The Wacker Neuson Flange Screw 4x10 is a genuine OEM fastener designed for the BS50-4As, BS60-4As, BS65-4As, BS70-4As, BS72-4As, BS62-4A, and BS68-4A series 4-stroke rammers. Sourced directly from Wacker Neuson, this screw meets the exact thread specification, head geometry, and torque rating called out in the original assembly — ensuring a correct, secure fit without any guesswork. It is a direct like-for-like replacement for the same fastener used on the production line, covering a wide range of BS-series rammer variants including US, CN, and Sunbelt-designated models. When a fastener on your rammer is stripped, corroded, or simply missing, is the correct replacement to restore the assembly to its original specification.
Key Features
- Correct Thread and Head Spec — Manufactured to the exact M4x10 flange screw dimensions specified for Wacker Neuson BS-series rammer assemblies, so it seats and torques properly first time.
- Genuine OEM Part — Supplied by Wacker Neuson, this fastener carries the same material grade and surface treatment as the original, resisting loosening under the high-vibration operating conditions rammers generate.
- Broad BS-Series Fitment — Confirmed fit across BS50-4As, BS60-4As, BS62-4A, BS65-4As, BS68-4A, BS70-4As, and BS72-4As models, including US, CN, and Sunbelt variants.
- Maintains Structural Integrity — A worn or missing flange screw can allow panels, guards, or internal components to shift under load; replacing it promptly keeps the rammer assembly tight and operating as intended.
- Drop-In Installation — Replaces the existing fastener directly with no drilling, re-tapping, or hardware substitution — just remove the old screw and install the new one.
A flange screw is a headed fastener with an integrated washer-like flange beneath the head, which distributes clamping load over a wider surface area and resists loosening under vibration. On a rammer like the Wacker Neuson BS series, where the machine generates sustained high-frequency impact forces, this design is critical — it keeps covers, brackets, and internal assemblies firmly secured throughout operation. When a flange screw is stripped, over-torqued, or lost, the clamping force it provided is gone, and connected components can shift, rattle, or sustain damage over time.
