The Multiquip EM400284 is a genuine OEM Hex Nut M8 designed for a range of Multiquip equipment including the QP3TZ and QP2TZ trash pumps and the RW1404 and P33/24 HHMR-BD rollers. As a genuine OEM component, it is manufactured to the exact thread pitch, hardness, and dimensional tolerances specified by Multiquip for these applications. Sourcing the correct fastener by part number ensures a proper mating fit with the threads and mating surfaces already present on your equipment. DHS Equipment supplies this part direct, so you can order with confidence knowing you are receiving the same component installed at the factory.
Key Features
- Correct Thread Specification: — M8 metric thread profile matches the existing threaded interfaces on covered equipment, eliminating the guesswork of selecting a compatible fastener.
- Genuine OEM Hardness Grade: — Manufactured to the torque and clamping-load specifications required by Multiquip, so critical joints maintain proper clamping force under operating vibration and load.
- Broad Multiquip Fitment: — Confirmed for QP3TZ, QP2TZ, RW1404, and P33/24 HHMR-BD models, covering both the trash pump and roller product families.
- Vibration Resistance: — A correctly spec'd fastener at the right torque prevents joint loosening on high-vibration machines like trash pumps and walk-behind rollers, keeping assemblies secure during continuous operation.
- Drop-In Replacement: — Installs directly into existing threaded bosses and hardware locations with standard M8 tooling — no rethreading or adaptation needed.
A hex nut is a threaded fastener that mates with a bolt or stud to clamp two or more components together. On equipment such as trash pumps and rollers, fasteners are subjected to continuous vibration and mechanical stress, making material grade and thread accuracy critical. Using an undersized, incorrect-grade, or mismatched nut can lead to joint loosening, stripped threads, or fastener failure — potentially causing component separation during operation. Replacing worn or damaged hardware with the correct OEM-specified nut like the EM400284 restores the integrity of the joint and protects the surrounding components from damage.
