SIST EN 2364:2001

Aerospace series - Pins, shear, headed, close tolerance

This standard specifies the characteristics of close tolerance headed shear pins in steel: cadmium plated, for use in aerospace at temperatures below 235 °C.
These shear pins are intended for use as a connecting part in conjunction with collars EN 2365 and split pins EN 2367.

Overview

EN 2364:1989 specifies the characteristics of close-tolerance headed shear pins made of steel and cadmium plated for aerospace applications. These components are intended for use at temperatures below 235 °C and serve as connecting parts in assemblies that use EN 2365 collars and EN 2367 split pins. The standard belongs to the CEN aerospace series and focuses on ensuring dimensional quality, fit, and material treatment consistent with aerospace requirements.

Key Topics

• Product scope: Close-tolerance, headed shear pins manufactured from steel with cadmium plating for corrosion resistance.
• Temperature rating: Intended for service at temperatures below 235 °C.
• Function: Designed as connecting or shear elements that provide controlled failure or secure retention in conjunction with mating collars and split pins.
• Compatibility: Specified to be used with EN 2365 collars and EN 2367 split pins for reliable joint assemblies.
• Materials and plating: Steel substrate with cadmium plating to improve corrosion protection in aerospace environments.

Applications

EN 2364:1989 shear pins are used where a compact, precise locating and shear function is required in aircraft and aerospace structures and mechanisms. Typical practical uses include:

• Assembly retention where a shear feature protects primary structure by providing a predictable failure mode under overload.
• Secure, close-tolerance alignment of mating parts when combined with EN 2365 collars.
• Temporary or semi-permanent connections that can be disassembled or replaced using EN 2367 split pins.

Benefits for engineers and procurement teams:

• Predictable behavior: The shear design helps manage overloads without damaging adjacent components.
• Precision fit: Close tolerance manufacture improves repeatable assembly and alignment.
• Corrosion resistance: Cadmium plating offers improved protection in many aerospace environments (subject to applicable environmental and handling restrictions).

Related Standards

• EN 2365 - Collars intended to be used with the shear pins specified in EN 2364.
• EN 2367 - Split pins designed for joint retention in assemblies that include EN 2364 shear pins.
• CEN aerospace series - EN 2364 forms part of the broader family of aerospace fastener and component standards.

When selecting or specifying components per EN 2364:1989, verify compatibility with mating parts (EN 2365, EN 2367), confirm the operating temperature does not exceed 235 °C, and consider corrosion-control practices and environmental regulations related to cadmium plating. For procurement or design decisions, refer to the full standard text for exact dimensional and acceptance criteria.
