  • U-bolt torquing tool
    Patent number: 5555628
    Abstract: A method of determining the optimum torque for securing a U-bolt assembly calculated according to the formula T=UL.multidot.d.multidot.K.multidot.LF, where T is the optimum torque, UL is a calculated value for the ultimate tensile load of one U-bolt leg, d is the diameter of the threaded end of one U-bolt leg, K is a torque coefficient of friction associated with the U-bolt assembly, and LF is a chosen load safety factor. A tool used in securing the U-bolt assembly includes at least one surface having torquing indicia located thereon and a radius for testing the bend radius on the U-bolt. The torquing indicia includes U-bolt assembly designation data and a corresponding optimum torque value.
