Overview

SIST EN ISO 14583:2012 is an international standard specifying the characteristics of hexalobular socket pan head screws, also known as Torx pan head screws. Developed by the International Organization for Standardization (ISO) and adopted by the European Committee for Standardization (CEN), this standard covers product grade A screws with thread sizes ranging from M2 up to M10. It provides detailed dimensions, mechanical properties, tolerances, and requirements to ensure consistency, quality, and interoperability for manufacturing and engineering applications. The 2011 edition supersedes the previous 2001 version and incorporates minor revisions to enhance clarity and applicability.

Key Topics

  • Scope and Application: SIST EN ISO 14583:2012 applies specifically to hexalobular socket pan head screws of grade A, with thread sizes from M2 to M10. It defines key attributes such as thread pitch, head dimensions, socket size, and material specifications.
  • Dimensions and Tolerances: The standard provides exact measurements for pan head height, socket dimensions, thread pitch, and screw length. Dimensions are detailed in millimetres with tolerance classes following ISO 4759‑1. The document includes nominal and maximum/minimum values to guide manufacturers.
  • Materials and Mechanical Properties: Steel, stainless steel, and non-ferrous metals are covered with references to established ISO standards for mechanical properties such as ISO 898-1 (carbon and alloy steel), ISO 3506-1 (stainless steel), and ISO 8839 (non-ferrous metals). Property classes such as 4.8 and A2-70 are used for specification.
  • Surface Coatings and Finishes: Requirements for electroplating coatings, zinc flake coatings, and other finishes are referenced to ISO 4042 and ISO 10683 to ensure corrosion resistance and surface integrity.
  • Hexalobular Socket Design: The internal six-lobed driving feature is standardized per ISO 10664 to optimize torque transmission and reduce cam-out.
  • Acceptance and Inspection: Surface discontinuities and product inspections follow ISO 6157-1 and ISO 3269 to guarantee product quality and conformity.
  • Designation Format: Example screw designation:
    Hexalobular socket pan head screw ISO 14583 - M5 × 20 - 4.8
    This details thread size, nominal length, and property class clearly for ordering and classification.

Applications

Hexalobular socket pan head screws standardized under SIST EN ISO 14583:2012 are widely used in various industries due to their reliable torque transmission and compact head design. Common applications include:

  • Automotive assembly where precision fastening and resistance to loosening are critical.
  • Electronics manufacturing, leveraging the small size and high torque capabilities for securing components.
  • Aerospace and defense sectors requiring high-strength fasteners with consistent quality.
  • Mechanical engineering and machinery construction, offering durable, corrosion-resistant fastening solutions.
  • General industrial maintenance and repair, benefiting from the standardized sizing and availability.

Their design facilitates efficient assembly with hexalobular drivers or bits, improving productivity and reducing tool wear. The standard ensures compatibility across suppliers and end-users internationally.

Related Standards

SIST EN ISO 14583:2012 references and works in conjunction with several key ISO standards to provide a comprehensive framework for fasteners:

  • ISO 261 and ISO 965-2: General-purpose metric screw thread dimensions and tolerances
  • ISO 898-1 and ISO 3506-1: Mechanical properties of steel and stainless steel fasteners
  • ISO 10664: Specification of hexalobular (Torx) internal driving features
  • ISO 4042: Electroplated coatings on fasteners
  • ISO 10683: Non-electrolytically applied zinc flake coatings
  • ISO 4759-1: Tolerances for fasteners by product grade
  • ISO 6157-1: Surface discontinuity requirements
  • ISO 3269: Acceptance inspection procedures

These interconnected standards support engineers, manufacturers, and quality inspectors in delivering consistent, reliable fastener solutions compliant with international best practices.
