SAE has released a new 2013 edition of SAE J429, “Mechanical and Material Requirements for Externally Threaded Fasteners,” and you can purchase it now from Document Center Inc. in both paper and pdf format. The Ground Vehicle Standard covers the mechanical and material requirements for inch-series steel bolts, screws, studs, screws for sems (screw and washer assemblies), and U-bolts in sizes to 1-1/2 in. inclusive.
FYI: The U-bolts in SAE J429 2013 are used predominantly in the suspension and related areas of vehicles. They are treated like studs in this document. SAE recommends that designers using this standard review the actual load-carrying capacity of them with saddle load tests.
The studs in this standard are cylindrical rods of moderate length, threaded on either one or both ends, or even throughout the entire length of the stud. Any products that use a head, collar, or something similar are referred to as bolts. Table 2 covers the chemical composition requirements.
The 2013 Edition is a revision of the previous J429 released in September of 2009. The new edition replaces all previous editions, which are now obsolete.
