BS EN 4012:2025 Aerospace Series Nut
Introducing the BS EN 4012:2025 Aerospace Series Nut, a pinnacle of engineering excellence designed to meet the rigorous demands of the aerospace industry. This standard sets the benchmark for high-performance nuts, ensuring reliability and safety in critical applications.
Product Overview
The BS EN 4012:2025 standard specifies the requirements for a bihexagonal, self-locking nut made from a heat-resisting nickel base alloy, specifically NI-PH2601 (Inconel 718). This material is renowned for its exceptional strength and resistance to extreme temperatures, making it an ideal choice for aerospace applications.
Key Features
- Material: Nickel base alloy NI-PH2601 (Inconel 718)
- Coating: MoS2 (Molybdenum Disulfide) for enhanced lubrication and reduced friction
- Classification: 1 550 MPa at ambient temperature / 425 °C
- Design: Bihexagonal, self-locking for secure fastening
Why Choose Inconel 718?
Inconel 718 is a high-strength, corrosion-resistant nickel chromium material used at temperatures ranging from cryogenic to 704°C. Its outstanding tensile, fatigue, creep, and rupture strength make it a preferred choice for demanding environments. The addition of MoS2 coating further enhances its performance by providing excellent lubrication, reducing wear and extending the lifespan of the nut.
