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 | s | m | dc max. |
|---|---|---|---|---|
| 6 | 1 | 10 | 6 | 14.2 |
| 8 | 1.25 | 13 | 8 | 17.9 |
| 10 | 1.5 | 15 | 10 | 21.8 |
| 12 | 1.75 | 18 | 12 | 26 |
| 14 | 2 | 21 | 14 | 29.9 |
| 16 | 2 | 24 | 16 | 34.5 |
Serrations may mark the substrate or coating. They are not a prevailing-torque insert. Smooth flanges and alternative widths are separate designs to confirm; a flange does not replace a washer required by the joint design.
Materials and property classes
| Material | Class / hardness | Configurable range | Supply |
|---|---|---|---|
| Steel to mechanical specification | 8 | M6–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 |
|---|---|---|---|
| Electroplated zinc | Steel to mechanical specification | 8 | M6–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.
