Overview

SIST EN ISO 7046-1:2011 is a European and international standard specifying the requirements for countersunk flat head screws with common head styles featuring type H or type Z cross recesses. These screws are of product grade A and made from steel with a property class of 4.8, covering thread sizes from M1.6 to M10 inclusive. Developed by ISO Technical Committee ISO/TC 2 “Fasteners” in collaboration with CEN/TC 185, this standard ensures consistency, quality, and interoperability in manufacturing and usage of these screws across various industries.

This standard supersedes the previous edition ISO 7046-1:1994 and aligns with relevant ISO fastener standards, providing detailed specifications on dimensions, mechanical properties, tolerances, cross recess types, and surface finish requirements. It supports engineering and manufacturing efforts where precision and reliability in fasteners are critical.

Key Topics

  • Scope & Application
    Defines countersunk flat head screws with type H or type Z cross recesses in steel of property class 4.8, intended mainly for mechanical assembly where countersunk heads provide a flush finish. Applicable for thread diameters M1.6 to M10.

  • Dimensions and Tolerances
    Provides detailed dimensional data including head size, thread pitch, recess depth and diameters, reference to ISO 225 for symbolic dimensions, and tolerances consistent with ISO 4759-1 and ISO 965-2.

  • Cross Recess Types
    Covers two cross recess styles:

    • Type H (series 1 deep)
    • Type Z (series 1, deeper penetration), with precise specifications on penetration depth, width, and shape per ISO 4757.
  • Mechanical Properties and Material
    Defines screws made of steel complying with property class 4.8 as per ISO 898-1, ensuring adequate strength and reliability for typical fastening applications.

  • Surface Finish and Coatings
    Screws must meet electroplating and coating requirements defined in ISO 4042. Surface integrity limits and acceptance inspections refer to ISO 6157-1 and ISO 3269 respectively.

  • Designation System
    Clear format for designating screws including the thread size, length, property class, and recess type (e.g., “ISO 7046-1 - M5 × 20 - 4.8 - Z”), facilitating unambiguous communication and ordering.

Applications

SIST EN ISO 7046-1:2011 screws are widely used in industries requiring flush fastening solutions with precise mechanical performance such as:

  • Automotive and Transportation
    For assembling components where countersunk screws ensure aerodynamic surfaces and avoid snagging.

  • Consumer Electronics and Appliances
    Where aesthetic flat finishes and secure fastening are necessary.

  • Machine Building and Engineering
    In applications requiring controlled mechanical properties and adherence to standardized thread sizes and profiles.

  • Construction and Metal Fabrication
    Ensuring structural reliability with consistent fastener quality.

  • Maintenance and Repair
    Standardized screws simplify replacements and ensure compatibility with existing assemblies.

The standardization supports global supply chains by harmonizing requirements and reducing the risk of incompatibility and quality issues.

Related Standards

SIST EN ISO 7046-1:2011 interfaces with several complementary ISO standards to provide a comprehensive framework for screw specification and quality control:

  • ISO 261 - Metric screw threads: general plan
  • ISO 898-1 - Mechanical properties of carbon steel and alloy steel fasteners
  • ISO 965-2 - Thread tolerances for metric screws
  • ISO 4757 - Cross recess definitions for screws
  • ISO 4759-1 - Tolerances for fasteners product grades
  • ISO 4042 - Electroplated coatings for fasteners
  • ISO 6157-1 - Surface discontinuities for bolts and screws
  • ISO 3269 - Acceptance inspection for fasteners
  • ISO 225 - Symbols and dimensions for bolts and screws

Understanding these related standards enhances compliance and ensures optimal selection, manufacturing, and inspection processes for countersunk flat head screws.
