Description (English):

La présente Norme internationale spécifie les caractéristiques des rondelles plates, série étroite, de grade A, de classes de dureté 200 HV et 300 HV et de diamètre nominal (diamètre nominal de filetage) de 1,6 mm à 36 mm inclus. Les rondelles de classe de dureté 200 HV conviennent à des - vis à tête cylindrique de classes de qualité jusqu'à 8.8 inclus ou en acier inoxydable; - vis à tête cylindrique à six pans creux de classes de qualité jusqu'à 8.8 inclus ou en acier inoxydable; - vis à tête cylindrique à six lobes internes de classes de qualité jusqu'à 8.8 inclus ou en acier inoxydable; - vis autotaraudeuses par déformation, cémentées et trempées à tête cylindrique. Les rondelles de classe de dureté 300 HV conviennent à des - vis à tête cylindrique à six pans creux de classes de qualité jusqu'à 10.9 inclus; - vis à tête cylindrique à six lobes internes de classes de qualité jusqu'à 10.9 inclus. Si des dimensions différentes de celles données dans la présente Norme internationale sont requises, il convient de les choisir parmi celles données dans l'ISO 887. En cas de serrage d'éléments en métal doux ou de larges trous de passage dans la pièce, il convient que l'utilisateur vérifie l'aptitude à l'emploi de ce type de rondelle.

Abstract

Overview

ISO 7092:2000 - Plain washers - Small series - Product grade A - defines the characteristics, sizes and quality requirements for plain (flat) washers, small series, product grade A. The standard covers washers with nominal thread diameters from 1.6 mm to 36 mm and two Vickers hardness classes: 200 HV and 300 HV. It is intended to ensure interchangeability, appropriate mechanical performance and consistent quality of small-series flat washers used with metric fasteners.

Key topics and technical requirements

Size and dimensions: Preferred and non‑preferred dimensions are specified in figures and in Tables 1 and 2 (nominal hole, outer diameter and thickness values for d = 1.6 mm … 36 mm).
Hardness classes: Two classes - 200 HV (suitable for many common screws) and 300 HV (for higher-strength socket-head screws up to class 10.9). Hardness testing follows ISO 6507-1 (Vickers hardness test).
Compatibility with fasteners:
- 200 HV washers: suitable with cylindrical‑head screws (including hexagon‑socket and internal‑lobed types) up to property class 8.8 and stainless fasteners; also for some self‑tapping/case‑hardened screws as noted in the standard.
- 300 HV washers: suitable for higher strength hexagon‑socket and internal‑lobe cylindrical‑head screws up to class 10.9.
Materials and mechanical properties: Materials and mechanical grades are referenced to ISO 3506-1 for stainless steels and to appropriate agreements for other metals.
Surface finish and coatings: Guidance on coatings and avoidance of hydrogen embrittlement is given; electrolytic coatings follow ISO 4042 and non‑electrolytic zinc flake coatings reference ISO 10683.
Tolerances and quality: Dimensional tolerances are referenced to ISO 4759-3; acceptance and receiving inspection procedures follow ISO 3269.
Designation: Standard example format - e.g., “Rondelle ISO 7092‑8‑200 HV” or “Rondelle ISO 7092‑8‑200 HV‑A2” for stainless material.

Applications and users

Practical use cases:

General mechanical assemblies where standardized flat washers are required for load distribution, spacing or protection of mating surfaces.
Small‑series production runs for machinery, automotive components, electronics enclosures and fastener kits.

Who uses ISO 7092:

Design and mechanical engineers specifying fasteners and washers.
Fastener manufacturers and suppliers producing to international tolerances.
Quality inspectors and procurement teams ensuring compliance and interchangeability.
Maintenance engineers and OEMs standardizing replacement parts.
