DIN 6336 is the governing dimensional standard for clamping handle screw (long). This page sets out the scope of the standard, reproduces the full size table it specifies, and lists the DIN/ISO/ASME cross-references commonly cited in datasheets and drawings.
DIN 6336 — Scope
DIN 6336 specifies the dimensions and tolerances of clamping handle screw (long) — din 6336 / gn 313 (series 044). Material, property class, surface finish and packaging are governed by separate documents in the same standards family (for example ISO 898-1 for the mechanical property classes of bolts and screws).
Tolerance & Product Grades
DIN 6336, alongside the related DIN 6336 / GN 313 entries on this site, specifies product grades (typically A or B for fine work and C for general engineering) and tolerance classes for the controlling dimensions. Choose the grade against the precision your application requires.
Dimensions Specified by DIN 6336
| Thread size | Pitch (mm) | Length L (mm) | Handle length (mm) | Knob diameter (mm) | Reference standard |
|---|---|---|---|---|---|
| M5 | 0.8 | 20 | 45 | 28 | DIN 6336 / GN 313 |
| M6 | 1.0 | 25 | 50 | 32 | DIN 6336 / GN 313 |
| M8 | 1.25 | 30 | 60 | 40 | DIN 6336 / GN 313 |
| M10 | 1.5 | 40 | 70 | 45 | DIN 6336 / GN 313 |
| M12 | 1.75 | 50 | 80 | 50 | DIN 6336 / GN 313 |
Equivalent Standards
Where direct equivalents exist (ISO ↔ DIN, ISO ↔ ASME), they are listed on the parent Clamping Handle Screw (Long) — DIN 6336 / GN 313 (Series 044) page. Always confirm against the dimensions on this page, since some "equivalent" standards differ in tolerances and head geometry.
When to Specify DIN 6336
DIN 6336 is still widely used in European mechanical engineering and as a cross-reference on legacy drawings; its ISO equivalent is preferred for new designs.
