Overview

EN 2936:1996 (adopted as SIST EN 2936:2001) is an aerospace-series standard that specifies the characteristics of T-head bolts with relieved shank and long thread, manufactured from the heat‑resisting nickel‑base alloy NI‑P101HT (Waspaloy) and silver plated. The fasteners are classified for mechanical performance 1 210 MPa (at ambient temperature) and rated for use up to 730 °C. This standard is part of the CEN aerospace series and is indexed under ICS 49.030.20 (bolts, screws, studs).

Key topics and requirements

• Material specification: Fasteners made from NI‑P101HT (Waspaloy) - a high‑temperature nickel‑base alloy suitable for hot aerospace environments.
• Bolt geometry: T‑head configuration with relieved (reduced) shank and long thread; intended to meet specific assembly and clamping needs.
• Surface finish: Silver plating for corrosion protection, electrical conductivity where required, and specific surface properties.
• Mechanical classification: 1 210 MPa strength class at ambient temperature and suitability for service up to 730 °C, indicating high-temperature mechanical performance.
• Conformance and marking: Provisions for identifying material, classification, and finish to support traceability (as typical for aerospace fastener standards).
• Scope limitation: Focused on the defined bolt type and material; it does not replace general installation, torqueing, or assembly standards.

Applications

• Aerospace structures and assemblies exposed to high temperatures (hot sections of engines, auxiliary equipment, or airframe areas with elevated thermal stress).
• Situations requiring a T‑head bolt for captive or slot‑mounted fastening where a relieved shank and long thread are necessary for adjustment or clearance.
• Use by aerospace fastener manufacturers, OEM procurement teams, design engineers, maintenance and repair organizations, and quality assurance bodies specifying high‑temperature fasteners.

Who uses this standard

• Design engineers specifying components for high‑temperature aerospace systems.
• Manufacturers producing NI‑P101HT (Waspaloy) T‑head bolts to ensure dimensional and material conformity.
• Procurement and quality teams verifying batch traceability, markings, and plating.
• Maintenance/overhaul facilities selecting appropriate replacement fasteners for certified assemblies.

Related standards

• This document is part of the CEN aerospace series and is nationally adopted as SIST EN 2936:2001. For broader fastener selection, refer to other aerospace-series standards governing bolt dimensions, torqueing, testing, and installation practices.
