A powered grip that can engage and hold an item which includes a primary body member, an actuator dependent from the primary body member and a pair of spaced apart clamp jaws to move towards and away from each other. A force transmission mechanism is operatively located intermediate of the actuator and each of the clamp jaws to displace the clamp jaws relative to the primary body and that, through mechanical advantage, establishes a multiplication of the force of the actuator force at the clamp jaws. A force transmission mechanism geometry adjuster is provided to vary the spacing between the clamp jaws for any given operating force applied by the actuator, allow the pre-testing setting of the spacing between the jaws such that the range of force applied by the clamping jaws to the item to be tested is within a desired range.
