Commercial design without an assigned DIN/UNI standard. Breakaway torque, preload and residual-body geometry must be confirmed for the supplied item. Head separation does not certify preload; plan maintenance or removal.
Table dimensions refer to the stated execution. DIN/UNI, polymer and special variants require verification of their own dimensions; they do not automatically inherit reference geometry, weight or performance.
Materials, classes, finishes and treatments
Executions are distinguished by reference, material, class and finish. DIN, ISO and UNI references do not imply dimensional equivalence or availability of every size in each material. Supply and batch documents require quotation confirmation.
| Execution reference | Material | Class / hardness | Documented finishes |
|---|---|---|---|
| Dado a strappo / shear nut | Stainless A2 | To be specified | To be specified |
| Dado a strappo / shear nut | Free-cutting steel | To be specified | To be specified |
“To be specified” is a requirement not established by this selection; it does not imply class 70/80, HV hardness or an automatic finish. Steel property classes do not apply to nylon/polyamide; PA6 and PA66 are distinguished only where stated. For nuts with non-metallic inserts, the material shown is the body material.
