The Wacker Neuson Locking Screw is a genuine OEM locking screw designed for the RD 24-100, RD 27-120, RD 28-120, RD40-130, and RD45-140 series double drum rollers. Sourced directly from Wacker Neuson, this part meets the exact material and dimensional standards of the original component installed at the factory. It covers a wide range of RD series configurations including standard, canopy, open ROPS, and DPF-equipped variants, making it a versatile stocking item for fleets running multiple roller models.
Key Features
- Genuine OEM Thread and Torque Integrity — Manufactured to the precise thread specification and hardness grade of the original, ensuring the screw locks and holds under the vibration loads typical of compaction equipment.
- Direct Drop-In Replacement — Matches the original fastener's dimensions and drive type exactly, so installation requires no re-tapping, drilling, or hardware substitution.
- Broad RD Series Compatibility — Fits RD 24-100, RD 27-120, RD 28-120, RD40-130, and RD45-140 variants, including standard, canopy, open ROPS, and DPF configurations across the .3 and current model generations.
- Maintains Secure Assembly Integrity — A failed or damaged locking screw can allow critical components to shift or come loose during operation; replacing it promptly keeps assemblies properly secured and machine behavior predictable.
- Genuine Wacker Neuson Part — Carries the full Wacker Neuson OEM designation, giving you confidence that the part number, material grade, and fitment data have been validated by the equipment manufacturer.
A locking screw is a fastener engineered to resist loosening under sustained vibration, shock loads, or cyclical movement — conditions that are constant on double drum compaction rollers. It typically incorporates a locking feature through thread geometry, a patch coating, or a mechanical interference fit that prevents the screw from backing out once torqued to specification. When a locking screw wears, strips, or goes missing, the assembly it secures can shift out of position, leading to accelerated wear on surrounding components or an unsafe operating condition. Replacing it with a correctly specified OEM part restores the holding strength the original design depends on.
