Specification summary of DIN 705 A as applied to set screw shaft collars: the dimensions the standard fixes, the full size range supplied, and the related designations commonly cross-referenced.
DIN 705 A — Scope
The table below lists the dimensions catalogued for set screw shaft collars under DIN 705 A. The scope of DIN 705 A itself is not summarised here — where a figure matters, confirm it against the published document.
Tolerance & Product Grades
Product grade is a concept from dimensional fastener standards and does not apply to DIN 705 A. Tolerances for this part are the limits shown against each dimension in the table.

Equivalent Standards
Where direct equivalents exist (ISO ↔ DIN, ISO ↔ ASME), they are listed on the parent Set Screw Shaft Collars page.
Always confirm against the dimensions on this page, since some "equivalent" standards differ in tolerances and head geometry.
Companion Standards
A complete specification for set screw shaft collars normally cites several documents: one for the geometry, one for the material or mechanical properties, and one for the finish. DIN 705 A is one of them, not all of them.
Custom manufacturing · Made to drawing
Need a shaft collar to this standard in a non-standard size?
Parts built to DIN 705 A are already in the catalog, so a special is usually a variation on existing tooling rather than a new design — which is what keeps the cost down. Made by thread turning or turning.
Minimum order from 2,000 pieces; samples within 7 days of drawing approval.
