Overview
EN ISO 4029:2026 specifies the characteristics and requirements for hexagon socket set screws with cup point, covering metric coarse pitch threads from M1,6 to M30 for steel and M1,6 to M24 for stainless steel. The standard applies to product grade A fasteners and provides detailed guidance on dimensions, mechanical properties, surface finishes, and designation. Set screws covered by this standard are intended primarily for applications not subject to tensile loads. Prepared by CEN and ISO, EN ISO 4029:2026 aligns international requirements for consistency in fastener quality across manufacturing and engineering sectors.
Key Topics
Design and Dimension: This standard sets out the required dimensions for hexagon socket set screws with cup point, including thread sizes, lengths, and tolerances. It references ISO 225 and ISO 724 for symbols and thread dimensions, ensuring compatibility and interchangeability in assembly.
Materials: The document covers set screws made of steel (M1,6 to M30) and stainless steel (M1,6 to M24). For additional requirements, hardness classes can be chosen from ISO 898-5 (steel) or ISO 3506-3 (stainless steel).
Mechanical Properties: Only suitable for applications where the fastener is not subjected to tensile loads. The mechanical properties, such as hardness and grade, are specified for both steel and stainless steel to guarantee performance according to international standards.
Surface Finishes: Details acceptable finishes, including as processed, clean and bright, passivated, and various coatings per ISO 4042 and ISO 10683. Any non-standard finishes must be agreed upon between supplier and purchaser.
Product Identification: Defines the required labelling on packaging to ensure traceability, specifying details such as reference to ISO 4029, thread size, length, material grade, surface finish, manufacturer, lot number, and quantity.
Applications
EN ISO 4029:2026 finds wide application in mechanical engineering, machinery construction, automotive assembly, electronics, and equipment manufacturing. Key practical benefits include:
- Secure Adjustment and Clamping: Hexagon socket set screws with a cup point are commonly used to secure or adjust parts in precision assemblies, such as shafts, collars, and couplings, offering a secure hold without the need for through-holes or nuts.
- Equipment Maintenance: Standardized set screws are crucial for repair and maintenance activities, ensuring the availability of compatible replacements across global supply chains.
- International Projects: By adhering to EN ISO 4029:2026, manufacturers and engineering firms facilitate cross-border projects, supporting quality assurance and minimizing incompatibility risks.
This standard ensures that users across industries can specify, source, and implement reliable socket set screws, enhancing process efficiency, safety, and product longevity.
Related Standards
EN ISO 4029:2026 references and is complemented by several related international standards, which may be consulted for further requirements on fasteners:
- ISO 898-5: Mechanical properties of steel set screws
- ISO 3506-3: Mechanical properties of stainless steel set screws
- ISO 888: Nominal and thread lengths
- ISO 965-1: Thread tolerances
- ISO 4042: Electroplated coating systems
- ISO 10683: Non-electrolytically applied zinc flake coatings
- ISO 4753: Fastener end styles
- ISO 8991: Designation system for fasteners
- ISO 1891-4: Labelling requirements for fasteners
By referencing these standards, EN ISO 4029:2026 ensures comprehensive and harmonized requirements, supporting quality management and supply chain transparency in the fastener industry.
