Key Features

• Genuine OEM Hardware Grade — Manufactured to Wacker Neuson's original torque and thread specifications, so the nut seats and locks exactly as intended for this application.
• Direct Drop-In Replacement — Matches the original thread pitch and dimensions for straightforward installation with no reworking of adjacent components.
• Broad LTN Series Compatibility — Fits LTN5Y and LTN4Y series variants across multiple voltage and regional configurations, covering a wide installed base of Wacker Neuson light towers.
• Secure Locking Function — A properly functioning counter nut holds critical fastened joints against vibration and operational load, preventing loosening during extended run cycles.
• Verified Part Number Traceability — OEM part number 5100007273 is cross-referenced directly against Wacker Neuson's parts documentation, giving you confidence the correct component is on order.

A counter nut — also known as a jam nut or lock nut — is threaded against a primary nut or fastener to prevent it from backing off under vibration or repeated load cycles. In light tower applications, where extended runtime and engine vibration are constant factors, a worn or missing counter nut can allow fastened assemblies to loosen gradually, leading to misalignment, component wear, or mechanical failure. Replacing a damaged or missing counter nut promptly with the correct OEM part restores the integrity of the fastened joint and keeps the surrounding assembly operating as designed.
