Key Features
- OEM Thread and Torque Specification — Manufactured to Wacker Neuson's exact thread pitch and head geometry, ensuring the screw seats and torques correctly against the cylinder head surface without risk of stripping or improper clamping.
- Direct Drop-In Installation — Matches the original mounting hole pattern and head profile on the cylinder assembly, so no reworking or adjustment is needed during fitment.
- Broad RD7 and RD10 Series Coverage — Compatible across a wide range of RD7H, RD7Yeh, RD7Af, RD7Hf, RD7Hehf, RD7Yehfb, and RD10Yehf series configurations in both LRC and HRC variants.
- Maintains Cylinder Head Integrity — A correctly torqued cylinder head screw is critical to maintaining compression and preventing coolant or combustion gas leaks — a worn or damaged screw can compromise the entire cylinder head seal.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, part number 5100006622 carries the same material grade and dimensional standards as the screw originally installed at the factory.
A cylinder head screw is a fastener that clamps the cylinder head firmly against the engine block, compressing the head gasket to create a sealed combustion chamber. These screws must maintain precise clamping force under extreme heat and pressure cycling — if a screw is worn, stretched, or incorrectly torqued, the head gasket can fail, leading to compression loss, overheating, or fluid contamination in the combustion chamber. Replacing a damaged or compromised cylinder head screw with the correct OEM part restores proper clamping integrity and protects the engine from further damage.
