This Standard specifies the functional properties for prevailing torque steel nuts when tested at an ambient temperature range of +10 \u00b0C to +35 \u00b0C.<\/p>\n
\nIt includes a combined test method to determine the prevailing torque properties and the coefficient of total friction as the torque\/clamp force properties at the same time.<\/p>\n
\nIt applies to prevailing torque all metal type nuts and prevailing torque non-metallic insert type nuts (hereafter referred to as nuts):<\/p>\n
\n\u2014 with triangular ISO thread in accordance with JIS B 0205-1;<\/p>\n
\n\u2014 with diameter\/pitch combination in accordance with JIS B 0205-3;<\/p>\n
\n\u2014 with coarse pitch thread M5 to M39 or with fine pitch thread M8 \u00d71 to M39 \u00d73;<\/p>\n
\n\u2014 with thread tolerances in accordance with JIS B 0209-2;<\/p>\n
\n\u2014 with mechanical properties in accordance with JIS B 1052-2.<\/p>\n
\nPrevailing torque values specified in this Standard are based on laboratory test conditions.<\/p>\n
\nNOTE 1 Actual prevailing torques in practical application can vary.<\/p>\n
\nNOTE 2 Prevailing torque all metal type nuts conforming to the requirements of this Standard are used in applications ranging from -50 \u00b0C to +150 \u00b0C.<\/p>\n
\nNOTE 3 Prevailing torque non-metallic insert type nuts conforming to the requirements of this Standard are used in applications ranging from -50 \u00b0C to +120 \u00b0C.<\/p>\n
\nAt the temperature outside this range, the capability of functional properties (torque and clamp force, and prevailing torque properties) may be reduced (see Annex A).<\/p>\n
