Apparatus and methods for threading a nut along a stud or similar elongate member include use of a contact member within a first orifice that engages the nut, and a torque transfer member within a second orifice that engages both the contact member and a power source, such as an air ratchet. Torque from the power source causes movement of the torque transfer member, which in turn causes movement of the contact member, thereby threading or unthreading the nut along the stud or other elongate member. The first orifice includes a through bore for accommodating passage of the elongate member, while the body of the apparatus can include ferromagnetic members for preventing loss of the nut and additional structures for limiting undesired movement of the power source or apparatus through contact. |
