Overview

EN 6101:2022 - "Aerospace series - Rivet, 100° medium flush head, close tolerance - Inch series" (CEN) specifies the configuration, dimensions, tolerances and mass for inch-series solid rivets with a 100° medium flush head and close tolerance intended for aerospace applications. This European Standard supersedes EN 6101:2016 and includes provisions for standard and oversize (repair) rivets, material options, surface treatments and product marking.

Key topics and requirements

• Configuration and dimensions: Defines rivet head and shank geometry (see Figure 1) and tabulates precise dimensions, tolerances and masses (Tables 1–3). Dimensions are expressed in millimetres though the parts are inch-series.
• Oversize rivets: Specifies allowable tolerances and dimensions for oversize rivets intended for repair use (Table 2).
• Materials and finishes: Lists approved materials and surface treatments (Table 4) including aluminium alloys (e.g., 1050A-H14, 2117-T42, 2017A-T42, AL-P5056A, 7050-T73), titanium (44.5 Cb) and heat-resisting nickel alloy NI‑PD9001 (NiCu31). Includes guidance on anodizing, chromating, cadmium plating and other finishes.
• Mechanical limits: Provides technical specification references for alloy classes; for example, NiCu31 rivets have a specified shear strength range (340–407 MPa).
• Marking and identification: Requires material symbols and manufacturer identification on rivet heads (manufacturer ID mandatory for diameter code 4 and larger). Oversize rivets are identified by a triangular mark on the shank end.
• Designation and supply: Standardizes part numbering/length codes and mass per 1 000 parts for procurement consistency.
• Quality and qualification: Manufacturer must operate an approved aerospace production organization and maintain a quality management system (e.g., EN 9100). Qualification testing should follow aerospace procedures (e.g., EN 9133) unless otherwise agreed.

Applications and users

EN 6101:2022 is essential for:

• Aerospace design and structural engineers specifying fasteners for aircraft assemblies
• Fastener manufacturers producing inch‑series close‑tolerance flush-head rivets
• Procurement teams and supply chain managers ensuring standard-compliant parts
• Maintenance, repair and overhaul (MRO) organizations using oversize rivets for repairs
• Quality and regulatory teams verifying marking, traceability and QMS conformance

Keywords: EN 6101:2022, aerospace rivet, 100° medium flush head, close tolerance rivets, inch series, rivet dimensions, rivet tolerances, rivet materials, NiCu31.
