Multiquip 0107090650 Bolt 3/8-24UNFX50 (Impeller)

The Multiquip 0107090650 is a genuine OEM Bolt 3/8-24UNFX50 (Impeller) designed for QP4TH and QP4TZ series quick-prime trash pumps. As a direct Multiquip OEM part, it is manufactured to the exact thread specification and dimensional tolerances required by the original design, ensuring a secure and correctly torqued impeller installation. This bolt is a critical fastener in the pump assembly, and using the correct OEM part eliminates the risk of thread mismatch or fastener failure under demanding pumping conditions. Confirm your model against QP4TH and QP4TZ before ordering to ensure an accurate fit.

Key Features

• Exact Thread Specification: — Machined to 3/8-24 UNF fine-thread standard, matching the original impeller fastener spec for correct engagement and torque retention.
• Genuine OEM Part: — Sourced directly from Multiquip, this bolt meets the same material grade and dimensional standard as the bolt installed at the factory.
• Confirmed Fitment: — Validated for QP4TH and QP4TZ quick-prime trash pump models; verify your model code before ordering.
• Impeller Retention Integrity: — A correctly spec'd impeller bolt keeps the impeller locked at the proper position on the shaft, maintaining pump flow rate and preventing wobble or cavitation caused by a loose or incorrect fastener.
• Fastener Safety in High-Load Applications: — Trash pump impellers operate under significant rotational force; using an undersized or mismatched bolt risks fastener shear, impeller separation, and potential pump housing damage.

The impeller bolt secures the impeller directly to the pump shaft, holding it in precise alignment so the pump can move water and entrained solids efficiently through the volute. If this bolt is loose, worn, or of an incorrect thread pitch, the impeller can shift on the shaft, causing vibration, reduced flow, and accelerated wear on surrounding components. Replacing a damaged or missing impeller bolt with the correct OEM fastener restores the mechanical integrity of the pump assembly and prevents costly secondary damage to the shaft or housing.
