Key Features
- Genuine OEM Serration Integrity — Manufactured with the correct tooth profile and surface hardness to deliver the grip and torque retention a serrated lock washer depends on.
- Direct Hardware Replacement — Drops into the same fastener position as the original, with no modification to surrounding components or fastener stack-up required.
- RD25 Series Fitment — Confirmed fit for the RD25 Hydrostatic Double Drum Vibratory Roller, covering both the 5000008058 and 5000009317 model builds.
- Maintains Clamping Force Under Vibration — The serrated edge bites into mating surfaces to resist loosening — critical on compaction equipment subject to constant vibration cycles.
- Fastener Security Matters — A worn or missing lock washer allows fasteners to back out during operation, which can lead to component misalignment, increased wear on adjacent parts, or machine downtime.
A serrated lock washer is a hardened fastener component with notched teeth on one or both faces that bite into the mating surface and the underside of a bolt head or nut when torqued down. This mechanical bite resists loosening caused by vibration, thermal cycling, and dynamic loads — conditions that are constant on a double drum vibratory roller during compaction work. When a lock washer loses its tension, becomes deformed, or is missing entirely, fasteners in that assembly become vulnerable to backing out, which can allow connected components to shift or fail prematurely.
