ASTM A 354 REV A Document Information:
Title
Standard Specification for Quenched and Tempered Alloy Steel Bolts, Studs, and Other Externally Threaded Fasteners
ASTM International
Publication Date:
Dec 1, 2007
Scope:
This specification2 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/A
193M.
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. Alloy steel bolts, studs, and other externally
threaded fasteners (that is, heavy hex-structural bolts over 1½
in., hex bolts, anchor bolts, and countersunk bolts) exhibiting
similar mechanical properties to bolts conforming to Specification
A 490 shall be covered by Grade BD of this specification.
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 should be carefully
considered.
Nuts are covered in Specification A 563.
The values stated in inch-pound units are to be regarded as the
standard.
Terms used in this specification are defined in Terminology F
1789 unless otherwise defined herein.
*A Summary of Changes section appears at the end of this
standard.
2 For ASME Boiler and Pressure Vessel Code
applications see related Specification SA-354 in Section II of that
Code.
