Niedrige Sechskantmuttern mit Fase (Typ 0) - Produktklassen A und B (ISO/DIS 4035:2016)

Diese Internationale Norm legt Eigenschaften von flachen Sechskantmuttern (Typ 0) mit Grobgewinde mit Durchmessern von M1,6 bis M64, in Produktklasse A für Durchmesser ≤ M16 und Produktklasse B für Durchmesser > M16, fest.
Flache Muttern, die als Kontermuttern eingesetzt werden, müssen zusammen mit einer normalen oder hohen Mutter montiert werden.
WARNUNG — Flache Muttern (Typ 0) haben im Vergleich zu normalen oder hohen Muttern eine reduzierte Ladekapazität und bieten keinen Widerstand gegen das Abstreifen vom Gewinde (siehe ISO 898-2).

Overview

oSIST prEN ISO 4035:2016 specifies the requirements for hexagon thin nuts (style 0), chamfered, in product grades A and B. These thin hex nuts, standardized by the Slovenski inštitut za standardizacijo (SIST), are intended for applications requiring metric fasteners where a reduced nut height is required. The standard covers coarse thread sizes from M1.6 to M64, with grade A applicable to diameters up to M16, and grade B for diameters above M16. Hexagon thin nuts are commonly used as jam nuts in conjunction with standard or high nuts.

Key Topics

• Product Grades:

  • Grade A: For nominal diameters ≤ M16
  • Grade B: For nominal diameters > M16

• Design Features:

  • Hexagonal shape, style 0 (thin profile)
  • Chamfered corners for improved assembly and handling

• Mechanical Properties:

  • For steel nuts, quenching and tempering in line with ISO 898-2 may be mandatory or optional depending on property class
  • Stainless steel property classes are specified, with updates for corrosion-resistant performance

• Thread Types & Sizes:

  • Covers a range of coarse metric threads from M1.6 to M64
  • Includes both preferred and non-preferred thread sizes

• Loadability & Application Warning:

  • Thin nuts have reduced load capabilities compared to regular or high nuts and are NOT designed to provide resistance to thread stripping
  • Use as jam nuts requires assembly with a regular or high nut for secure locking

• Surface Treatment & Coatings:

  • Electroplating and other coatings as per ISO 4042, ISO 10683, ISO 10684, and passivation for stainless steel according to ISO 16048
  • Surface discontinuities and acceptance inspection covered by ISO 6157-2 and ISO 3269

Applications

Hexagon thin nuts (style 0) are widely used in mechanical engineering, automotive, industrial equipment, and machinery assembly. Their thin profile is advantageous in space-limited assembly situations, where standard height nuts would be impractical.

• Locking Applications:

  • Used as a jam nut in conjunction with a full-height nut to prevent loosening in vibrating environments

• Compact Assemblies:

  • Allows for secure fastening where protrusion needs to be minimized

• Maintenance and Repairs:

  • Ideal for retrofitting existing assemblies requiring additional locking without extensive redesign

• Corrosion-Resistant Applications:

  • Stainless steel versions are suitable for environments that demand enhanced durability against rust and chemicals

Related Standards

To ensure proper selection, performance, and compatibility of hexagon thin nuts, reference to the following standards is recommended:

• ISO 225: Symbols and descriptions of dimensions for fasteners
• ISO 262: Selected sizes for screws, bolts, and nuts
• ISO 724: Basic dimensions for general-purpose metric screw threads
• ISO 898-2: Mechanical properties of fasteners - Nuts
• ISO 965-2 / 965-5: Thread tolerances for screw threads
• ISO 3269: Acceptance inspection for fasteners
• ISO 3506-2: Mechanical properties of stainless steel fasteners
• ISO 4042: Fasteners - Electroplated coatings
• ISO 4759-1: Tolerances for fasteners - Product grades
• ISO 6157-2: Surface discontinuities for nuts
• ISO 10683 / ISO 10684: Coatings for fasteners (zinc flake, hot dip galvanizing)
• ISO 16048: Passivation of stainless-steel fasteners

Adhering to these related fastener standards helps ensure consistent quality, reliability, and interchangeability of hexagon thin nuts in a broad range of applications.
