专家解读视频
Describes general dimensions and tolerances of prevailing-torque type nuts with ISO metric threads in diameters from 3mm to 36mm. Mechanical properties and performance requirements are given only for steel nuts, with or without non-metallic inserts, e.g., nylon, not to be used for special applications requiring weldability, corrosion resistance or ability to withstand temperatures above 300 degrees C (120 degrees C for nuts with non-metallic inserts) or below -50 degrees C. Two nut heights are given, designated 'normal' and 'high' respectively. Either normal or high nuts, with or without non-metallic inserts, may be supplied.
