DIN dimensions from the Berardi catalogue, metric coarse thread. n and t are minimum slot values; the point dimension is explicitly identified as minimum or maximum. Check the drawing for polymer and similar-standard executions before substitution.
Materials, grades, finishes and treatments
| Material | Grade / hardness | Finish |
|---|---|---|
| Steel | 14H | Uncoated; clear zinc plated |
| Stainless steel A1 | To be specified to ISO 3506-3 | To be specified |
| Stainless steel A2 | To be specified to ISO 3506-3 | To be specified |
| Stainless steel A4 | To be specified to ISO 3506-3 | To be specified |
| Brass - similar execution | Alloy to be specified | Plain |
| Polyamide / nylon - similar execution | Not applicable | Natural |
14H denotes a hardness class to ISO 898-5, not a headed-screw strength class. Mechanical properties of stainless and non-ferrous materials must be agreed. Similar executions, including polymers, do not imply dimensional or performance equivalence. Materials and finishes do not define availability: Dueemme confirms supply in the quotation.

Standards, types and application
DIN 551 geometry. ISO 4766 and UNI 6113 are related references: check the edition and drawing for interchangeability. The Bossard catalogue identifies the DIN standard as withdrawn.
Set screws lock by point pressure against the component. They are not intended for tensile loading like headed screws. Assess tightening torque and component strength for the actual joint.
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.
