The Multiquip 58329 is a genuine OEM Lock Washer 14mm designed for Multiquip RAMMAX walk-behind rollers, including the RW1403HF, RW1404, RW1404MR, RW1504HF, and P33/24 series. As a direct Multiquip OEM part, 58329 is manufactured to the exact material and dimensional specification of the original hardware installed at the factory. Verified fitment covers the P33/24 FR/FC/FCR, P33/24 HHMR-BD with Blade, RW1403HF, RW1404, RW1404MR (including serial number 326075 and up), and RW1504HF up to serial number. Stocking genuine OEM hardware like the 58329 ensures fastener assemblies on your roller maintain their designed clamping force and resistance to loosening under vibration.
Key Features
- Genuine OEM Hardness and Temper — Manufactured to the original material specification, ensuring the washer delivers the correct spring tension and bite under torque rather than deforming or flattening like inferior hardware.
- Direct Drop-In Hardware Fit — Sized at 14mm to seat flush on the same fastener positions as the original, with no rework, reaming, or modification to surrounding hardware needed.
- Broad RAMMAX and P33/24 Roller Coverage — Confirmed fitment for RW1403HF, RW1404, RW1404MR, RW1504HF, and P33/24 FR/FC/FCR and HHMR-BD with Blade variants.
- Vibration Resistance — Lock washers are specifically chosen for applications subject to continuous vibration; using the correct OEM part maintains fastener preload so critical assemblies do not back off during compaction operations.
- Serial Number Variant Coverage — Fitment is confirmed for RW1404MR serial number 326075 and up and RW1504HF up to serial number 1534188, so you can order with confidence for your specific machine build.
A lock washer is a deceptively simple but functionally critical fastener component. Its job is to maintain clamping force on a bolted joint by biting into both the fastener and the mating surface, preventing the bolt or nut from backing off due to vibration, thermal cycling, or dynamic loading. On walk-behind rollers like the RW1404 and P33/24 series — machines that transmit constant vibration through their frames during compaction — inadequately secured fastener joints can lead to component loosening, misalignment, or hardware loss. Replacing worn, flattened, or missing lock washers with the correct OEM 58329 part restores the joint integrity the machine was designed to operate with.
