Selecting screws, nuts and washers - the key to reliable installations

The proper selection of fasteners is the basis for the durability of the installation.   It is crucial to take into account the working conditions and loads . Attention should be paid to the material of manufacture and strength class. Dimensions and type of thread are also important. Selecting the appropriate washers ensures even distribution of stress.

Our experience shows that it is worth using fasteners of the same class. This ensures the strength consistency of the entire connection. In the case of installations exposed to vibration, we recommend self-locking nuts. For detachable connections, spring washers work well.

1. Determine operating conditions and required loads
2. Choose the right material and strength class
3. Choose the right dimensions and thread type
4. Use appropriate washers and nuts
5. Take into account the specifics of the installation (e.g. vibration resistance)

Many customers ask us about the possibility of using substitutes. In some cases, it is possible. However, we always recommend consulting our specialists. This will help avoid potential problems in the future. The safety and reliability of the installation are our priority.
