本文件规定了钢制和不锈钢制六角薄螺母（0型）的特性，公制细牙螺纹为8 mm至64 mm，产品等级为A和B。 用作防松螺母的薄螺母应与普通螺母或高螺母组装在一起。 警告——与普通螺母或高螺母相比，薄螺母（0型）的承载能力降低，并且其设计不提供螺纹剥离阻力（见ISO 898-2）。 如果在某些情况下要求其他规范，不锈钢等级和性能等级可从ISO 3506-2中选择。

This document specifies the characteristics of hexagon thin nuts (style 0), in steel and stainless steel, with metric fine pitch thread 8 mm to 64 mm, and with product grades A and B. Thin nuts used as jam nuts are to be assembled together with a regular or high nut. WARNING — Thin nuts (style 0) have a reduced loadability compared to regular nuts or high nuts, and are not designed to provide resistance to thread stripping (see ISO 898-2). If in certain cases other specifications are requested, stainless steel grades and property classes can be selected from ISO 3506-2.
