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.) NOTEThe 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.
This standard has been stabilized because it covers a mature product that is unlikely to change in the future. The same technical information is now covered in ASME B18.6.3 – 2010 and later and should be referenced for all future designs.
