Specification summary of DIN 6799 as applied to e-clips (external snap rings): the dimensions the standard fixes, the full size range supplied, and the related designations commonly cross-referenced.
DIN 6799 — Scope
DIN 6799 is "Retaining washers for shafts (E-clips)".
Tolerance & Product Grades
DIN 6799 does not divide e-clips (external snap rings) into product grades. Tolerances are given as limits on the individual dimensions in the table.
Where a general-tolerance class is cited on the drawing instead, it applies to the dimensions not otherwise toleranced.

Equivalent Standards
Where direct equivalents exist (ISO ↔ DIN, ISO ↔ ASME), they are listed on the parent E-Clips (External Snap Rings) page.
Always confirm against the dimensions on this page, since some "equivalent" standards differ in tolerances and head geometry.
Companion Standards
DIN 6799 controls the geometry of e-clips (external snap rings). Surface finish is governed by separate finish standards such as ISO 4042 for electroplating, and corrosion testing by ISO 9227 (neutral salt spray). Mechanical performance is set by the documents specific to this part family — ISO 898-1 and ISO 898-2 apply to bolts, screws, studs and nuts, and not here.
Custom manufacturing · Made to drawing
Need a retaining ring to this standard in a non-standard size?
Parts built to DIN 6799 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 stamping.
Minimum order from 2,000 pieces; samples within 7 days of drawing approval.
