紧固件.热浸镀锌涂层

[中文适用范围]： 本国际标准规定了用于 M8 至 M64 粗螺纹钢紧固件的热浸旋镀锌涂层的材料、工艺、尺寸和一些性能要求，以及螺栓、螺钉和螺柱性能等级高达 10.9 级和 12 级的性能要求。 坚果。 不建议对直径小于 M8 和/或螺距低于 1.25 mm 的螺纹紧固件进行热浸镀锌。 注：需要注意的是，与螺纹 M8 和 M10 的超大尺寸攻丝螺母相比，其极限拉伸载荷和保证载荷下的应力以及带有 M8 和 M10 螺纹的小尺寸螺纹螺栓和螺钉的极限拉伸载荷和保证载荷比值分别在 ISO 898-2 和 ISO 898-1 中规定，并在附录 A 中规定。 它主要涉及螺纹钢紧固件的旋压热浸镀锌，但也可适用于其他螺纹钢零件。 本国际标准给出的规范也适用于非螺纹钢零件，例如垫圈。 [外文原描述]： ISO 10684:2004 specifies material, process, dimensional and some performance requirements for hot dip spun galvanized coatings applied to coarse threaded steel fasteners from M8 up to and including M64 and for property classes up to and including 10.9 for bolts, screws and studs and 12 for nuts. It is not recommended to hot dip galvanize threaded fasteners in diameters smaller than M8 and/or with pitches below 1,25 mm. ISO 10684:2004 primarily concerns the spun hot dip galvanizing of threaded steel fasteners, but it may also be applied to other threaded steel parts. The specifications given in this document may also be applied to non-threaded steel parts such as washers.
