Scope: This International Standard specifies the mechanical and performance 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 (performance properties) and/or the torque/clamp force properties. This International Standard 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 M3 to M39 and mechanical properties according to ISO 898-2; d) with fine pitch thread M8xl to M39~3 and mechanical properties according to ISO 898-6; e) within the temperature range of-50 ~C to +150 ~C for prevailing torque all metal type nuts; NOTE 1 See Clause 7, paragraph 3. f) within the temperature range of-50 ~C to +120 ~C for prevailing torque non-metallic insert type nuts. NOTE 2 See Clause 7, paragraph 4.
