When only OEM quality will do, this component delivers the correct spec every time.
Key Features
- Genuine OEM Material Grade — manufactured to Bomag's exact hardness and surface finish specifications, ensuring the washer delivers proper tension retention under the vibration and heat loads common in screed operation
- Direct-Fit Replacement — matches the original inner diameter, outer diameter, and tooth profile of the factory-installed washer, so this part installs cleanly without rework or shimming
- Confirmed S20E Screed Fitment — verified for the Bomag S20E screed, taking the guesswork out of parts sourcing for this application
- Fastener Security — a correctly functioning locking washer prevents fastener back-out caused by screed vibration; a worn or missing washer can allow critical bolted connections to loosen progressively during operation
- Genuine OEM Traceability — carries Bomag part number 07438005, making it straightforward to cross-reference against service manuals and parts catalogs for confident ordering
A locking washer is a small but essential fastener component that sits between a nut or bolt head and the mating surface to resist loosening caused by vibration, thermal cycling, and dynamic loads. In a screed like the S20E, where the entire assembly is subject to continuous vibration during paving operations, maintaining tight and secure bolted joints is critical to consistent screed performance and surface quality. When a locking washer fails, deforms, or is omitted, the associated fastener can work loose over time, leading to misalignment, component wear, or unplanned service interruptions.
