Wacker Neuson 5100008861 Hexagonal Head Cap Screw

The Wacker Neuson 5100008861 is a genuine OEM Hexagonal Head Cap Screw designed for the DPU-series reversible vibratory plate compactors, including DPU80, DPU90, DPU110, and DPU130 models. Sourced directly from Wacker Neuson, this fastener meets the exact specifications required for your machine. It covers an extensive range of DPU variants across both diesel electric-start (Lec) and manual-start (Lem) configurations, as well as reversible (rL) platform builds. When you order part number 5100008861, you get the correct OEM fastener the first time — no guesswork, no substitution.

Key Features

• Correct Thread and Head Geometry — Manufactured to the precise hex head profile and thread specification called out in the Wacker Neuson parts schema, ensuring proper torque transfer and secure clamping without fastener distortion.
• Genuine OEM Part — Supplied as an authentic Wacker Neuson component, holding the same material grade and dimensional tolerance as the original fastener installed at the factory.
• Broad DPU-Series Coverage — Confirmed fitment across DPU80, DPU90, DPU110, and DPU130 reversible plate compactor families, spanning Lec, Lem, rLec, and rLem variants in both standard and US-market configurations.
• Structural Integrity Under Compaction Loads — Reversible plate compactors subject fasteners to sustained vibration and cyclic loading; a worn or missing cap screw can allow critical assemblies to shift, compromising compaction performance and machine alignment.
• Direct Service Replacement — Matches the original fastener's drive size and seating depth, allowing straightforward installation using standard hex tooling with no additional hardware needed.

A hexagonal head cap screw is a precision-threaded fastener used to clamp and secure structural assemblies, guards, drive components, or housings on heavy vibratory equipment. On a reversible plate compactor like the DPU series, fasteners throughout the machine are exposed to constant high-frequency vibration, which places significant stress on thread engagement and clamping force. When a cap screw stretches, strips, or works loose over time, the joint it holds can shift or separate, leading to accelerated wear on adjacent components or, in severe cases, a loss of structural integrity in a load-bearing assembly. Replacing a compromised fastener with the correct OEM-spec part restores the designed clamping force and keeps the machine operating as intended.
