Multiquip 0105051240 Casing Bolt M12X40

The Multiquip 0105051240 is a genuine OEM Casing Bolt M12X40 designed for QP402H and QP402B centrifugal pumps. As a direct OEM replacement, this bolt is manufactured to the same specifications as the original hardware, ensuring a secure, properly torqued casing joint every time. Verified compatible with QP402H and QP402B pump models, this is the correct fastener to reach for when servicing or reassembling the pump casing. Sourced direct from Multiquip, part number 0105051240 ships as an authorized OEM component.

Key Features

• OEM-Grade Fastener Material — Manufactured to the same metallurgical grade and thread specification as the original bolt, delivering the clamping force the pump casing joint requires.
• Correct M12X40 Thread and Length — The M12X40 sizing ensures the bolt seats flush through the casing flanges without bottoming out or under-engaging the threaded bore.
• Confirmed Fitment for QP402 Series — Verified for QP402H and QP402B centrifugal pumps, so you can order with confidence for these specific models.
• Maintains Casing Integrity Under Pressure — A correctly specified casing bolt keeps pump housing halves sealed under operating pressure, preventing leaks and maintaining priming efficiency.
• Genuine Multiquip OEM Part — Sourced directly through the Multiquip OEM supply chain, ensuring part number 0105051240 matches the original design intent exactly.

The casing bolt on a centrifugal pump is a critical structural fastener that clamps the pump housing sections together, maintaining a leak-free seal around the impeller chamber. When these bolts are damaged, corroded, or improperly torqued, the casing joint can weep or fail under pressure, causing loss of prime, reduced flow output, and potential pump damage. Replacing a worn or stripped casing bolt with the correct OEM-spec fastener restores the housing seal and keeps the pump operating at full capacity.
