Organization: JSA
Publication Date: 20 April 2011
Status: inactive
Page Count: 28
ICS Code (Nuts): 21.060.20
scope:

This Standard specifies the mechanical and performance properties for prevailing torque type steel nuts when tested over an ambient temperature range of 10°C to 35 °C.

This Standard includes the test method for determination of the coefficient of total friction as prevailing torque characteristics and clamping characteristics.

This Standard applies to the following prevailing torque all metal type nuts and prevailing torque non-metallic insert type nuts (hereafter referred to as "nuts"):

a) with triangular ISO thread according to JIS B 0205-1;

b) with diameter/pitch combinations according to JIS B 0205-3;

c) with coarse pitch thread M3 to M39 and mechanical properties according to JIS B 1052-2;

d) with fine pitch thread M8 x 1 to M39 x 3 and mechanical properties according to JIS B 1052-6;

e) within the temperature range of -50°C to + 150 °C for prevailing torque all metal type nuts;

f) within the temperature range of -50°C to + 120 °C for prevailing torque non-metallic insert type nuts.

NOTE: The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows:

ISO 2320: 2008 Prevailing torque type steel nuts-Mechanical and performance properties (MOD)

The symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/ lEC Guide 21-1.
