This section applies to effective torque type all-metal lock nuts and non-metal insert lock nuts that meet the following requirements.
--- Ordinary thread conforming to GB/T 192 regulations;
--- A combination of diameter and pitch in accordance with GB/T 193;
--- Thread specifications M3 ~ M39, mechanical properties comply with GB/T 3098.2;
--- Thread specification M8 × 1 ~ M39 × 3, mechanical properties conform to GB/T 3098.4;
--- The working temperature range of effective torque type all metal lock nut is -50 ℃ ~ 150 ℃;
Note 1.See Chapter 7, paragraph 3.
--- The operating temperature range of effective torque type non-metallic insert lock nut is -50 ℃ ~ 120 ℃.
Note 2.See Chapter 7, paragraph 4.
