FAQ

What exactly is the task / function of the component?
The fastening element provides clamping force, positioning or securing of a mechanical connection and is therefore often a function-critical assembly element. The thread, material and strength determine the load-bearing capacity of the connection.

How do you recognize a defect / typical symptoms?
Typical damage includes corrosion, damaged threads, plastic elongation, rounded heads or lost preload with subsequent movement of the assembly. In the case of spacers and shims, run-in marks and dimensional loss are also relevant.

How do you check / test the component?
The thread, head and bearing surfaces, length, diameter, pitch and, if necessary, the tightening torque or residual clamping force are checked. A multimeter is not useful here; visual inspection, dimensional check and proper fit are decisive.

When should it be replaced?
The part should be replaced in the event of corrosion, deformation, damaged threads or if the manufacturer specifies single use. After destructive disassembly or unclear strength, replacement is preferable.

How do you check compatibility?
The OEM number, thread dimension, length, pitch, head or molded part geometry, material and surface coating are important. The underhead support, strength class and installation location must also match.
