Overview

EN ISO 898-1:2009/prA1 (ISO 898-1:2009/DAM 1:2010) is a draft amendment to the international standard that defines the mechanical properties of fasteners made of carbon and alloy steels. It applies to bolts, screws and studs with specified property classes for both coarse thread and fine pitch thread. The amendment updates test and manufacturing requirements and clarifies normative text to ensure consistent strength, hardness and performance of threaded fasteners.

Note: this document was prepared by ISO/TC 2 (Fasteners) in collaboration with CEN/TC 185 and circulated as a draft amendment for parallel enquiry.

Key topics and requirements

• Scope: mechanical properties and verification procedures for carbon- and alloy-steel fasteners (bolts, screws, studs) with specified property classes; applies to coarse and fine threads.
• Property classes and mechanical performance: establishes requirements and verification for tensile strength, proof load and hardness (as per clauses in the standard).
• Testing and hardness: amendment specifies that hardness determination shall be performed in accordance with clause 9.9.4.2 and tightens language from "should" to "shall" in selected requirements to increase enforceability (e.g., clause 9.3.4).
• Heat treatment and surface preparation: footnote change in Table 2 (clause 6) requires dephosphating prior to heat treatment, clarifying sequence for surface prep and thermal processing.
• Manufacturing and tooling controls: clause updates prohibit use of certain self-aligning tooling features that affect wedge angle (clause 9.1.3) and add specific stud acceptance criteria (clause 9.3.2) - e.g., a tap end that resists higher ultimate tensile load than the nut end.
• Editorial and technical clarifications: several small but important textual changes (clause 3.8 and clause 9.11.3.3) improve precision of requirements.

Applications

• Quality control and inspection of fasteners in manufacturing and supply chains.
• Design and specification of bolted joints in mechanical, automotive, construction and industrial equipment.
• Procurement and supplier qualification: use for contract specifications to ensure consistent mechanical properties.
• Test laboratories: reference for test methods, hardness checks and acceptance criteria.

Who uses this standard

• Fastener manufacturers and heat-treatment shops
• OEMs and component designers
• QA/QC engineers and material testing laboratories
• Procurement specialists and standards compliance officers

Related standards

• ISO 898 series (other parts addressing additional fastener types and tests)
• National/adopted CEN versions (EN ISO 898-1) for European regulatory and procurement alignment

This draft amendment is submitted to CEN members for parallel enquiry. It has been drawn up by the Technical Committee CEN/TC 185.

This draft amendment A1, if approved, will modify the European Standard EN ISO 898-1:2009. If this draft becomes an amendment, CEN
members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for inclusion of this amendment
into the relevant national standard without any alteration.

This draft amendment was established by CEN in three official versions (English, French, German). A version in any other language made
by translation under the responsibility of a CEN member into its own language and notified to the CEN Management Centre has the same
status as the official versions.
