Overview
EN 3006:1994 (CEN) defines the characteristics of aerospace hexagon head bolts with a relieved shank and long thread, manufactured from the heat‑resisting steel FE‑PA92HT (A286). The standard classifies these fasteners with a mechanical strength of 900 MPa at ambient temperature and specifies suitability for elevated‑temperature service up to 650 °C. EN 3006 is intended for aerospace applications where high temperature resistance and reliable mechanical performance are required.
Key topics and requirements
The standard specifies the essential features and performance expectations without giving detailed drawings in this extract. Key technical topics include:
- Material designation: FE‑PA92HT (A286), a high‑temperature, corrosion‑resistant alloy for aerospace fasteners.
- Bolt geometry: hexagon head, relieved (reduced) shank under the head for controlled bearing and long thread length for adjustable engagement.
- Strength classification: 900 MPa class at ambient temperature and suitability for service temperatures up to 650 °C.
- Functional characteristics: mechanical integrity under thermal exposure, consistent thread engagement, and head form for torque application.
- Standard scope and identification: categorized under ICS 49.030.20 (bolts, screws, studs) and published as a CEN aerospace series standard.
Note: For dimension limits, tolerances, testing procedures and acceptance criteria consult the full EN 3006 document or related manufacturer datasheets and procurement specifications.
Applications
EN 3006 fasteners are used where combined high strength and high temperature capability are critical:
- Aircraft engine components and nacelles
- Hot‑section assemblies in turbines and auxiliary power units
- Structural joints exposed to elevated temperatures
- High‑temperature bolted connections in aerospace maintenance and overhaul
Keywords: EN 3006, A286, FE‑PA92HT, aerospace bolts, heat resisting steel, hexagon head bolts, high‑temperature fasteners, 900 MPa.
Who should use this standard
