Wacker Neuson 5000039191 Hexagonal Head Cap Screw

The Wacker Neuson is a genuine OEM Hexagonal Head Cap Screw designed for BPU and DPU series reversible vibratory plate compactors. This fastener is sourced directly from Wacker Neuson and meets the exact material grade, thread specification, and head geometry required for correct assembly on these machines. Fitment covers a broad range of reversible vibratory plates including the BPU 3545A, BPU 4045A, BPU 5045A, BPU 5545A, DPU 4045H, DPU 4045Y, DPU 4545H, DPU 5045H, DPU 5545H, DPU 6055, and DPU 6555H series. Choosing the correct OEM fastener ensures proper clamp load and torque retention throughout the service life of the compactor.

Key Features

• Correct Thread Form and Head Geometry — Manufactured to the exact thread pitch, shank diameter, and hex head dimensions specified for BPU and DPU plate compactor assemblies, ensuring proper engagement and torque values are met on installation.
• Genuine OEM Part — Supplied by Wacker Neuson as part number 5000039191, this fastener is produced to the same material and hardness grade used during original machine assembly — no substitution guesswork required.
• Wide BPU and DPU Series Coverage — A single verified part number spans gasoline-powered BPU models and diesel-powered DPU models from 35 kN through 65 kN compaction force, simplifying parts sourcing across a mixed fleet.
• Maintains Structural Integrity Under Vibration — Reversible plate compactors generate sustained high-frequency vibration; a fastener with the correct hardness grade and clamping force resists loosening and fatigue cracking over extended operating cycles.
• Critical Torque Retention for Moving Assemblies — Using an incorrect or undersized fastener on a vibratory plate can allow components to shift under load, creating mechanical damage and safety hazards; the correct OEM cap screw preserves designed clamping load.

A hexagonal head cap screw is a fully threaded or partially threaded fastener with a six-sided head designed to be driven by a wrench or socket, providing controlled and measurable torque during assembly. On reversible vibratory plate compactors, these fasteners are used to secure structural and mechanical components that are subjected to continuous high-frequency vibration during operation. When a cap screw is worn, stripped, or replaced with an incorrect grade, the clamped joint can lose preload, allowing parts to shift or separate — leading to accelerated wear, component damage, or machine failure mid-operation. Using the correct OEM fastener with the specified thread form and material grade is the straightforward way to maintain joint integrity and keep the compactor performing as designed.
