Key Features
- Genuine OEM Construction — Manufactured to the same material and dimensional tolerances as the original washer, maintaining the clamping integrity required in roller hardware assemblies.
- Internal Tooth Design — The serrated inner teeth bite into the fastener shank to resist loosening under vibration, which is critical in roller equipment subject to continuous operational vibration.
- Direct RW1403HF Fitment — Verified for use on Multiquip RW1403HF roller equipment; installs as a direct drop-in with no modification to the surrounding hardware.
- Vibration Resistance — Tooth engagement prevents fastener back-out during operation, protecting the integrity of the bolted joint and the components it secures.
- Verified OEM Part Number — Ordering by part number 8906604 ensures you receive the exact component specified for this application, eliminating guesswork on fitment.
An internal tooth washer is a locking fastener component that sits between a bolt head or nut and the mating surface. The serrated teeth grip both the fastener and the surface beneath it, creating resistance against rotational loosening caused by vibration and dynamic loads. In roller equipment like the RW1403HF, where mechanical vibration is constant during operation, maintaining secure fastener tension is essential — a loose fastener can lead to component misalignment, accelerated wear, or hardware failure if not addressed promptly.
