Drilling and application conditions
| Parameter | Value for the specific execution |
|---|---|
| Minimum thickness of each stacked sheet | 0,6 + 0,6 mm |
| Maximum drilling, two stacked sheets | 1 + 1 mm |
| Drilling speed | 1000-1800 rpm |
Characteristic mechanical data
| Parameter | Value |
|---|---|
| Mt (Nm) | 6,5 |
| Nk (kN) | 7,69 |
| Vk (kN) | 3,86 |
Mt: breaking torque, not installation torque. Nk and Vk: characteristic tensile and shear breaking loads, not allowable design loads. Values apply to the documented execution; connection verification must consider sheets, thicknesses, geometry and installation conditions. Control tightening to compress the seal correctly without damaging it.
