The Multiquip 50423900 is a genuine OEM Countersunk Screw M6X20 designed for Multiquip trash pump and heavy-duty reversible plate compactor models including QP3TZ, QP2TZ, MVH408DZ, and MVH308DZ. As a factory-sourced fastener, it meets the exact thread pitch, head geometry, and material grade specified by Multiquip for these machines. Sourcing the correct OEM screw ensures panels, covers, and structural components seat flush and torque to spec without stripping or misalignment. Verify your model against the confirmed fitment list before ordering to ensure a direct match.
Key Features
- OEM-Grade Fastener Material — Manufactured to Multiquip's specified hardness and corrosion-resistance rating, ensuring the screw holds clamping load through repeated vibration cycles on compactors and pumps alike.
- M6X20 Countersunk Profile — The flush-seating countersunk head allows covers and panels to sit flat against mating surfaces, eliminating proud fastener heads that can catch, vibrate loose, or interfere with adjacent components.
- Confirmed Fitment Across Two Equipment Families — Directly compatible with QP3TZ and QP2TZ trash pumps and MVH408DZ and MVH308DZ heavy-duty reversible plate compactors.
- Drop-In Replacement — Matches the original thread specification exactly, threading into existing bosses and tapped holes without re-tapping or modification to the host component.
- Protects Structural Integrity — A failed or incorrect fastener on a high-vibration machine can cause cover panels to loosen and internal components to shift; using the correct OEM screw maintains the assembled integrity of the unit under load.
A countersunk screw is a threaded fastener with a conical head designed to sit flush with — or below — the surface of the material it secures. On equipment like plate compactors and trash pumps, countersunk fasteners are used where a protruding fastener head would interfere with operation, expose a snag point, or prevent proper seating of a mating panel or guard. When this screw wears, strips, or is replaced with an incorrect substitute, the secured component can shift under vibration, leading to accelerated wear on surrounding parts or loss of a protective cover during operation. Using the correct M6X20 part ensures the joint remains tight and the assembly functions as designed.
