    摘要： A torque nut or screw that allows the nut to be tightened to a preset maximum torque, but prevents excess tightening. The nut or screw includes inner and outer threaded elements that extend along the same axis. The outer threaded element is tapered with respect to the axis. The fastener includes an inner fastening member (7) having fastening threads (8) and an outer female member (10) that is rotatable by means of a spanner, a pair of pliers, a screw driver, or other tool. The female member is connected to the inner fastening member by a coupling (13) having a sufficient strength to transfer to the inner fastening member a torque of a magnitude for which the fastening device is designed. The outer female member (10) is designed to be released upon tightening of the coupling and rotated relative to the inner fastening member (7), but not until the predetermined torque is exceeded. The coupling between the outer female (10) and the inner fastening member (7) includes a conical screw coupling.

    摘要： The nut includes a first half having a short shank with an internal screw thread therethrough and an external screw thread on the short shank and a second half with a threaded bore. The internal thread has a first pitch and the external thread has a second screw pitch, the second and third screw pitches having different vertical lengths. The threaded bore includes a first section and a second section wider than the first section and the length of the short shank. The first section has a screw pitch equal to the first screw pitch and the second section has a third screw pitch slightly finer than that of the second screw pitch.
