This International Standard specifies the functional properties for prevailing torque type steel nuts when tested at an ambient temperature range of +10 °C to +35 °C. It includes a single test to determine the prevailing torque properties and/or the torque/clamp force properties.It applies to prevailing torque all metal type nuts and prevailing torque non-metallic insert type nuts:a)with triangular ISO thread according to ISO 68-1;b)with diameter/pitch combination according to ISO 261 and ISO 262;c)with coarse pitch thread M5 to M39 or with fine pitch thread M8´ð1 to M39´ð3;d)with mechanical properties according to ISO 898-2;NOTE 1All metal type nuts conforming to the requirements of this International Standard have been used in applications ranging from 50 C to +150 C.NOTE 2Non-metallic insert type nuts conforming to the requirements of this International Standard have been used in applications ranging from 50 C to +120 C. WARNING Temperatures outside the ambient temperature range can influence the functional properties (torque/clamp force and prevailing torque properties), see Annex A.
