Overview
EN 6081:2022 - Aerospace series - Rivet, universal head, close tolerance - Inch series - is a CEN (ASD‑STAN) standard that specifies the configuration, dimensions, tolerances and mass for universal‑head, close‑tolerance rivets in the inch series for aerospace applications. Although called an inch series, dimensions and tolerances are expressed in millimetres and the standard provides detailed tables and figures for selection, including oversize rivet options and mass conversion factors.
Key topics and technical requirements
- Scope and configuration: Defines the universal head geometry and shank features (see Figure 1) and permissible shank diameter increases near the head.
- Dimensions, tolerances and masses: Detailed Tables list nominal diameters, head and shank dimensions, length codes and mass per 1 000 parts. Oversize rivets and length increment rules (1/16 in steps and optional 1/32 in increments) are covered.
- Materials and surface treatments: Specifies allowable materials and finishes, including aluminium alloys (e.g., 1050A‑H14, 2117‑T42, 2017A‑T42, 5056A‑H32, 7050‑T73) and titanium alloy 44.5 Cb. Surface treatments reference MIL and ISO processes (e.g., MIL‑A‑8625 anodizing, MIL‑DTL‑5541 chromate, ISO 8080 for titanium).
- Designation and marking: Head marking conventions identify material and manufacturer (manufacturer ID required for diameter code 4 and larger). Oversize rivets are identified by an indented triangular mark on the shank end.
- Technical specifications: Aluminium rivets reference prEN 6104; titanium rivets reference NASM 5674 (with specific finish exceptions).
- Quality management: Manufacturers must be approved aerospace production organizations and maintain an aerospace quality system (e.g., EN 9100 or equivalent). Qualification per EN 9133 (or equivalent) is required unless otherwise agreed.
Applications and users
EN 6081 is intended for use where high‑precision, close‑tolerance universal‑head rivets are required in aerospace structures and assemblies. Typical users:
- Aerospace OEMs and Tier‑1 suppliers specifying fasteners for airframe assemblies
- Fastener manufacturers producing rivets to aerospace standards
- MRO organizations and procurement teams verifying part conformity
- Design and stress engineers selecting fasteners for structural joints, skin-to-frame attachments, and fittings
Practical benefits include consistent interchangeability, traceable material/finish identification, and clear production/inspection criteria to support structural integrity and regulatory compliance.
