标准摘要
[中文适用范围]： 本文件规定了具有非金属嵌件的钢和不锈钢六角厚螺母（细牙螺纹，直径8 mm至39 mm）的产品特性，产品等级为A和B。注：这些螺母设计为整体高度等于mmin（如ISO 898-2和ISO 8673中规定的风格1）加上防松扭矩特性。对于给定直径的普通、高强度和薄型螺母，非金属嵌件的防松扭矩特性高度（hmax – mmin）是相同的。如在某些情况下需要其他规格，可从ISO 898-2或ISO 3506-2中选择相应的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 fine pitch thread 8 mm to 39 mm, 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 8673 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. 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.
