Description / Abstract:
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.)
