The Wacker Neuson is a genuine OEM Lock Washer A6 designed for a broad range of Wacker Neuson compaction and cutting equipment, including the RD7, RD10, and RD25 tandem rollers, DPU 2440H, DPU 4045H, DPU 5045H, DPU 6055, and DPU 7060 reversible vibratory plate compactors, the DPS 1850H single-direction vibratory plate, and the BTS 11 and BTS 13 cut-off saws. Sourced directly from Wacker Neuson, this is an authentic OEM part manufactured to the same specification as the original hardware installed at the factory. With fitment spanning tandem rollers, heavy-duty diesel reversible plates, and cut-off saws, part number is a high-utility fastener component worth keeping in your service stock.
Key Features
- Genuine OEM Hardness and Temper Rating — Manufactured to Wacker Neuson's specified hardness grade for lock washers, ensuring correct clamping load and resistance to loosening under vibration.
- Direct-Fit Hardware Replacement — Matches the A6 designation exactly, dropping into existing fastener assemblies without resizing, shimming, or modification to mating hardware.
- Wide Compaction Equipment Compatibility — Fits RD7 and RD10 tandem rollers, DPU 2440H through DPU 7060 reversible vibratory plates, and DPS 1850H single-direction plates across multiple serial configurations.
- Also Fits BTS Cut-Off Saws — Confirmed fitment on the BTS 11 and BTS 13 gasoline cut-off saws, making this a versatile service part across machine families.
- Vibration-Resistant Locking Geometry — The lock washer profile maintains fastener preload in high-vibration operating environments, preventing bolt back-out that can lead to component loosening or misalignment.
A lock washer is a hardened fastener component placed beneath a nut or bolt head to resist rotational loosening caused by vibration, shock loads, or thermal cycling. In compaction equipment and cut-off saws — machines that operate under sustained high-frequency vibration — standard flat washers can allow fasteners to gradually back out, leading to loose assemblies, component damage, or unplanned service interruptions. The correct lock washer maintains proper clamping force at the joint, keeping critical assemblies secure through normal operating loads. Using the correct OEM-specified size and grade, such as the A6 designation of part 5000012971, ensures the washer functions as engineered within its fastener stack.
