1.1 This specification covers the chemical and mechanical requirements of quenched and tempered alloy steel bolts, studs, and other externally threaded fasteners 4 in. and under in diameter for application at normal atmospheric temperatures, where high strength is required and for limited application at elevated temperature (Note 1). Any alloy steel capable of meeting the minimum mechanical and chemical properties set forth in this specification may be used.
Note 1—For bolts, studs, or other externally threaded fasteners, to be used at elevated temperatures, refer to Specification A 193
1.2 Two levels of bolting strength are covered, designated Grades BC and BD. Selection will depend upon design and the stresses and service for which the product is to be used.
Note 2—Quenched and tempered alloy steel bolts for structural steel joints up through 1½ in. in diameter are covered in Specification A 490 When bolts of Grade BD of this specification are considered for pretentioned applications in excess of 50 % of the bolt tensile strength, the additional requirements of head size, maximum tensile strength, nut size and strength, washer hardness, tests, and inspections contained in Specification A 490
1.3 Nuts are covered in Specification A 563 A Nuts of other grades and styles having specified proof load stresses (Specification A 563
Grade of Fastener and Surface Finish
Nut Grade and
StyleA
BC, plain (or with a coating of insufficient thick-
ness to require over-tapped nuts)
C, heavy hex
BC, zinc-coated (or with a coating thickness re-
quiring over-tapped nuts)
DH, heavy hex
BD, all finishes
DH, heavy hex
1.4 The values stated in inch-pound units are to be regarded as the standard.
1.5 Terms used in this specification are defined in Terminology F 1789
