This SAE Information Report is provided as an advisory guide. Individual application discretion is recommended. The content has been presented as accurately as possible, but responsibility for its application lies with the user. The document covers a number of the variables in the torque-tension relationship: friction, materials, temperature, humidity, fastener and mating part finishes, surfaces, and the kind of tightening tools or equipment used. Also described in this document is the torque management required to achieve satisfactory fastened joint tightening. This guide is limited in application to clearance fit threads, such as the common 6g/6H class of fit. Other thread types including interference fit, mechanical locking, prevailing torque, or forms other than ISO-metric may apply to some aspects of this standard but are not specifically covered.

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.

This SAE Recommended Practice covers installation and inspection methods for fasteners which are tensioned using Tension Indicating Washers (TIWs) as a means to ensure that adequate tension is developed in mechanically fastened joints. Figure 1 depicts a typical TIW, and Figure 2 depicts a fastener assembly with a TIW before and after tensioning.

This SAE Recommended Practice defines, illustrates, and specifies allowable limits for various types of surface discontinuities that may occur or become apparent during the manufacture and processing of bolts, screws, and studs which are primarily intended for use in automotive assemblies subjected to severe dynamic stresses and necessitating use of high strength fasteners having appropriate fatigue-resistant properties.
This SAE Standard covers the dimensional and general specifications, including performance requirements, for carbon steel self-drilling tapping screws suitable for use in general applications having point Styles 2, 3, 4, and 5. It is the objective of this document to ensure that carbon steel self-drilling tapping screws, by meeting the mechanical and performance requirements specified, shall drill a hole and form or cut mating threads in materials into which they are driven without deforming their own thread and without breaking during assembly.
