The Wacker Neuson 5200020272 Nut is a genuine OEM fastener designed for the LTN4Y and LTN5Y series light towers and the APT4S and APT4T series self-priming pumps. As a direct OEM replacement, this nut is manufactured to the same specifications as the original hardware installed at the factory, ensuring correct thread engagement and clamping performance. It fits a wide range of configurations across both product families, including cold-weather, surge brake, electric brake, and skid-mounted variants. Confirm your model number before ordering to ensure this is the correct fastener for your application.
Key Features
- Genuine OEM Thread Specification — Manufactured to exact thread pitch and grade as the original, ensuring proper torque load and secure fastening without risk of stripping or misthread.
- Drop-In Hardware Replacement — Installs directly in place of the original nut with no rework or thread chasing required on properly maintained hardware.
- Broad Fitment Across Two Product Families — Confirmed for LTN4Y and LTN5Y light towers and APT4S and APT4T pump units, including cold-weather, surge brake, electric brake, and skid configurations.
- Structural Integrity Under Field Conditions — A correctly fitted nut maintains critical joint tension on light tower masts and pump assemblies; a worn, damaged, or incorrect fastener can allow components to loosen under vibration, compromising both function and stability.
- Safety-Critical Fastener — Used in structural and mechanical assemblies on elevated light towers and pressurized pump systems, making correct specification and proper torque essential for safe operation.
A nut is a threaded fastener that mates with a bolt or stud to clamp components together in a secure mechanical joint. On light towers, fasteners like this one hold structural and mechanical assemblies in position through the vibration and stress of transport and extended field operation. On pump units, they secure fittings, brackets, and covers exposed to pressure and operational movement. When a nut is damaged, cross-threaded, or missing, the joint it holds can loosen or fail entirely, leading to component movement, fluid leaks, or structural instability in the machine.
