EN 2928:1996 - Aerospace series - Bolts, double hexagon head, relieved shank, long thread, in heat resisting nickel base alloy NI-P100HT (Inconel 718), silver plated - Classification: 1 275 MPa (at ambient temperature)/650 °C

Overview

SIST EN 2928:2001 is a European standard specifying the requirements for aerospace-grade bolts featuring double hexagon heads, relieved shanks, and long threads. These bolts are manufactured from the heat-resistant nickel base alloy NI-P100HT, commonly known as Inconel 718, and are silver plated to enhance corrosion resistance. Designed for high-performance aerospace applications, the standard classifies these bolts for use at an ambient temperature tensile strength of 1,275 MPa and service temperatures up to 650 °C. This makes them ideal for critical components requiring both mechanical strength and thermal stability.

Key Features

  • Bolt Type: Double hexagon head with relieved shank and extended threading
  • Material: Nickel base alloy NI-P100HT (Inconel 718), known for exceptional heat resistance and mechanical properties
  • Surface Finish: Silver plating for enhanced corrosion protection and conductivity
  • Mechanical Classification: 1,275 MPa tensile strength at room temperature
  • Temperature Rating: Certified for use up to 650 °C without degradation
  • Standardization: Developed and maintained by CEN to ensure uniformity in aerospace fasteners

Practical Applications

SIST EN 2928:2001 bolts are essential in aerospace engineering where components must withstand extreme conditions such as high temperatures and mechanical stresses. Typical uses include:

  • Aircraft structural assemblies: Securing critical load-bearing joints where strength and heat resistance are paramount
  • Engine components: Fastening parts exposed to elevated temperatures within jet engines and turbine assemblies
  • High-performance aerospace equipment: Reliable fastening solutions in supersonic and space applications requiring durability under thermal cycling
  • Maintenance and repair operations: Standardized bolts enabling consistent replacement parts that meet strict safety and performance criteria

The material choice and design features ensure that these bolts maintain stability and prevent failure in harsh operational environments, directly contributing to overall aircraft safety and efficiency.

Related Standards

To complement SIST EN 2928:2001 in aerospace fastener selection and quality assurance, the following standards may be referred to:

  • EN 9100: Quality management systems for aerospace manufacturing
  • EN ISO 898-1: Mechanical properties of fasteners made of carbon steel and alloy steel
  • EN 473: Non-destructive testing certification for personnel
  • ASTM F468: Standard specification for stainless steel bolts used in aerospace applications

Together, these standards help ensure the quality, reliability, and traceability of aerospace fasteners, including those covered by SIST EN 2928:2001.
