Product Description
Flange lock nuts are reusable but only for a limited number of times because the prevailing torque declines each time the nut is used. Always follow the manufacturer's recommendations regarding nut reuse, thread lubricants and torque values. Do not apply standard torque values to prevailing torque lock nuts because the joint may not be tightened to the correct clamping force due to the additional friction of the locking element.
It is possible that the locking feature, which consists of deformed threads, may damage the threads of the nut or bolt. The possibility is reduced when the strength grades of the nut and bolt are compatible. For example, Grade G nuts are suggested for use with bolts having a specified minimum ultimate tensile strength of not less than 120, nor greater than 150 ksi. The chance of damage is greatest if the hardness of the mating fastener is vastly different; for example, using a non-heat treated low carbon steel bolt or screw with a heat treated nut.
