TS EN ISO 6410-2

TS EN ISO 6410-2 addresses the representation of screw thread inserts in technical drawings, with a focus on inserts associated with internal surfaces such as bores. A screw thread insert is a separate threaded component used where the thread is not formed directly in the parent material. In engineering drawings, showing this clearly matters because the drawing must communicate both the functional thread and the fact that it is provided by an inserted element rather than by the base part itself.

How the drawing representation is organised

The standard provides methods for depicting these inserts on technical drawings. In general drafting practice, threaded features are read together with views, sections and dimensions, so the representation must be unambiguous enough for manufacturing and inspection. Screw thread inserts are commonly used where repairability, wear resistance, improved thread performance in softer materials, or repeated assembly and disassembly are important. The drawing convention helps the reader distinguish the insert from the surrounding component geometry.

Position within the ISO 6410 series

The ISO 6410 family is concerned with consistent graphical representation of screw threads and threaded parts. This part complements the general thread representation rules by clarifying how insert-type threaded elements are shown. In practice, that supports clearer communication between part drawings, assembly documentation and manufacturing records, especially where the internal thread is created through a separate threaded insert rather than directly in the base material.
