标准摘要
[中文适用范围]: 本文件规定了具有非金属插入物的六角薄型螺母(防松螺母)的特性,其材料为钢和不锈钢,公制粗牙螺纹尺寸为M3至M39,产品等级为A和B。注:这些螺母的总高度等于mmin(如ISO 898-2和ISO 4035中规定的样式0)加上防松功能的高度。对于非金属插入物,防松特征的高度(hmax – mmin)在相同直径下,对普通螺母、高螺母和薄螺母是相同的。尺寸D < M5且符合样式0设计原则的螺母在附录A中有规定。警告——薄螺母(样式0)的承载能力较普通或高螺母有所降低,它们并未设计用于防止螺纹剥离(参见ISO 898-2)。在某些特定情况下,如果需要其他规格,可从ISO 3506-2中选择不锈钢牌号和性能等级。 [外文原描述]: This document specifies the characteristics of prevailing torque hexagon thin 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 4035 for style 0) 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 0 are specified in Annex A. WARNING — Thin nuts (style 0) have a reduced loadability compared to regular or high nuts, they 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.
