The Multiquip ST4125D0611 Bolt M6X16L is a genuine OEM fastener designed for the ST6125D and ST4125D clean water submersible pumps. This is the exact factory hardware specified for these units, ensuring correct thread engagement, torque retention, and a secure fit in the original mounting positions. Multiquip OEM status means this bolt matches the original material grade, thread pitch, and head dimensions used during production. Confirm compatibility against your ST6125D or ST4125D serial plate before ordering.
Key Features
- Genuine OEM Hardware Grade — Manufactured to the exact material specification of the original fastener, maintaining correct clamping force and corrosion resistance in wet submersible environments.
- Direct Drop-In Replacement — M6x16L thread and head dimensions match the original mounting points on ST6125D and ST4125D assemblies, installing without modification to the existing hardware positions.
- Confirmed Fitment — Sourced directly for ST6125D and ST4125D Multiquip clean water submersible pump models.
- Structural Integrity at the Joint — A correctly spec'd fastener maintains consistent clamping load across pump housing panels and covers; an undersized or incorrect bolt risks housing separation and seal failure under operating pressure.
- Wet-Environment Application — Selected for service in submersible pump assemblies where hardware is continuously exposed to water, making material grade and dimensional accuracy critical to long service intervals.
The Bolt M6X16L is a metric fastener used to secure housing panels, covers, or internal assemblies on the ST6125D and ST4125D submersible pumps. Fasteners in submersible applications bear both mechanical loads from vibration and environmental exposure from constant water contact, making exact specification a practical necessity rather than a preference. Using an incorrect or worn bolt risks joint loosening, housing misalignment, or compromised sealing — all of which can affect pump output and internal component protection.
