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 grade 8 nuts 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 grade 8 nuts 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 STUDFIX™ indirect torque resistance. |

< Torque - Tensile force - Push-out - Stainless steel grades >
Tensile force
This value represents the force applied after STUDFIX™ assembly.
The tensile force values are provided in the STUDFIX™ data sheets. |
 |
|
|
< Torque - Tensile force - Push-out - Stainless steel grades >
|
Push-out force
This value represents component resistance before assembly.
The push-out force values are provided in the STUDFIX™ 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 grades |
 Stainless steel: The STUDFIX™ stainless steel range is produced using austenitic stainless steel. This material is recognised for its effectiveness in corrosive environments. |
 HR Stainless steel: mechanical resistance of the components facilitates and permits 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. |
|
|
For extremely harsh environments and specific applications, LA CLUSIENNE-CLUFIX offers custom-made products that are extremely resistant to corrosion. |
