- This Standard covers general and dimensional data pertinent to the various types of screw and captive washer assemblies, otherwise known as SEMS. SEMS products may include screws, tapping screws, or bolts in sizes No. 0 through 1⁄2 in. diameters in various grades and materials. The word SEMS is recognized in the United States as a generic term applicable to screw and washer assemblies. Also included in this Standard is Nonmandatory Appendix A illustrating the relative proportions of plain and conical washer SEMS. NOTE: The word lock, which appears in the names of products in this Standard, is a generic term historically associated with their identification and is not intended to imply an indefinite fixity in attachments where the fasteners are used. 本标准涵盖了与各种类型的螺钉和外加垫圈组件（也称为SEMS）相关的一般和尺寸数据。SEMS产品可能包括各种等级和材料的直径为0至1⁄2英寸的螺钉，攻丝螺钉或螺栓。SEMS一词在美国被认为是适用于螺钉和垫圈组件的通用术语。本标准还包括非强制性附录A，说明了普通和锥形垫圈SEMS的相对比例。 注：本标准中产品名称中出现的锁字是一个通用术语，历史上与其标识相关，并不意味着在使用紧固件的附件中无限固定。
