This International Standard specifies the mechanical and performance properties for prevailing torque type steel hexagon nuts (including those with flange) when tested over an ambient temperature range of 10 C to 35 C . Properties will vary at higher and lower temperature.
It applies to prevailing torque type nuts with nominal thread diameters up to and including 39 mm; of triangular IS0 thread according to IS0 68; with diameter/pitch combinations according to IS0 261; with thread tolerances 6H according to IS0 965-2; with specific mechanical requirements; with dimensions as specified in product standards provided they make reference to this International
Standard; within the temperature range -50 C to +300 C for all metal type nuts; within the temperature range -50 C to +20 C for non-metallic insert type nuts.
It does not apply to nuts requiring special properties which may require special materials or coatings to improve weldability; corrosion resistance; performance outside the above specified temperature ranges. Prevailing torque performance decreases with increasing re-use. The nut user should consider the implications
of decreased performance prior to re-use.
