The Multiquip ST4125D0201 is a genuine OEM Bolt M12x40L designed for the ST4125D and ST6125D submersible clean water pumps. As a direct OEM replacement, it meets the original assembly specifications set for these pumps, ensuring a correct, secure fit wherever this fastener is used in the unit. This bolt is a stocked replacement at DHS Equipment, sourced directly through Multiquip's authorized parts channel to guarantee authenticity. If you're servicing or reassembling an ST4125D or ST6125D, using the correct OEM hardware eliminates the guesswork of sourcing a compatible substitute.
Key Features
- Genuine OEM Hardware Grade — Manufactured to the exact M12x40L thread specification used in original pump assembly, not a generic hardware substitute.
- Correct Thread and Length Match — The M12 thread diameter and 40mm length are specific to this assembly position, ensuring full thread engagement and proper torque retention.
- Confirmed Fitment for ST4125D and ST6125D — Verified for use on Multiquip ST4125D and ST6125D submersible clean water pump models.
- Maintains Pump Structural Integrity — A correctly torqued, properly sized fastener keeps pump housing components aligned and sealed under operating load — an undersized or incorrect bolt can lead to loosening, misalignment, or housing damage.
- Direct OEM Source — Supplied through Multiquip's authorized parts network, so the part number, grade, and specification are exactly what left the factory.
A bolt like the ST4125D0201 plays a straightforward but critical role in keeping a submersible pump's components clamped together securely during operation. On a submersible pump, fasteners are exposed to constant vibration, water pressure, and thermal cycling, all of which can cause an incorrect or worn bolt to loosen over time. Using the correct OEM fastener with the right thread pitch, diameter, and length ensures the joint holds at the designed clamping force, protecting the pump's internal components and housing seals from the effects of movement or misalignment.
