The Wacker Neuson Hexagonal Head Screw M10x40 is a genuine OEM fastener designed for the LTN4Y and LTN5Y series light towers. Sourced directly from Wacker Neuson, this screw meets the exact thread pitch, head geometry, and hardness grade specified for these machines. Confirmed fitment spans multiple LTN4Y and LTN5Y variants, including the LTN4Y 60 Hz, LTN4Y SA, LTN4Y RH, LTN4Y 120V/60Hz, LTN5Y, LTN5Y SA, LTN5Yp, LTN5Yp HD, LTN5Ypk, LTN5Ypa, LTN5Y CH, and LTN5Y UK configurations. When a fastener fails or is damaged during service, replacing it with the correct OEM specification hardware keeps all mating components properly torqued and structurally sound.
Key Features
- Correct Thread and Grade Specification — Manufactured to the exact M10x40 thread form and hardness grade called out in the Wacker Neuson parts schema, so torque values behave as intended during assembly.
- Genuine OEM Hardware — Produced under Wacker Neuson's quality standards, ensuring head dimensions, shank length, and surface treatment match the original screw this part replaces.
- Drop-In Fitment for LTN4Y and LTN5Y Series — Fits the full range of LTN4Y and LTN5Y light tower variants without reworking threads or using non-standard washers or fasteners.
- Structural Integrity Maintained — A correctly spec'd screw holds clamped joints at the load ratings the machine was engineered for; an undersized or wrong-grade substitute can back out or shear under vibration.
- Direct Wacker Neuson Part Number 5100075899 — Order with confidence using the OEM part number to eliminate guesswork and cross-reference errors at the counter or on the jobsite.
A hexagonal head screw is a standard threaded fastener used to clamp two or more components together, with the hex head allowing a wrench or socket to apply the specified torque. In light tower assemblies, fasteners like the M10x40 are typically used in structural, enclosure, and mounting locations where vibration from the engine and generator set places repeated stress on the joint. When a screw stretches, strips, or corrodes, the clamped joint loosens, which can allow components to shift, create excessive wear on mating parts, or cause vibration-related damage over time. Replacing a failed screw with the correct OEM grade and size restores the clamping force the assembly was designed around.
