1.1 本规范涵盖了尺寸0.125（#5）至2.000 in.的非铁内六角紧定螺钉、尺寸0.190（#10）至1.500 in.的方头紧定螺钉和直径0.125（#5）至0.750 in.的开槽无头紧定螺丝的要求，这些螺丝由海洋工业和美国海军中使用的多种非铁合金制成，但也可用于其他应用。建议不要使用铜基合金来防止机械部件旋转，例如锁定轴，因为合金的硬度较低。 某些合金或尺寸的固定螺钉或两者都不容易获得。在设计开发或预期采购之前，应联系制造商或供应商。 1.2 单位-- 以英寸磅为单位的数值应视为标准。本标准不包括其他计量单位。 注1: 规范的完整公制配套 F3042 将被开发——F3042M；因此，在本说明书中没有示出度量等价物。 1.3 本标准并不旨在解决与其使用相关的所有安全问题（如有）。 本标准的使用者有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。

1.1 This specification covers the requirements for nonferrous socket set screws sizes 0.125 (#5) through 2.000 in., square head set screws sizes 0.190 (#10) through 1.500 in., and slotted headless set screws 0.125 (#5) through 0.750 in. in diameter manufactured from a number of nonferrous alloys in use in the marine industry and the U.S. Navy subject to seawater wetting and salt atmosphere but that also may be used in other applications. It is recommended that copper-based alloys not be used in attempting to prevent mechanical components from rotating, such as locking shafts, because of the low hardness of the alloys. Some alloys or sizes or both of set screws may not be readily available. Manufacturers or suppliers should be contacted before design development or anticipated procurement. 1.2 Units— The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard. Note 1: A complete metric companion to Specification F3042 will be developed—F3042M; therefore, no metric equivalents are shown in this specification. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
