The Multiquip ST6125D0221 Bolt M12xM20L is a genuine OEM fastener designed for the ST6125D and ST4125D submersible pump series. This bolt is sourced directly from Multiquip and meets the same specifications as the hardware installed at the factory, ensuring proper torque retention and secure assembly across critical pump components. If you are servicing either the ST6125D or ST4125D and need a direct-fit replacement, this is the correct part.
Key Features
- Genuine OEM Hardware Specification — Manufactured to the exact M12xM20L thread and dimensional spec required by Multiquip, ensuring correct clamping force and thread engagement for submersible pump assemblies.
- Drop-In Service Replacement — Matches the original bolt in thread pitch, length, and head style so it installs directly without modification or fitting adjustments.
- Compatible with ST6125D and ST4125D — Confirmed fitment for both Multiquip clean water submersible pump models in this series.
- Structural Integrity Under Submerged Conditions — A correctly torqued, properly sized bolt maintains pump housing integrity during operation; a worn, stripped, or incorrect fastener risks seal failure and water ingress into motor components.
- Verified Multiquip Part Number — Order with confidence using part number ST6125D0221 to confirm you are receiving the correct OEM fastener for your pump model.
A bolt of this specification secures key structural or component interfaces within the submersible pump assembly — such as the motor housing, impeller casing, or mounting flanges — where consistent clamping load is essential to maintaining watertight seals during submerged operation. If the fastener is missing, damaged, or replaced with an incorrect size, the joint may loosen under vibration or hydraulic pressure, allowing water to compromise the motor or disrupt pump output. Using the correct OEM bolt ensures the assembly stays sealed, properly aligned, and performs as intended over the service life of the pump.
