with the main body, and an extended position where the toggle has pivoted away from the main body, the construction and arrangement being that the fastener can drill its own hole through the member and can then be pushed through the member sufficiently to allow the toggle pin to move to the extended position at which stage the fastener is attached to the member and cannot be removed from the member.</p> |
