Robust nose torque-limiting device

摘要: A torque-limiting driver is disclosed, having a handle, body, assembly and work-piece engaging tip. The includes an upper lower shank that have plurality of teeth circumferentially spaced. vertical face, inclined flat peak. There spring for applying pressure across the with multiple washers interposed between shaft spring. In some instances, there round-square drive arched catches preselected radii to assure operation over certain cycles at selected torque reduce nose cone damage breakage predetermined measurement inch-pounds torque.
