Wacker Neuson 1000022386 Cheese Head Screw M8x25-8.8 DIN912

The Wacker Neuson Cheese Head Screw M8x25-8.8 DIN912 is a genuine OEM fastener designed for the D3.5 Modular Internal Vibrators, TH627 power unit, and WL50 Articulated Wheel Loader. Sourced directly from Wacker Neuson, this part is manufactured to the same standards as the original hardware installed at the factory. Correct thread pitch, shank length, and head geometry ensure the screw seats properly within its mating components without adjustment or rework. Using the correct OEM fastener protects the integrity of the assembly and keeps torque values consistent with the original design specification.

Key Features

• OEM-Specified Grade 8.8 Tensile Strength — Meets the mechanical property requirements of DIN912 for Class 8.8 fasteners, delivering the clamping force the assembly was engineered around.
• Exact M8x25 Thread and Shank Dimensions — Full M8 thread form at 25 mm length drops straight into the existing threaded bore with no chasing or re-tapping required.
• DIN912 Socket Head Profile — The cylindrical cheese head design allows the screw to seat flush in recessed or countersunk boss positions common on Wacker Neuson vibrator and loader assemblies.
• Confirmed Fitment Across Multiple Machine Lines — Verified for D3.5 Modular Internal Vibrators, the TH627 power unit, and the WL50 Articulated Wheel Loader cab assembly.
• Prevents Fastener-Related Assembly Failure — An incorrect or worn screw can lead to joint loosening, vibration-induced fatigue cracking, or component misalignment — the 1000022386 eliminates that risk by restoring the original hardware specification.

A cheese head screw is a socket-drive cap screw with a cylindrical, flat-topped head that provides a large bearing surface while allowing the fastener to sit within a counterbored recess. In equipment like internal vibrators and articulated loaders, these screws secure structural covers, drive housings, and cab components under sustained mechanical load and vibration. When a fastener stretches, strips, or fractures, the joint loses clamping force, which can cause component shift, accelerated wear on mating surfaces, or outright failure of the assembly — making prompt replacement with the correct OEM specification critical.
