The present invention is directed towards temporary fasteners (''tack'' fasteners) comprising a housing body, a collet body and a translatable central body. The housing body is configured to receive both a portion of the collet body and a portion of the translatable central body wherein another portion of the collet body and a portion of the housing body provide work piece contacting surfaces. Translation of the central body through an internal bore of the collet body causes displacement and/or convergence of radially displaceable portions of the collet body. Such translation may be generated by rotation of the central body relative to the collet body. Sympathetic rotation of the collet body is substantially prevented by a two part anti-rotation feature such as a non-circular bore within the housing body complementary to a non-circular portion of the collet body, or extending features from the collet body interacting with slots or grooves formed in the housing body.
