The Multiquip ST4125D0221 Bolt M12XM20L is a genuine OEM fastener designed for ST6125D and ST4125D series submersible clean water pumps. As an original equipment component, it is manufactured to the exact dimensional and material specifications required for proper assembly and secure retention within the pump. This bolt is a direct OEM replacement, making it the correct choice when servicing or rebuilding your Multiquip submersible pump and restoring it to original operating condition.
Key Features
- Genuine OEM Material Grade — Manufactured to the exact tensile strength and thread specification required for secure fastening in submersible pump assemblies, where vibration and moisture exposure demand consistent holding force.
- Exact M12XM20L Thread Dimensions — Matches the precise thread pitch, diameter, and length of the original bolt, seating flush and torquing correctly without rework or shimming.
- Confirmed Fitment for ST6125D and ST4125D — Verified OEM application for Multiquip ST6125D and ST4125D submersible clean water pump models.
- Structural Integrity Under Continuous Operation — A correctly spec'd fastener maintains critical joint clamping force during pump operation; an incorrect or worn bolt can lead to loosening, misalignment, or housing leaks.
- Sourced Direct from Multiquip — Supplied as a genuine Multiquip part, ensuring part number ST4125D0221 matches your equipment's original build specification.
This bolt serves as a structural fastener within the Multiquip submersible pump assembly, securing key components of the pump housing or internal mechanism under continuous wet-environment operating conditions. Fasteners in submersible applications must maintain consistent clamping force against vibration and fluid pressure — a fastener that is the wrong length, thread pitch, or material grade can compromise the seal or structural integrity of the assembly. Replacing a worn or damaged bolt with the correct OEM part ensures the pump holds together as designed and continues to move clean water efficiently.
