This SAE Information Report is provided as an advisory guide. Careful discretion as to application is recommended. The content has been presented as accurately as possible, but responsibility for its application lies with the user. It covers finishes applied to fasteners and related topics, corrosion resistance, lubricity, electrical grounding, ultraviolet light, and embrittlement. Table 1 lists these coatings and their properties so that finish selection can be reasonably made in accordance with known and anticipated fastener assembly applications. Application of protective coatings will affect fastener dimensions. This is especially critical for the thread fit of mating parts because the pitch diameter increases by four times the coating thickness. Explanation is covered in Section 5.
This test procedure is intended to provide a quality control method for checking torque-tension characteristics of non-prevailing torque type threaded steel fasteners 6 through 24 mm nominal diameters. Realistically, torque-tension relationships for specific individual fastener assembly joints will vary due to the different joint parameters. Tests using actual joint components will be required to determine accurate torque-tension values for those conditions. For the inch series version, see SAE J174.
This recommended practice covers methods for measuring, classifying, and specifying decarburization in the threaded section of hardened and tempered steel bolts, screws, studs, and similar parts. It is not intended to cover products which are specifically carburized to achieve special properties.

The Dryseal American Standard Taper Pipe Thread, the Dryseal American Fuel Internal Straight Pipe Thread and the Dryseal American Intermediate Internal Straight Pipe Thread covered by this standard conform with the American Standard ASA-B2.2. The Dryseal SAE-Short Taper Pipe Thread in this standard conforms with the Dryseal American Standard Taper Pipe Thread except for the length of thread, which is shortened for increased clearance and economy of material. The significant feature of the Dryseal thread is controlled truncation at the crest and root to assure metal to metal contact coincident with or prior to flank contact. Contact at the crest and root prevents spiral leakage and insures pressure-tight joints without the use of a lubricant or sealer. Lubricants, if not functionally objectionable, may be used to minimize the possibility of galling in assembly.

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.
