标准摘要
[中文适用范围]： 1 范围 本文件规定了具有公制粗牙螺纹M5至M39、产品等级为A和B的钢和不锈钢六角高螺母（全金属）的特性，这些螺母具有保持扭矩特性。 注：这些螺母的设计整体高度h min = m min（如ISO 898-2和ISO 4033中对于2型螺母所规定的）加上保持扭矩特性。h max是基于h min确定的，因此公差（h max - h min）不遵循ISO公差等级系统（IT系统）。扳手高度m w,min对应于1型螺母规定的值。在某些情况下，如有其他规格要求，性能等级和不锈钢牌号可从ISO 898-2或ISO 3506-2中选择。 [外文原描述]： This document specifies the characteristics of prevailing torque (all metal) hexagon high 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 heigth h min = m min (as specified in ISO 898-2 and ISO 4033 for style 2) 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). The wrenching height m w,min corresponds to the values specified for style 1. 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.
