Scope

This part of GB/T 3098 specifies the mechanical and working properties of effective torque type steel lock nuts when tested at an ambient temperature of 10°C to 35°C. Include individual tests to determine effective torque performance (working performance) and/or torque-clamping force performance. This section applies to all-metal lock nuts and non-metallic insert lock nuts that meet the following effective torque requirements: —— Ordinary threads that meet the requirements of GB/T 192; —— Combinations of diameter and pitch that meet the requirements of GB/T 193 ; ——Thread size M3～M39×3, the mechanical performance complies with GB/T 3098.2; ——Thread size M8×1～M39×3, the mechanical performance complies with GB/T 3098.4; The working temperature range is -50℃～+150℃; ——The working temperature range of effective torque type non-metallic insert lock nut is -50℃～+120℃.
