Overview

EN 2236:1992 is a CEN aerospace series standard that sets out the technical specifications for headed, close-tolerance shear pins made from alloy steel. The standard applies when it is referenced on a product standard or on a definition document. It has been adopted as a national variant (for example, SIST EN 2236:2001) by member bodies.

This standard is intended for designers, manufacturers and quality engineers who need a consistent reference for the procurement and verification of close-tolerance headed pins used in aerospace assemblies.

Key Topics

The standard defines the technical requirements relevant to headed, close-tolerance alloy-steel pins. Core elements covered include:

• Scope and applicability - when the standard should be invoked (product standard or definition document reference).
• Product definition - identification of pins by configuration: headed, close-tolerance shank, alloy steel construction.
• Manufacturing and quality controls - requirements to ensure consistent production and interchangeability.
• Inspection and verification - criteria that support acceptance and traceability.

Note: EN 2236:1992 provides the framework and requirements; specific values and procedures are defined within the standard text or in referencing product documents.

Applications

This standard is specifically tailored for aerospace uses where precision pins are required for reliable assembly and controlled shear behavior. Typical applications include:

• Component locating and alignment where close-tolerance shanks ensure accurate fit.
• Shear-pin applications that require a headed pin form for retention and removal.
• Production and supply chains that require standardization to ensure interchangeability between suppliers and OEMs.

Benefits of applying EN 2236:1992:

• Improved consistency in manufacturing and inspection of headed pins.
• Clear criteria for procurement and acceptance when cited by product standards.
• Reduced risk of fit or functional failure due to uncontrolled tolerances.

Related Standards

• Product standards or definition documents that reference EN 2236:1992 for pin specifications.
• National adoptions or translations (for example, SIST EN 2236:2001) that implement the CEN text at country level.
• Other aerospace material and fastener standards referenced by product specifications - consult the relevant product standard for cross-references.

For procurement, design, and quality assurance teams, citing EN 2236:1992 in product documentation ensures a harmonized approach to material selection, dimensional control and acceptance criteria for headed, close-tolerance alloy-steel pins used in aerospace assemblies.
