Multiquip 73431100301 Hex Screw M10

The Multiquip 73431100301 Hex Screw M10 is a genuine OEM fastener designed for ST41230, ST41460, ST61230, and ST61460 submersible pumps. As a factory-sourced component, this screw is manufactured to the exact thread pitch, head geometry, and material grade specified for these units, ensuring a correct and secure fit every time. Keeping critical fasteners at spec is essential on submersible pump assemblies where vibration and continuous operation place constant stress on hardware.

Key Features

• OEM-Grade Fastener Material — Manufactured to the same thread pitch, tensile strength, and corrosion-resistance spec as the original hardware used in Multiquip submersible pump assembly.
• Direct Drop-In Replacement — M10 hex configuration matches the existing bolt pattern and drive spec on these pump models, so installation requires no modification to mounting surfaces or surrounding hardware.
• Confirmed Fitment — Verified for ST41230, ST41460, ST61230, and ST61460 submersible pump models.
• Maintains Structural Integrity Under Load — Submersible pumps operate in demanding, submerged conditions; a correctly torqued, properly spec'd fastener helps prevent housing loosening, leaks, and premature seal failure.
• Genuine Multiquip OEM Part — Sourced directly from Multiquip, so the part number, thread spec, and dimensions match exactly what was installed at the factory — no guesswork on fitment.

A hex screw in a submersible pump assembly serves as the primary fastener holding housing panels, end caps, motor brackets, or impeller covers securely together. In a submerged environment, even slight fastener loosening can compromise the sealed enclosure, allowing water ingress that damages the motor or disrupts pump output. A worn, stripped, or incorrect-spec screw can lead to housing separation, vibration-related fatigue on adjacent components, or complete pump failure — making correct hardware replacement just as important as replacing any wear part.
