< Torque - Tensile force - Push-out - Stainless steel grades >

Direct torque
This value is representative of resistance to unscrewing after ageing. |
 |
|
Indirect torque
In most cases, indirect torque resistance is higher (even much higher) than recommended maximum tightening torque for 8.8 grade bolts with a friction coefficient of 0.20.
The value shown in the data sheets has therefore been limited to the recommended maximum tightening torque for 8.8 grade bolts with a friction coefficient of 0.20.
In other cases, the value shown in the data sheets corresponds to the recommended torque value that is compatible with NUTFIX™ indirect torque resistance. |

< Torque - Tensile force - Push-out - Stainless steel grades >
Tensile force
This value is representative of the force applied after NUTFIX™ assembly.
The tensile force values are provided in the NUTFIX™ data sheets. |

|
|
< Torque - Tensile force - Push-out - Stainless steel grades >
|
Push-out force
This value is representative of the component’s resistance prior to assembly.
The push-out force values are provided in the NUTFIX™ data sheets. |
 |
|
Data related to those tests is provided as a guideline only. These values may vary in accordance with the materials used and implementation conditions. It is recommended that tests be conducted in the actual application conditions. |

Stainless steel: The NUTFIX™ stainless steel range is produced using stainless steel from the austenitic family. This material is recognised for its effectiveness in corrosive environments.
316L Stainless steel: Austenitic A4 stainless steel. The presence of Molybdenum in its composition encourages the auto-generation of a passive coating. This coating offers a natural protection which preserves the intrinsic properties of the component.
HR Stainless steel: The mechanical resistance of these HR stainless steel components facilitates and allows crimping on extremely hard workpieces (up to 90 HRB). The HR range is therefore the optimal solution, in mechanical terms, for stainless steel to stainless steel crimping.
