The Wacker Neuson Cylinder Head Screw is a genuine OEM cylinder head screw designed for the RD7 and RD10 series double drum rollers, including the RD7H, RD7Heh, RD7Hf, RD7Hehf, RD7Yeh, RD7Yehf, RD7Af, RD7Hfb, RD7Hehfb, RD7Yehfb, RD7Afb, and RD10Yehf series machines. As a genuine Wacker Neuson part, is manufactured to the same exacting standards as the original hardware, ensuring a correct, secure fit in the cylinder head assembly. This is the screw specified for LRC and HRC variants across the RD7 and RD10 families, covering an extensive range of configurations so you can order with confidence. Verify your model number against the fitment list before ordering to confirm compatibility.
Key Features
- Correct Thread Engagement: — Engineered to the exact thread pitch and torque specification required for secure cylinder head clamping — no guesswork on fitment.
- Genuine OEM Hardware: — Sourced directly from Wacker Neuson, this screw meets the same material hardness and tensile strength standards as the original production fastener.
- Broad RD7 and RD10 Coverage: — Fits a wide range of RD7 and RD10 double drum roller variants, including HRC, LRC, H, Heh, Hf, Af, and fb configurations.
- Cylinder Sealing Integrity: — A correctly torqued and properly spec'd cylinder head screw maintains the clamping load needed to preserve head gasket compression and prevent combustion leaks.
- Direct OEM Replacement: — Replaces the original hardware on a like-for-like basis, reinstalling the same way the factory screw came out with no adaptation needed.
A cylinder head screw is a critical fastener that clamps the cylinder head firmly against the engine block, maintaining the compression seal created by the head gasket. These screws must sustain precise clamping force under the thermal cycling and vibration loads generated during engine operation. When a cylinder head screw stretches, strips, or fails, the head gasket loses clamping pressure, leading to compression loss, coolant intrusion, or combustion gas leakage — all of which can cause serious engine damage if left unaddressed. Using the correct OEM-specified replacement ensures the fastener performs as designed throughout the engine's service life.
