EN 4695:2017 - Aerospace series - Tie Rod with integrated bolts - Assembly Code G, H and K

Overview

EN 4695:2017 - published by CEN and prepared by ASD‑STAN - defines the dimensions, tolerances and basic assembly details for aerospace tie rods with integrated bolts (Assembly Codes G, H and K). It applies to adjustable rod assemblies used in aircraft interior and sub‑structure applications over the temperature range −55 °C to 85 °C. The standard ensures interchangeability, consistent marking and predictable mass for rod assemblies where the rod ends must not be screwed completely apart.

Key topics and technical requirements

  • Assembly codes G, H, K - standardised configurations illustrated in figures; key parameters include d1 = 20.0 mm, SW = 22.2 mm and adjustable range for L1 = ±6.35 mm.
  • Dimensions & tolerances - metric dimensions (mm) and general tolerances per ISO 2768‑mK; length gradations in 6.35 mm steps.
  • Materials & surface treatments - typical materials: aluminium rod body (WL 3.1354, T4/T351) with anodizing and organic coatings (LN 9368 series), fork ends in stainless steel (WL 1.4548) and titanium inserts/bushes per EN 3311; passivation and approved coatings referenced.
  • Locking clips - specified by EN 4692: Type A (rotation restraint) and Type B (rotation restraint plus load transmission; no separate pin required). Clip B is available in RH/LH.
  • Mass calculation & marking - formula for total mass:
    mt = 0.3054 (g/mm) × h + 5 g + mr + ml, where h = L1 − L4r − L4l; mass tables and examples are provided. Marking follows EN 2424 (position: centre of rod body).
  • Technical specification & installation - detailed requirements cross‑referenced to EN 4691‑1 (technical specification), and locking/locking adhesives guidance (e.g., anaerobic/methacrylate examples cited).

Note: the standard identifies possible patent claims and lists patent numbers across multiple jurisdictions; users should be aware of potential IP/licensing considerations.

Applications and users

Who uses EN 4695:2017:

  • Aerospace design and structural engineers specifying adjustable tie rods for interior and sub‑structure assemblies.
  • Manufacturers and suppliers producing fork/eye ends, locking clips, inserts and full rod assemblies to ensure interchangeability.
  • Quality, procurement and certification teams verifying conformity, marking and mass budgets.
  • Maintenance and MRO organisations replacing or sourcing compliant tie rods.

Typical applications: adjustable tension/compression links in aircraft interiors, control linkages in sub‑structures where integrated bolt ends and standardised dimensions improve installation, inspection and spares management.
