ISO 6410-2:1993

Overview

ISO 6410-2:1993 is an international standard published by the International Organization for Standardization (ISO). It forms part of the ISO 6410 series which standardizes the representation of screw threads and threaded parts in technical drawings, with Part 2 specifically focused on screw thread inserts. The standard provides comprehensive guidelines on how to depict screw thread inserts in technical documentation, ensuring clear and consistent communication across industries involved in the design, manufacturing, and installation of threaded components.

This standard outlines methods for detailed, conventional, and simplified representations, as well as the correct designation and dimensioning of screw thread inserts on mechanical engineering drawings.

Key Topics

• Definition and Purpose of Screw Thread Inserts: Clarifies the types and variety of screw thread inserts, acknowledging their different forms and materials depending on application and manufacturer.
• Methods of Representation:
  • Detailed Representation: Shows the true shape of screw thread inserts, recommended primarily for illustrations and catalogs rather than technical drawings.
  • Conventional Representation: Establishes standardized visuals derived from ISO 6410-1, offering clarity and uniformity in the depiction of inserts in engineering documents.
  • Simplified Representation: Demonstrates the essential features while omitting unnecessary detail, supporting easy-reading and efficient documentation, and is encouraged for most technical drawings.
• Rules for Depiction: Specifies how screw thread inserts should be drawn in sectional views, including the use of continuous thick lines and the omission of hatching and certain internal diameters in the assembled condition.
• Designation and Dimensioning: Details the standardized nomenclature for screw thread inserts, using thread designation followed by “INS” (e.g., M30 x 1.5 INS), and provides guidance when specific standards do not exist for a given insert type.

Applications

ISO 6410-2:1993 is widely applicable in fields that depend on the precise communication of mechanical component interfaces, especially within:

• Mechanical Engineering: Ensures all parties - from designers to manufacturers - depict screw thread inserts consistently in technical drawings.
• Manufacturing: Aids in process planning, quality control, and part verification by clearly identifying insert requirements and specifications.
• Product Documentation: Supports the creation of catalog materials and assembly instructions by distinguishing between detailed and simplified representations depending on the document’s purpose.
• Supplier and Procurement Communication: Standardized graphical representation facilitates accurate bidding, manufacturing, and quality assurance when sourcing or producing threaded parts.
• Training and Education: Used as a reference in engineering education for teaching industry best practices in technical drawing of threaded components.
