Technical drawing and dimensional range
Reference sizes are listed in the table. Other diameters, pitches, materials and finishes are available on request, subject to an agreed supply specification.
Dimensions in mm. Identification drawing, not a manufacturing drawing.
| M | Pitch P | e | h | d2 | m |
|---|---|---|---|---|---|
| 4 | 0.7 | 19 | 9.5 | 7 | 3.9 |
| 5 | 0.8 | 25 | 12 | 9.5 | 5.3 |
| 6 | 1 | 31.5 | 16 | 11.5 | 6.5 |
| 8 | 1.25 | 37.5 | 19 | 14.5 | 8.3 |
| 10 | 1.5 | 49.5 | 24 | 18.5 | 10 |

| 16 | 2 | 71.5 | 36.3 | 27.5 | 15 |
Do not confuse the cast DIN 315 design with stamped American-type wings or the commercial UNI 5448 series: shape and envelope can differ. Do not apply tool-tightened hexagon-nut torque values.
Materials and property classes
| Material | Class / hardness | Configurable range | Supply |
|---|---|---|---|
| A2 stainless steel | To be specified | M4–M16 | On request |
Other materials and specifications on request
For requirements beyond the tabulated combinations, enquire about aluminium, brass, nylon, duplex, superduplex or an ASTM specification. Alloy or grade, dimensions, mechanical requirements and finish are defined for the enquiry; the geometric reference does not automatically imply conformity with the product standard.
Enquire about another material or ASTM specification
Finishes and treatments
| Finish | Material | Class / hardness | M |
|---|---|---|---|
| Plain / as manufactured | A2 stainless steel | To be specified | M4–M16 |
Select the finish for the material/property-class combination. Hydrogen relief and lubrication are separate process requirements, not certificates and not implied by the coating name.
