Wacker Neuson 5000011531 Screw M12 x 20 8.8 Socket

The Wacker Neuson is a genuine OEM Screw M12 x 20 8.8 Socket designed for a wide range of BPU and DPU reversible vibratory plate compactors, as well as the RD25 tandem roller. As a direct OEM replacement, part is manufactured to the same specifications as the original hardware, ensuring correct fit and function across the full range of compatible machines. This fastener is used across an extensive lineup including BPU 4045A, BPU 5045A, BPU 5545A, and DPU series models ranging from the DPU 4045 through the DPU 6555, as well as the DPU 100-70 heavy-duty reversible plate.

Key Features

• Grade 8.8 Tensile Rating — Manufactured to metric property class 8.8 for the clamping load and shear resistance required in high-vibration compaction equipment.
• Socket Drive Head — Internal hex (socket) head allows secure torque application with standard hex keys or bit drivers, ideal for fastener locations with limited clearance on plate compactor frames.
• Genuine OEM Part — Sourced directly from Wacker Neuson, part number 5000011531 matches the original thread pitch, length, and head geometry specified for these machines at the factory.
• Broad BPU and DPU Compatibility — Confirmed fitment across BPU 4045A, BPU 5545A, DPU 4045, DPU 4545, DPU 5045, DPU 5545, DPU 6055, DPU 6555, DPU 100-70 series plates, and the RD25 tandem roller.
• Vibration Resistance — Designed to maintain clamping integrity under the sustained dynamic loads generated by vibratory compaction equipment, where loose or under-spec fasteners can lead to structural loosening and component damage.

A socket head cap screw is a precision fastener used to clamp and secure structural components and assemblies on compaction equipment. In high-vibration applications like vibratory plate compactors and tandem rollers, fasteners are subjected to constant cyclic loading that can cause under-spec hardware to loosen, strip, or fail prematurely. Using the correct grade and geometry — in this case, an M12 x 20 at property class 8.8 with a socket drive — ensures the joint maintains its designed clamping force throughout the service interval. A missing or damaged fastener in a critical joint can allow components to shift, accelerating wear on surrounding parts and creating unsafe operating conditions.
