自挤螺钉

[中文适用范围]： 该文件已被宣布为“稳定”，并且将不再接受货币定期审查。用户负责验证参考资料和持续适用性或技术要求。新技术可能存在。该 SAE 标准涵盖了适用于一般工程应用的滚丝螺钉的要求。 （“螺纹滚压”螺钉的性能超出了其他标准类型自攻螺钉通常预期的性能。） [外文原描述]： This SAE Standard covers requirements for thread rolling screws suitable for use in general engineering applications. (It is intended that "thread rolling" screws have performance capabilities beyond those normally expected of other standard types of tapping screws.)NOTE—The performance requirements covered in this document apply only to the combination of laboratory conditions described in the testing procedures. If other conditions are encountered in an actual service application (such as different materials, thicknesses, hole sizes, etc.), values shown herein for drive torque, torque-to-clamp load, and proof torque may require adjustment.Cross Reference: ANSI/B18.6.4,J478,J78_202107,MIL-STD-105D
