Technical Sheets
Foreword of the Manufacturer
To ensure a safe male/female clamping condition, it is important to consider a combination of the following parameters when designing controlled bolt joint assemblies using self locking nuts (HFR):
- Selection of the correct grade of raw material
- Tightening torque (NM)
- Tension in the bolt (KN)
- Prevailing torque (NM)
- Coefficient of friction
- Surface treatment
In order to achieve a security fastening in conformity with industry standards, the 6 points above must be respected. The following technical sheets will aid you in the selection of the self-locking nut adapted to your requirements.
