The Multiquip EM400283 Hex Nut M6 is a genuine OEM fastener designed for QP3TZ and QP2TZ series trash pumps. Sourced directly from Multiquip, this hex nut meets the exact thread specification and material grade used in original production, ensuring a secure, correctly torqued connection every time. Whether you are replacing a damaged or missing fastener during routine service or a field repair, the EM400283 is the correct OEM-specified part for these machines. Confirmed fitment covers the QP3TZ and QP2TZ Hatz-powered trash pump models.
Key Features
- OEM-Matched Thread Specification — Manufactured to the exact M6 thread pitch and grade used at the factory, so the nut seats and torques correctly without risk of cross-threading or fastener failure.
- Direct-Fit Replacement — Drops straight into the existing fastener position on QP3TZ and QP2TZ trash pumps with no modification to hardware or mating components.
- Confirmed Fitment — Verified OEM fitment for QP3TZ and QP2TZ Hatz-powered trash pump models.
- Structural Integrity Under Load — A properly rated hex nut maintains clamping force on pump housings and covers during high-vibration operation; an undersized or incorrect fastener can back out and allow component shift or fluid leakage.
- Fuel and Fluid System Safety — Where used in pump housing or cover assemblies, a correctly specified fastener prevents loosening that could expose rotating parts or compromise sealed enclosures during operation.
A hex nut is a threaded fastener used to clamp and secure two or more components together when paired with a bolt or stud. On trash pumps like the QP3TZ and QP2TZ, hex nuts are used throughout the pump housing, engine mounting, and cover assemblies to maintain structural integrity under continuous vibration and load. When a hex nut is stripped, corroded, or missing, the joint it secures can loosen over time, leading to misalignment, leaks, or component damage that goes well beyond the cost of the fastener itself.
