Prevailing torque type steel nuts - Mechanical and performance properties

inactive
Organization: CEN
Publication Date: 1 November 2008
Status: inactive
Page Count: 26
ICS Code (Nuts): 21.060.20
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 M8×1 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.
