Overview
EN 4134:2009 is a CEN (ASD‑STAN) aerospace standard that specifies the characteristics, designation and marking of bolts with a normal hexagonal head, coarse tolerance normal shank and long thread, manufactured from heat‑resisting nickel‑base alloy and aluminium IVD coated. The standard covers bolts classified for a minimum tensile strength of 1 250 MPa at ambient temperature and rated for service temperatures up to 425 °C (maximum temperature after which original characteristics must be retained on return to ambient).
Keywords: EN 4134:2009, aerospace bolts, heat resisting nickel base alloy, aluminium IVD coated, MJ threads, hexagonal head bolts, 1250 MPa, 425 °C.
Key topics
- Materials and strength
- Heat‑resisting nickel‑base alloys referenced via EN 2952, EN 3219 or TR 3775 (classification 1 250 MPa).
- Dimensions and thread forms
- MJ thread series per ISO 5855‑2 and rolled external threads per ISO 3353‑1; diameter codes cover MJ3×0.5 to MJ20×1.5 with corresponding length codes.
- Dimensions and tolerances specified in millimetres and apply after surface treatment.
- Surface treatment
- Aluminium IVD coating per MIL‑DTL‑83488D (Type II, Class 3) with deposit thickness 7–20 µm, followed by mechanical blasting and chromate conversion coating within 24 h. Optional lubrication (cethylic alcohol, code E).
- Note: maximum service temperature is linked to the chosen surface treatment.
- Quality, testing and approval
- Manufacturer approval and quality systems per EN 9100; part qualification per EN 9133.
- Tolerances of form and position per ISO 7913.
- Test loads use a coefficient of 0.81 as modified by the standard.
- Designation and marking
- Standard provides a designation format (example: EN4134H050040E) and marking rules referenced to EN 2424.
Applications
- Designed for critical aerospace fastener applications requiring high tensile strength and high‑temperature resistance: engine and hot‑section assemblies, exhaust structures, high‑temperature attachment points and structural components exposed to elevated temperatures.
- Typical users: aerospace fastener manufacturers, OEM design and procurement engineers, maintenance/repair organizations, quality managers and specification writers.
