Wacker Neuson 5000058553 Lock Nut Vm6

The Wacker Neuson Lock Nut Vm6 is a genuine OEM fastener designed for the BS and DS series vibratory rammers, covering a wide range of two-cycle, four-cycle, oil-injected, and diesel rammer models including the BS50-2, BS60-2, BS70-2, BS50-4s, BS60-4s, and DS70 families. Sourced directly through Wacker Neuson's authorized parts supply, this is the same component fitted at the factory, ensuring correct thread engagement and clamping force for the application. Fitment extends across legacy models such as the BS500, BS600, and BS700 series as well as current-generation BS50-2i, BS60-2i, and BS70-2i oil-injected rammers. If you are servicing a BH 22, BH 23, BH 24, or BH 55 gasoline breaker, this nut is also confirmed for those platforms.

Key Features

• Genuine OEM Thread Specification — Vm6 thread profile matches the original fastener exactly, maintaining correct clamping torque without risk of cross-threading or under-torquing.
• Drop-In Replacement — Installs directly in place of the original nut with no additional hardware; correct for both metric and standard rammer configurations across the BS and DS families.
• Broad Rammer Family Coverage — Confirmed fit across BS50-2, BS60-2, BS70-2, BS50-4s, BS60-4s, DS70, DS720, and legacy BS500/BS600/BS700 series, as well as BH 22, BH 23, BH 24, and BH 55 gasoline breakers.
• Locking Design Preserves Joint Integrity — The lock nut's prevailing-torque or locking feature resists loosening under the sustained vibration loads that rammers and breakers generate in normal operation; a missing or worn lock nut can allow fastened assemblies to work loose during use.
• Critical Fastener for High-Vibration Equipment — On rammers and breakers, fastener loosening caused by vibration is a leading source of component damage; replacing worn or stripped lock nuts at each service interval is a straightforward way to maintain structural integrity.

A lock nut is a self-retaining fastener engineered to resist loosening when the assembly it secures is subjected to continuous vibration or dynamic loading. On vibratory rammers and gasoline breakers, internal components generate significant cyclic forces during every stroke, and standard nuts can gradually back off under these conditions. The lock nut's locking mechanism — whether a nylon insert, a distorted thread, or a prevailing-torque profile — maintains clamping force between service intervals. When a lock nut fails or is missing, the joint it secures can loosen progressively, leading to misalignment, accelerated wear on surrounding components, or structural failure of the assembly.
