Wacker Neuson 5000129420 Socket Head Cap Screw

The Wacker Neuson is a genuine OEM Socket Head Cap Screw designed for a wide range of Wacker Neuson gasoline breakers and reversible vibratory plate compactors. This fastener is a direct-fit replacement used across the BH 22, BH 23, BH 24, BH 40, BH 55, and BH 65 gasoline breaker families, as well as the DPU 4045, DPU 4545, DPU 5045, DPU 5545, DPU 6055, DPU 6555, DPU 80L, DPU 90L, and DPU 110L reversible vibratory plate compactor series. As a genuine Wacker Neuson part, the is manufactured to the exact material grade, thread specification, and head geometry required by the original equipment. Keeping the correct fastener in place ensures that critical assemblies remain properly torqued and secure through the vibration-intensive operating cycles these machines demand.

Key Features

• Genuine OEM Material Grade — Manufactured to the exact alloy and hardness specification required for high-vibration breaker and compactor assemblies, maintaining correct clamp load under continuous mechanical stress.
• Exact Thread and Head Geometry — Matches the original socket head profile and thread form, seating correctly with the appropriate hex key drive without risk of thread stripping or head rounding.
• Broad Cross-Family Fitment — A single part number covering BH-series gasoline breakers (BH 22 through BH 65) and DPU-series reversible vibratory plate compactors (DPU 4045 through DPU 110L), simplifying parts inventory across multiple machines.
• Structural Integrity Under Vibration — In breakers and plate compactors, loose or incorrect fasteners can allow critical components to shift, accelerating wear and causing assembly failure; the correct OEM screw maintains the torque retention needed to prevent this.
• Drop-In Replacement — Installs using standard hex key tooling with no rework, thread chasing, or modification to the receiving bore, keeping service time to a minimum.

A socket head cap screw is an internally driven threaded fastener with a cylindrical head and a hexagonal socket recess, designed to be tightened with an Allen or hex key. In high-vibration equipment such as gasoline breakers and diesel-powered reversible plate compactors, these screws secure structural covers, guide components, and internal assemblies that are subjected to sustained impact and oscillating forces during every operating cycle. When a socket head cap screw stretches, corrodes, or shears, the assembly it holds can loosen or separate, creating both a mechanical failure and a safety hazard. Replacing a damaged or missing screw with the correct OEM-specification fastener restores the designed clamp load and keeps the machine operating as intended.
