Abstract:
A torque-limiting device may include a shaft extending axially through upper and lower shanks, a spring, and a nut to an end opening of a handle. The upper and lower shanks may be under a force from the spring and further configured to selectively engage within a predetermined torque limit and disengage at above the predetermined torque limit. Accordingly, the shaft may receive torque up to the predetermined limit as provided by a user operating a handle of the torque-limiting device. The torque-limiting device may be disposable, reusable, economical, and have high torque capabilities. The shaft may be of a plastic material and include a lumen extending there through, and through which a variety of devices and materials may be delivered to a workpiece.
