Overview

SIST EN ISO 14587:2012 is an international standard specifying the characteristics of hexalobular socket raised countersunk (oval) head tapping screws, covering thread sizes from ST2.9 to ST6.3 inclusive. This standard, developed by ISO/TC 2 "Fasteners" in collaboration with CEN/TC 185 “Fasteners”, provides detailed specifications to ensure consistency, quality, and interchangeability of these specialized tapping screws in industrial applications. It supersedes the earlier edition EN ISO 14587:2001 and became effective as a European Standard in February 2011.

These tapping screws are characterized by their raised countersunk oval heads combined with a hexalobular (six-lobed) internal socket design, which enhances torque transfer and reduces cam-out during installation. The document offers comprehensive details on dimensions, material properties, mechanical requirements, and finishing methods.

Key Topics

• Scope and Application
  Defines thread sizes from ST2.9 up to ST6.3 and details screw types including edge treatments and head shapes tailored for specific engineering needs.

• Dimensions and Tolerances
  Precise measurements for various components of the screw such as pitch, head diameter, socket size, thread length, and pitch diameter are standardized following ISO 225 and ISO 7721. Dimensional accuracy ensures compatibility with mating parts and tools.

• Material and Mechanical Properties
  The screws are typically made from heat-treated steel conforming to ISO 2702 requirements, providing strength and durability. Mechanical properties ensure reliability in fastening applications, including resistance to shear and tensile stresses.

• Drive Feature
  The hexalobular internal driving feature specified by ISO 10664 is designed to optimize engagement with drivers, improving torque transmission while minimizing damage to screw heads.

• Finish and Coating
  Surface treatments include electroplated coatings per ISO 4042 and non-electrolytically applied zinc flake coatings according to ISO 10683, offering corrosion resistance and enhanced durability depending on environmental conditions.

• Acceptance and Quality Control
  Inspection procedures for quality assurance follow ISO 3269 to guarantee conformity with accepted product grades and dimensional tolerances as per ISO 4759-1.

• Designation System
  Provides a standardized method for naming tapping screws for clear identification, e.g., "Tapping screw ISO 14587 - ST3,5 × 16 - R" where R indicates a round end type.

Applications

Hexalobular socket raised countersunk (oval) head tapping screws standardized under SIST EN ISO 14587:2012 are widely used in industries requiring reliable and secure fastening solutions, including:

• Automotive manufacturing – Engine assembly, interior fittings, and body components.
• Electronics and electrical equipment – Securing housings and components while allowing controlled torque installation.
• Machinery and equipment – Durable fastening for mechanical parts exposed to vibration and movement.
• Construction and metal fabrication – Assembly of sheet metals and structural panels.
• Precision engineering – Applications demanding high repeatability and minimal damage to fasteners during installation/removal.

This standard supports manufacturers, suppliers, and end-users by providing consistent requirements that facilitate interchangeability and ensure performance in demanding operational environments.
