ASTM A962/A962M is the ASTM standard specification for common requirements for bolting intended for use at any temperature from cryogenic to the creep range. It provides a shared technical basis for bolting products that may be used across very different service conditions, helping define consistent expectations for materials, manufacture, and conformity. For buyers, engineers, and quality teams, this standard matters because it supports clearer procurement and more reliable evaluation of bolting intended for demanding temperature environments.

Purpose of ASTM A962/A962M

The purpose of ASTM A962/A962M is to establish common requirements that apply to bolting covered for use over a wide temperature range, including very low temperatures and conditions approaching the creep range. As a common-requirements document, it helps create consistency across related bolting products by setting a baseline for technical and quality expectations. This makes it useful when comparing materials, reviewing compliance, or coordinating specifications for bolted assemblies where temperature exposure is an important design consideration.

Common use cases of ASTM A962/A962M

ASTM A962/A962M is commonly used when specifying bolting for applications where service temperature can influence performance and acceptance requirements. It is relevant to fasteners selected for equipment, assemblies, and systems that may experience cryogenic conditions or elevated temperatures where creep becomes a concern. The standard is often used in procurement, inspection, and product documentation to help align bolting requirements across related ASTM specifications and support more consistent manufacturing and testing workflows.

Why ASTM A962/A962M matters

This standard matters because bolting performance can change significantly with temperature, and a common-requirements specification helps reduce ambiguity in material selection and compliance review. ASTM A962/A962M supports more consistent quality control by giving stakeholders a shared reference for what to check before release, acceptance, or installation. That can improve procurement clarity, reduce risk in critical bolted joints, and make it easier to evaluate whether the bolting meets the intended service conditions.
