Overview
EN 28839:1991 (ISO 8839:1986) specifies the mechanical properties for metric fasteners - bolts, screws, studs and nuts - made of non‑ferrous metals (copper and copper alloys, aluminium and aluminium alloys). The standard covers products with nominal thread diameters from M1.6 to M39 and uses metric ISO threads in accordance with ISO 261. It does not apply to fasteners with special property requirements.
Key topics and requirements
- Scope and applicability: Fasteners (bolts, screws, studs, nuts) of non‑ferrous metals, nominal diameters M1.6–M39, metric threads per ISO 261.
- Material coverage: Copper, copper alloys, aluminium and aluminium alloys (non‑ferrous fasteners).
- Mechanical properties: Defines the mechanical characteristics required for these fasteners (the standard sets the performance criteria manufacturers and purchasers should rely on).
- Exclusions: Explicitly excludes products with special property requirements (e.g., proprietary heat treatments, coatings or other specialised properties not covered by the standard).
- Harmonization: Identical to ISO 8839:1986 and adopted by CEN; national adoptions (e.g., SIST EN 28839) reflect the same content.
- Classification and codes: Listed under ICS categories for bolts, screws, studs and nuts (21.060.10 / 21.060.20).
Practical applications
- Fastener selection and specification for components where non‑ferrous metals are required due to corrosion resistance, electrical conductivity or weight reduction (electronics, marine fittings, electrical assemblies, lightweight structures).
- Procurement and contract documents: Ensures suppliers deliver bolts, screws, studs and nuts that meet agreed mechanical performance standards.
- Quality control and inspection: Provides the reference for verifying mechanical behaviour of non‑ferrous fasteners during incoming inspection and production testing.
- Design guidance: Helps engineers choose appropriate thread sizes and material families when designing assemblies that use non‑ferrous fasteners.
Who should use this standard
- Fastener manufacturers and material suppliers producing non‑ferrous bolts, screws, studs and nuts.
- Design and mechanical engineers specifying fasteners in product designs.
- Procurement and quality assurance teams verifying supplier conformity.
- Test laboratories and compliance bodies assessing mechanical performance of non‑ferrous fasteners.
Related standards
- ISO 8839:1986 - identical international reference.
- ISO 261 - metric ISO thread specifications referenced for thread form and sizes.
