8171338 Nut — Volvo FMX FE Series trucks — FH400

This is a standard M20 nut, a common fastener used in various assembly and maintenance applications on Volvo trucks. Manufactured to precise industrial standards, it provides reliable clamping force and resists loosening under vibration better than a worn or cross-threaded nut. Operators might notice loose components or hear rattling if this nut fails to maintain its grip.

Failure Symptoms

The primary symptom of a failing nut is a loss of clamping force, leading to looseness in the assembled components. If left unaddressed, this can cause excessive wear on mating parts, misalignment, or noise from the unsecured assembly. The worst consequence is the potential failure of the secured component due to vibration and stress.

Installation Tip

Always start the nut by hand to ensure it is threading correctly and avoid cross-threading. Use the appropriate size wrench or socket to tighten securely.

Service Note

Inspect the bolt or stud threads for damage or wear before installing a new nut; replace the fastener if necessary.
