  • Torque-limiting bolt-and-nut assembly
    Patent number: 6739631
    Abstract: A torque-limiting bolt-and-nut assembly is provided for actuating a pipe-pressing member in order to secure two pipe ends together. The bolt includes a threaded shank, a secondary drive head, and a shearable drive head designed to be sheared-off by a torque exceeding a predetermined value. A recess is formed between the shearable drive head and the second drive head. The nut is mounted on the shearable drive head and is configured for transmitting torque to the shearable drive head from a manual tool. A nut includes a connection structure extending into the recess for resisting dislodgement of the nut from the bolt. The shearable drive head has at least four sides, all of the sides being of equal length, and the number of the sides being an even number.
