1.1 This specification covers a group of common requirements that shall apply to carbon, alloy and stainless steel fasteners or fastener materials, or both, under any of the following ASTM Specifications (or under any other ASTM Specifications that invoke this specification or portions thereof):

Title of SpecificationsASTM Designation
Alloy-Steel and Stainless Steel Bolting Materials
for High-Temperature Service
A 193/A 193M
Carbon and Alloy Steel Nuts for Bolts for High
Pressure and High-Temperature Service
A 194/A 194M
Alloy Steel Bolting Materials for Low-Temperature
Service
A 320/A 320M
Alloy-Steel Turbine-Type Bolting Material
Specially Heat Treated for High-Temperature
Service
A 437/A 437M
High-Temperature Bolting Materials With Expansion
Coefficients Comparable to Austenitic Stainless
Steels
A 453/A 453M
Alloy-Steel Bolting Materials for Special Applications A 540/A 540M
Precipitation-Hardening Bolting Material (UNS
N07718) for High Temperature Service
A 1014/A 1014M

1.2 In case of conflict the requirements of the individual product specification shall prevail over those of this specification.

1.3 Additional requirements may be specified by mutual agreement between the purchaser and supplier.

1.4 Supplementary requirements are provided for use at the option of the purchaser. The supplementary requirements only apply when specified individually by the purchaser in the purchase order or contract.

1.5 This specification is expressed in both inch-pound units and in SI units; however, unless the purchase order or contract specifies the applicable M specification designation (SI units) the inch-pound units shall apply. The values stated in either inch-pound or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.


This specification covers a group of common requirements that shall apply to carbon, alloy, and stainless steel fasteners or fastener materials, or both. These materials are intended for use at any temperature from cryogenic to the creep range. Requirements for the melting process and quality control procedures for ingot cast and strand cast products are detailed. Bars and fasteners shall be produced in accordance with the product specification. The chemical composition, as to heat and product analyses, shall conform to the limits of the product specification. Bars, fasteners, bolting materials, and specimen machined from fasteners shall meet the mechanical requirements which shall be determined by the following tests: (1) proof load test by mandrel/tension or compression methods, (2) cone proof load test, (3) impact test, and (4) hardness test. Assembly for the proof load and cone proof tests are illustrated. The depth of decarburization shall be determined by metallographic etching and if needed, microhardness testing.
