Each jaw of a vise has fasteners, typically two allen-headed bolts, mounted at its face and protruding therefrom. Removable faceplates define keyhole apertures that are complementary in size and spacing to the allen-headed bolts. The faceplates' keyhole apertures slip over the loosened bolts without removing the bolts from the jaws. Each removable faceplate is then secured to its jaw by tightening the bolts against the shoulders of the keyhole aperture at its narrower regions. A removable faceplate so affixed is quickly interchangeable while maintaining good alignment and strength in its installed position.
