The Multiquip 50422500 is a genuine OEM Counter Sunk Screw M6X12 designed for QP2TZ and QP3TZ series trash pumps. Sourced directly from Multiquip, this fastener meets the exact material grade and dimensional specification required for proper installation on these machines. If you are servicing a QP2TZ or QP3TZ and need a correctly sized M6X12 counter sunk screw, part 50422500 is the confirmed OEM fitment. Having the right fastener on hand keeps your pump assembly properly secured and ready to return to service.
Key Features
- Correct Thread and Head Profile: — M6X12 counter sunk specification ensures flush seating and full thread engagement in the intended boss or panel, preventing fastener backing-out under pump vibration.
- Genuine OEM Material Grade: — Manufactured to Multiquip's original hardness and corrosion-resistance standards for fasteners used in wet, high-vibration pump environments.
- Drop-In Installation: — Counter sunk head geometry matches the existing countersink in the mating component, so no drilling, reaming, or modification to the pump housing is needed.
- Confirmed QP2TZ and QP3TZ Fitment: — Verified OEM replacement for both Multiquip quick-prime trash pump models in the QP2TZ and QP3TZ families.
- Structural Integrity Under Load: — A loose or incorrect fastener in a trash pump assembly can allow covers or internal components to shift, leading to misalignment or premature seal wear; the correct screw holds everything firmly in spec.
A counter sunk screw is a flush-mount fastener designed so its tapered head sits level with or below the surface of the mating component when fully driven. In trash pump assemblies, these screws are commonly used to secure covers, wear plates, and housing panels where a protruding fastener head could interfere with moving parts or impede serviceability. When a counter sunk screw is stripped, corroded, or missing, the affected panel can shift under vibration, compromising the pump's structural integrity and potentially allowing debris ingestion or fluid leakage. Replacing it with the correct OEM screw — the right thread pitch, length, and head angle — restores the assembly to its original secure condition.
