DIN dimensions from the Berardi catalogue, metric coarse thread. ISO references may have dimensional differences: do not use this table as an ISO dimensional table. Polymer executions require drawing verification. The PH column applies only to Phillips H; the Pozidriv Z execution must be specified separately.
Materials, grades, finishes and treatments
| Material | Grade | Finish |
|---|---|---|
| Steel | 4.8 | Uncoated; black zinc plated |
| Stainless steel A2 | To be specified to ISO 3506-1 | To be specified |
| Stainless steel A4 | To be specified to ISO 3506-1 | To be specified |
| Polyamide / nylon - similar execution | Not applicable | Natural |
Mechanical grades refer to the material and actual execution: do not apply class 4.8 to stainless steels or polymers. Specify the stainless grade, non-ferrous alloy, coating and documentation in the enquiry. Materials and finishes do not define availability: Dueemme confirms supply in the quotation.

Standards, executions and application
The table describes DIN 7985; ISO 7045 and UNI 7687 are related references. Agree the required standard and check its edition, geometry and mechanical requirements before substituting a screw.
Verify the mating surface and head contact. Tightening torque depends on material, coating, friction and the assembled component.
H (Phillips) and Z (Pozidriv) drives are documented for stainless executions. State the required drive; the tools are not interchangeable.
Configure your enquiry
Select the diameter and enter the required length in the specifications, together with material, finish and quantity. Dueemme will confirm supply in its quotation.
The size you need, including custom specifications
Other diameters, lengths, materials and finishes can be assessed on request. For dedicated production, we agree geometry, requirements and minimum quantities with the customer.
