The Wacker Neuson Locking Screw is a genuine OEM component designed for the RC50, RC50p, RC70, RC70p, and RC70vo series compact track loaders, including CAB and ROPS configurations as well as US market variants. As a factory-sourced part, the is manufactured to the exact specifications of the original hardware, ensuring a direct, consistent fit across the full range of compatible RC series machines. This locking screw covers an extensive fitment spread — from standard RC50 and RC70 models through DPF-equipped variants — making it a dependable choice whether you are completing routine maintenance or a targeted repair.
Key Features
- Genuine OEM Thread and Torque Integrity — Manufactured to the exact thread pitch, material grade, and head specification of the original, so the locking screw seats and torques correctly without risk of stripping or backing out.
- Direct Hardware Replacement — Drops straight into the existing threaded bore with no rework; the original hole pattern and drive type are matched precisely to the factory installation.
- Broad RC Series Compatibility — Fits RC50, RC50p, RC70, RC70p, and RC70vo compact track loaders across standard, DPF, CAB, ROPS, and US market configurations.
- Secure Component Retention — A properly functioning locking screw holds attached components in position under the vibration and dynamic loads typical of compact track loader operation; a worn or missing screw allows unwanted movement that accelerates wear on surrounding parts.
- Verified Part Number Traceability — Sourced directly from Wacker Neuson, with part number 5100023664 traceable to the original machine bill of materials for accurate ordering confidence.
A locking screw is a threaded fastener engineered specifically to resist loosening under vibration, shock loads, and cyclical stress — conditions that are constant in compact track loader applications. Unlike standard fasteners, a locking screw uses a thread form, coating, or geometric feature that creates resistance within the threaded joint, keeping the connected component firmly in place throughout operation. When a locking screw fails, backs out, or is missing entirely, the parts it secures can shift, rattle, or separate, leading to accelerated wear on mating components and potential operational faults that can sideline the machine.
