Overview

EN 3297:1998 - Aerospace series - Inserts, thin wall, self-locking, MJ threads, in heat resisting nickel base alloy NI‑P100HT (Inconel 718) - Technical specification. Published by CEN, this standard defines the required characteristics, qualification and acceptance requirements for thin‑walled, self‑locking threaded inserts with MJ threads manufactured from NI‑P100HT. It applies in all cases where EN 3297 is referenced in design, procurement or certification documentation.

Key topics

• Scope and applicability: establishes that the specification covers thin‑wall self‑locking inserts with MJ threads made from the heat‑resisting nickel base alloy NI‑P100HT (Inconel 718).
• Material specification: identifies the use of NI‑P100HT (Inconel 718) as the alloy for these inserts and implies material suitability for elevated‑temperature aerospace applications.
• Product characteristics: covers the defining attributes of the inserts such as geometry, thread form (MJ threads) and self‑locking features required for reliable joint performance.
• Qualification and acceptance requirements: sets out the need for manufacturer qualification and acceptance criteria to ensure consistency, safety and interchangeability when the standard is invoked.
• Documentation and traceability: requires appropriate records, marking and documentation to demonstrate compliance with the standard when referenced by designers, purchasers or regulatory bodies.

Applications

• Aerospace structures and engines: used where high‑temperature resistance and secure threaded joints are required - for example in components exposed to elevated temperatures and corrosive environments.
• Repair and retrofit: provides a basis for selecting inserts for maintenance activities where original‑equipment specifications reference EN 3297.
• High‑performance fastener systems: applicable wherever thin wall, self‑locking inserts with MJ threads are preferred due to space, weight or locking requirements.

Who uses this standard

• Aerospace designers and structural engineers specifying threaded inserts for parts and assemblies
• Fastener and insert manufacturers producing NI‑P100HT (Inconel 718) inserts
• Quality, procurement and certification teams verifying compliance with referenced specifications
• Maintenance, repair and overhaul (MRO) organizations replacing or installing inserts in service items

Related standards

• Other CEN/EN and aerospace series standards governing threaded inserts, fasteners and thread forms (referenced in procurement or design documents).
• International thread and fastener standards commonly used alongside EN specifications.
