The Wacker Neuson Locknut is a genuine OEM component designed for the LTN4Y and LTN5Y series light towers, including variants such as the LTN4Y 60 Hz, LTN4Y SA, LTN4Y RH, LTN4Y 120V/60Hz, LTN5Y, LTN5Y CH, LTN5Y UK, LTN5Yp, LTN5Yp HD, LTN5Ypk, and LTN5Ypa. Sourced directly from Wacker Neuson, this locknut is manufactured to the exact specifications of the original part — ensuring a correct, secure installation every time. As a genuine OEM replacement, it carries the same part number and tolerances as the hardware your machine left the factory with, so there is no guesswork around fit or function. Verify your model against the fitment list above before ordering to confirm compatibility.
Key Features
- OEM Thread Integrity — Manufactured to Wacker Neuson's original torque and thread specification, so the locknut engages and holds with the same clamping force as the factory-installed hardware.
- Drop-In Replacement — Matches the original fastener's thread pitch, diameter, and locking mechanism for a direct swap with no fitting adjustments needed.
- Broad LTN Series Fitment — Confirmed for LTN4Y and LTN5Y series light towers across multiple configurations, including 60 Hz, 120V/60Hz, SA, RH, CH, UK, HD, and pk variants.
- Secure Vibration Resistance — The locking design prevents loosening under the continuous vibration common in towable light tower operation, maintaining the integrity of the assembly it secures.
- Genuine Wacker Neuson Part — Carries the authentic Wacker Neuson part number 5100007058, giving you confidence that you are installing the correct hardware — not a generic substitute.
A locknut is a fastener engineered to resist loosening under vibration, dynamic loads, and repeated thermal cycling — conditions that standard nuts can fail to handle over time. In light tower applications, locknuts are used throughout the mast, frame, and component mounting points to keep critical assemblies securely in place during transport and operation. When a locknut wears, strips, or loses its locking tension, the joint it secures can work loose, leading to misalignment, component damage, or an unsafe operating condition — making timely replacement with the correct part essential.
