Overview

ISO 7053:2019 is an international standard specifying the characteristics of hexagon washer head tapping screws. These fasteners are made from steel and stainless steel, covering thread sizes from ST2.2 to ST8, and classified under product grade A. The third edition of this standard provides detailed dimensions, mechanical properties, and designation guidelines for consistent manufacturing and quality control.

This ISO standard ensures that hexagon washer head tapping screws meet strict requirements related to materials, thread specifications, mechanical strength, and corrosion resistance, making it a key reference for manufacturers, engineers, and quality inspectors involved in fastening applications.

Key Topics

  • Scope and Application: Specifies hexagon washer head tapping screws made from steel and stainless steel with thread sizes ST2.2 to ST8 and product grade A.
  • Dimensions and Tolerances: Detailed dimensional requirements including pitch, head size, thread depth, length, and mass per 1,000 pieces as defined in diagrams and tables.
  • Material and Mechanical Properties:
    • Steel fasteners per ISO 2702
    • Stainless steel fasteners meeting ISO 3506-4 standards for corrosion-resistant grades such as A2-20H, A4-20H, and A5-20H
  • Thread Standards: Thread geometry and profile conform to ISO 1478.
  • Coating and Finish:
    • Electroplated coatings as outlined in ISO 4042
    • Non-electrolytically applied zinc flake coatings per ISO 10683
    • Passivation treatments referenced by ISO 16048 for stainless steel
  • Inspection and Quality Assurance: Acceptance inspection procedures aligned with ISO 3269.
  • Designation System: Clear guidelines for product labeling based on thread size, length, material, hardness, and screw end type to facilitate procurement and identification.

Applications

Hexagon washer head tapping screws standardized by ISO 7053:2019 are widely used in:

  • Construction and Building: Providing secure fastening in steel and stainless steel applications where corrosion resistance and structural integrity are critical.
  • Manufacturing and Assembly: Ideal for machinery and equipment assembly requiring precise fastening with reliable thread engagement.
  • Electronics and Electrical Installations: Used where fasteners with defined mechanical properties and corrosion resistance are essential.
  • Automotive and Transportation: Suitable for components exposed to vibration and environmental factors needing durable and standardized fastening solutions.

The specifications in ISO 7053:2019 ensure compatibility across international markets, reducing risks related to part failure and improving product lifecycle performance.

Related Standards

For a comprehensive understanding and implementation of ISO 7053:2019, the following related ISO standards are essential:

  • ISO 1478 – Thread specifications for tapping screws
  • ISO 2702 – Mechanical properties of heat-treated steel tapping screws
  • ISO 3506-4 – Mechanical properties of corrosion-resistant stainless steel tapping screws
  • ISO 4042 – Electroplated coating systems for fasteners
  • ISO 10683 – Zinc flake coating systems (non-electrolytically applied)
  • ISO 4759-1 – Tolerances for fasteners, product grades A, B, and C
  • ISO 8992 – General requirements for bolts, screws, studs, and nuts
  • ISO 3269 – Acceptance inspection of fasteners
  • ISO 16048 – Passivation of corrosion-resistant stainless-steel fasteners
  • ISO 225 – Symbols and descriptions of fastener dimensions

Adherence to these standards alongside ISO 7053:2019 ensures uniformity in quality, dimensions, and mechanical performance of hexagon washer head tapping screws globally.
