Wacker Neuson 5100006657 Screw M12x40

The Wacker Neuson Screw M12x40 is a genuine OEM fastener designed for the RD7H, RD7Yeh, RD7Af, RD7Hf, RD7Hehf, RD7Yehf, RD7Hfb, RD7Hehfb, RD7Yehfb, RD7Afb, and RD10Yehf series double drum rollers. Sourced directly from Wacker Neuson, this screw matches the exact thread pitch, length, and material grade specified for these machines, ensuring a flush, properly torqued installation every time. With coverage across LRC and HRC variants in the RD7 and RD10 families, part number is a straightforward, single-SKU solution for a wide range of machines in your fleet.

Key Features

• Correct Thread Specification: — M12x40 thread dimensions match the OEM-specified pitch and length, so the fastener seats and torques correctly without thread damage or misfit.
• Genuine Wacker Neuson OEM Part: — Manufactured to the same material grade and hardness as the original, ensuring the screw holds rated clamp force under the vibration loads typical of drum roller operation.
• Broad RD7 and RD10 Series Coverage: — A single part number covers RD7H, RD7Heh, RD7Yeh, RD7Af, RD7Hf, RD7Hehf, RD7Yehf, RD7Hfb, RD7Hehfb, RD7Yehfb, RD7Afb LRC/HRC variants, and the RD10Yehf LRC.
• Vibration-Resistant Fastening: — Compaction equipment subjects fasteners to continuous high-frequency vibration; using the specified OEM screw maintains proper joint integrity and prevents loosening over extended service cycles.
• Drop-In Replacement: — Identical dimensions to the original mean no drilling, re-tapping, or hardware modification — the screw installs directly into existing threaded bores using standard M12 tooling.

An M12x40 screw is a metric hex fastener used to secure structural and functional assemblies on compaction equipment — in this application, across multiple drum roller variants in the Wacker Neuson RD7 and RD10 families. Fasteners like this one maintain the clamping force that holds critical components in alignment under the sustained vibration generated during soil and asphalt compaction. When a screw of this type stretches, strips, or fails, the joint it secures can shift or separate, leading to accelerated component wear, misalignment, or potential mechanical failure mid-operation. Replacing a worn or damaged screw with the correct OEM part, 5100006657, restores the designed clamping load and keeps the assembly performing as intended.
