DIN 6336 specifies the dimensions and tolerances for clamping handle screw (short). The full dimensional table is reproduced below, followed by the DIN, ISO and ASME parts that match or supersede it.
- Standard
- DIN 6336
- Product
- Clamping Handle Screw (Short) — DIN 6336 / GN 313 (Series 042)
- Governing standards
- DIN 6336 / GN 313
Equivalence between national standards is dimensional, not always metallurgical. Check the property class separately when substituting.
The table below lists the dimensions catalogued for clamping handle screw (short) under DIN 6336. The scope of DIN 6336 itself is not summarised here — where a figure matters, confirm it against the published document.
DIN 6336 — Scope

Tolerance & Product Grades
Product grade is a concept from dimensional fastener standards and does not apply to DIN 6336. Tolerances for this part are the limits shown against each dimension in the table.
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 |
Companion Standards
A complete specification for clamping handle screw (short) — din 6336 / gn 313 (series 042) normally cites several documents: one for the geometry, one for the material or mechanical properties, and one for the finish. DIN 6336 is one of them, not all of them.
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.
Custom manufacturing · Made to drawing
Need a bolt to this standard in a non-standard size?
Parts built to DIN 6336 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 cold heading or hot forging.
Minimum order from 2,000 pieces; samples within 7 days of drawing approval.

Applications & Industries
What Clamping Handle Screw are specified for, industry by industry. Stocked from M5 to M12.
Industries that specify Clamping Handle Screw
-
Maintenance & MRO
Stocked replacements matched to an existing property class, thread and finish.
-
Food, pharma & cleanroom
Stainless assemblies that are washed down, where the finish matters as much as the strength.
-
Machine building & OEM
The default fastener on production equipment: covers, brackets, motor mounts and sub-assemblies tightened to a specified torque.
-
Automotive & transport
Chassis, driveline and body fixings that see vibration and are assembled to a controlled preload.
-
Steel fabrication
Bolted connections in frames, enclosures, walkways and weldments, on the bench and on site.
-
Energy & infrastructure
Tower, pipework, switchgear and plant fixings specified for long service life and inspectable joints.
Typical applications
- assemblies that are dismantled for service and re-torqued
- joints where the property class is stated on the drawing
- clamping two machined faces to a calculated preload
- bolting brackets, motors and gearboxes to a frame
Service conditions to specify against
- Marine and coastal
- Available in A4 (316) stainless for chloride exposure — coastal structures, pool halls, water treatment and deck hardware, where A2 will eventually pit.
- High load
- Supplied in ISO 898-1 property classes, so the joint can be designed to a stated proof load and tightened to a calculated torque rather than by feel.
- Torque and preload
- The joint is designed around bolt tension, so lubrication, coating and the friction coefficient all change the torque figure — state them together.
Where to use something else
- Do not use a machine thread into unthreaded sheet or timber; use a tapping screw, rivet nut or insert made for that parent material.
