标准摘要
[中文适用范围]： 本文件规定了具有非金属嵌件的普通扭矩六角螺母（钢和不锈钢材质，公制粗牙螺纹M3至M39，产品等级A和B）的特性。注：这些螺母的设计总高度等于mmin（如ISO 898-2和ISO 4032中规定的样式1）加上扭矩保持特征。对于非金属嵌件，扭矩保持特征的高度（hmax – mmin）在相同直径下对普通螺母、高强度螺母和薄型螺母是相同的。尺寸D < M5且设计原则符合样式1的螺母在附录A中有所规定。在某些情况下，如需其他规格，可从ISO 898-2或ISO 3506-2中选择性能等级和不锈钢牌号。 [外文原描述]： This document specifies the characteristics of prevailing torque hexagon regular nuts (with non‑metallic insert), in steel and stainless steel, with metric coarse pitch thread M3 to M39, and with product grades A and B. NOTE These nuts are designed with an overall height equal to m min (as specified in ISO 898-2 and ISO 4032 for style 1) plus the prevailing torque feature. The height of the prevailing torque feature ( h max – m min ) for the non-metallic insert is identical for regular, high and thin nuts for a given diameter. Nuts with sizes D < M5 and design principles in accordance with style 1 are specified in Annex A. If in certain cases other specifications are requested, property classes and stainless steel grades can be selected from ISO 898-2 or ISO 3506-2.
