SAE J1199-2013 SAE J 1199-2013 标准

适用范围: 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. Products included are bolts@ screws@ studs@ U-bolts@ preassembled screw and washer assemblies (sems)@ and products manufactured the same as sems except without washer. Products not covered are tapping screws@ thread-rolling screws@ and self-drilling screws@ Mechanical and material requirements for these products are covered in other SAE documents. The term stud as referred to herein@ applies to a cylindrical rod of moderate length@ threaded on either one or both ends or through its entire length. It does not apply to headed@ collard@ or similar products which are more closely characterized by requirements shown herein for bolts. For specification purpose@ this document treats U-bolts as studs. Thus@ wherever the word studs appear@ U-bolts is also implied. U-bolts covered by this documents are those used primarily in the suspension and related areas of vehicles@ (Designers should recognize that the U configuration may not sustain a load equivalent to two bolts ro studs of the same size and grade@ thus actual load-carrying capacity of U-bolts should be determined by saddle load tests.)
