Multiquip 0131290689 Cap Screw Casing Cover Set Bolt

The Multiquip 0131290689 Cap Screw Casing Cover Set Bolt is a genuine OEM fastener designed for QP3THX and QP3TS series trash pumps. As an OEM part, it is manufactured to the exact specifications required for a correct, secure fit on the pump casing cover. This bolt is confirmed compatible with QP3THX and QP3TS models, giving you confidence that you are ordering the right hardware the first time. DHS Equipment supplies this part direct, so you can get your pump back in service without guesswork.

Key Features

• Genuine OEM Fastener Integrity — Manufactured to exact thread pitch, shank diameter, and head dimensions specified for the casing cover assembly, ensuring the bolt seats and torques correctly every time.
• Secure Casing Cover Retention — Engineered to hold the pump casing cover under operating pressure and vibration, maintaining the sealed integrity of the pump housing.
• Confirmed Fitment for QP3THX and QP3TS — Verified for use on Multiquip QP3THX and QP3TS trash pumps, so you can cross-reference part number 0131290689 with confidence.
• Corrosion-Resistant Hardware Grade — Built to withstand the wet, debris-laden environments typical of trash pump operation, where fastener corrosion or thread failure leads to casing leaks and pump downtime.
• Direct OEM Replacement — Drops into the existing casing cover bolt pattern with no rework, fitting the same holes and thread receivers as the original hardware.

The casing cover set bolt is a critical fastener that clamps the pump casing cover firmly against the pump housing, maintaining a pressure-tight seal around the volute and impeller chamber. Without properly torqued, undamaged set bolts, the casing cover can shift or leak under load, allowing air ingestion that disrupts prime and reduces flow output. Replacing worn, stripped, or corroded bolts like the 0131290689 as part of routine pump servicing helps keep the casing assembly sealed and the pump performing at full capacity.
