<p>A hand-actuated bar clamp apparatus (10) is disclosed which provides a high level of holding power or force on a workpiece. The bar clamp (10) includes first and second jaws (12,14) that arc movably coupled to a bar (16). The first jaw (12) includes a drive lever (68) that engages the bar (16) and a trigger (18) that drives the drive lever (68) to move the bar (16) relative to the first jaw (12). A brake mechanism (20) is contained within the first jaw (12) to prevent it from moving in the opposite direction. The second jaw (14) includes a push-button release assembly (48) and a stop mechanism (45) actuated by the push-button release assembly (48). The stop mechanism (45) frictionally engages the second jaw (14) to the bar (16) when the second jaw (14) is not under load.
