ABSTRACT:
A vice jaw support apparatus provides a novel support system for securement of splined and threaded work pieces within vice grippers or jaws. In a preferred form, the apparatus is formed of a polyethylene or other similar resilient material. In a preferred form, the apparatus defines a pair of plastic bodies which are interconnected by integral web portions joining the two bodies on opposite sides. The web portions are disposed for deforming outwardly when the two body portions are moved towards each other within the vice jaws. Each body contains a flange portion whereby the apparatus may be supported on the upper surfaces of associated vice jaws.
