This SAE 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.

This SAE Recommended Practice defines, illustrates, and specifies allowable limits for various types of surface discontinuities that may occur during the manufacture and processing of bolts, screws, and studs in sizes through 24 mm or 1 in diameter inclusive with lengths to 150 mm or 6 in inclusive, having specified minimum tensile strengths of 900 MPa or 120 000 psi and greater, which are primarily intended for use in automotive assemblies.

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 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 mechanical and material requirements for three grades of steel nuts suitable for use in automotive and related engineering applications, in sizes 1/4 to 1-1/2 in, inclusive, and with dimensions conforming with the requirements of the latest issue of SAE J482 or ASME B18.2.2, except for machine screw nuts which are not covered in this standard. This document does not include limits for surface discontinuities. Where usage requires such control, limits may be specified separately. For sizes 1/4 through 1 in, this may be done by the statement: “Surface discontinuities shall not exceed the limits specified in ASTM F812/F812M.”

This SAE Standard covers the mechanical and material requirements for inch-series steel bolts, screws, studs, screws for sems1, and U-bolts2 used in automotive and related industries in sizes to 1-1/2 in. inclusive. The term “stud” as referred to herein applies to a cylindrical rod of moderate length threaded on either one or both ends or throughout its entire length. It does not apply to headed, collared, or similar products which are more closely characterized by requirements shown herein for bolts.

This SAE Recommended Practice defines, illustrates, and specifies allowable limits for various types of surface discontinuities that may occur during the manufacture and processing of bolts, screws, and studs in sizes through 24 mm or 1 in diameter inclusive with lengths to 150 mm or 6 in inclusive, having specified minimum tensile strengths of 900 MPa or 120 000 psi and greater, which are primarily intended for use in automotive assemblies.

These specifications cover the mechanical and chemical requirements, and surface discontinuities limits for carbon steel solid rivets used in automotive and other related industries.

This SAE Recommended Practice covers the use of preferred bolt and capscrew sizes, wherever applicable, on construction and industrial machinery to ease serviceability. Designers, in their efforts to determine the proper fastener for heavy equipment, sometimes overlook the practical aspects of serviceability. When a particular component requires frequent service, it is much faster and easier for the serviceman to work with common size, easily distinguished bolts and capscrews which require a minimum of tools. Section 4 lists eight diameters of recommended bolts and capscrews, some of which can be found in any hardware store, require only standard tools, are easy to distinguish, and at the same time cover proof loads from 1043 kg (2300 lb) on up at convenient intervals. While some applications may require other sizes and/or fine threaded fasteners for greater camping forces and/or area restrictions, the convenience of UNC threads in the sizes indicated is preferred wherever possible.

Included herein are the detailed general and dimensional specifications applicable to high hex nuts. All general specifications not shown here shall conform with those applicable to hex thick nuts and hex thick slotted nuts appearing in ASME B18.2.2. High hex nuts are primarily intended for use in automotive and other ground-based vehicles and industrial equipment where a long length of hexagon is required for wrenching purposes.

Included in this SAE Recommended Practice are complete general and dimensional data for the high and low types of crown nuts recognized as SAE Standard. These nuts are primarily intended for application in automotive and other ground-based motor vehicles and industrial equipment to provide an ornamental or protective closure over end of bolts, studs, or screws.

This SAE Recommended Practice covers the mechanical and quality requirements for steel tapping screws used in automotive and related industries. It does not apply to corrosion resistant (stainless) steel screws. (Dimensional requirements for most types of screws mentioned herein are covered in ASME B 18.6.4, ‘Thread Forming and Thread Cutting Tapping Screws and Metallic Drive Screws’.)

This is a guide intended to aid the user in the proper selection and application of rivets as a fastening means. It consists of general information on the advantages of riveting, various methods of riveting, selection of rivets and design considerations.

Included herein are complete general and dimensional specifications for metric and inch types of spring nuts recognized as SAE standard. These nuts are intended for general use where the engagement of a single thread on the mating screw is considered adequate for the application. It should be noted that spring nuts having other configurations, dimensions, provisions for ground, etc., are available and manufacturers should be consulted.

Material-Cold drawn SAE 1112 or 1113 steel, alloy steel or copper alloy as specified by purchaser. Unless otherwise specified, steel pins shall have a flash plate of cadmium or zinc for protection of pins in transit or storage. Grooved Straight Pins must be free from burrs and all other defects that might affect their use and serviceability.

Table 3, Practical Length Increments and Ranges, indicates spring pin sizes. Information on availability of individual lengths in the various types, weights, and materials may be obtained from suppliers. The tolerance on length for coiled type spring pins shall be plus or minus 0.010 in. for sizes up to and including 5/16 in.; and plus or minus 0.015 in. for sizes larger than 5/16 in.

This SAE Standard covers the chemical, metallurgical, and mechanical requirements for two types of passenger car and truck wheel bolts, as follows: a Nonserrated shank bolts which are heat treated b Serrated shank bolts which are case hardened

This SAE Standard covers the mechanical and material requirements for eight property classes of steel, externally threaded metric fasteners in sizes M1.6 through M36, inclusive, and suitable for use in automotive and related applications.
