1.1 本规范涵盖了标称直径为0.060至2英寸的淬火和回火合金钢套筒定位螺钉（SSS）的要求。硬度为45至53 HRC。 1.2 这些固定螺钉仅用于压缩应用，通常不进行脆化试验。对于拉伸应用，请咨询制造商以了解合适的合金和硬度。 1.3 以英寸-磅为单位的数值应视为标准值。本标准不包括其他计量单位。 注1: 规范的完整公制配套 F912 已开发- F912M ; 因此，本规范中未显示公制等效值。 1.4 危险声明仅适用于试验方法章节 11 符合本规范的要求。 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）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》中确立的国际公认标准化原则制定的。

1.1 This specification covers the requirements for quenched and tempered alloy steel socket-set screws (SSS) in nominal diameters 0.060 through 2 in. having hardnesses 45 to 53 HRC. 1.2 These set screws are intended for compression applications only and are not customarily subjected to embrittlement tests. For tensile applications, consult with the manufacturer for proper alloy and hardness. 1.3 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 F912 has been developed— F912M ; therefore, no metric equivalents are shown in this Specification. 1.4 The hazard statement pertains only to the test method section, Section 11 of this specification. 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 and health practices and determine the applicability of regulatory limitations prior to use. 1.5 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.
