See full text

A dual drive bit is formed as an integral body which includes a drive end which is shaped and configured for engagement with a fastener and an opposite driven end. The driven end includes an internal socket and an external, shaped surface enabling the drive bit to be driven by engaging the internal socket by a socket drive or externally by a wrench. Intermediate the drive end and the driven end is an intermediate or medial section of the body which includes a flange that extends at least in part radially beyond the circumference of the driven end to enable a user to positively engage the driven end and force it axially into engagement with a fastener.
