标准摘要
[中文适用范围]： 本文件规定了具有预紧扭矩（全金属）的六角标准螺母的特性，该螺母采用钢和不锈钢制造，公制粗牙螺纹尺寸为M5至M39，产品等级为A和B。注：这些螺母的设计整体高度hmin = mmin（如ISO 898-2和ISO 4032中规定的样式1）加上预紧扭矩特性。hmax是基于hmin确定的；因此，公差（hmax – hmin）不遵循ISO公差代码系统（IT系统）。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 (all metal) hexagon regular nuts, in steel and stainless steel, with metric coarse pitch thread M5 to M39, and with product grades A and B. NOTE These nuts are designed with an overall height h min = m min (as specified in ISO 898-2 and ISO 4032 for style 1) plus the prevailing torque feature. h max has been established in function of h min ; therefore, the tolerance ( h max – h min ) does not follow the ISO code system for tolerances (IT system). 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.
