The Multiquip 0191170625 Bolt Set with Lock Washer is a genuine OEM fastener set designed for QP3TK, QP3TB, and QP3TH series pumps. As a direct Multiquip OEM component, it is manufactured to the same specifications as the hardware originally installed at the factory, ensuring a correct and secure fit every time. This set is verified to fit QP3TK trash pumps, the QP3TB centrifugal pump, and the QP3TH trash pump, making it a reliable choice when servicing equipment across these pump families. When sourcing fastener hardware, using the correct OEM bolt set keeps critical assemblies properly torqued and secured for safe, consistent operation.
Key Features
- Genuine OEM Hardware Grade — Manufactured to Multiquip's original specifications, ensuring correct thread pitch, bolt diameter, and lock washer tension for pump assembly applications.
- Complete Fastener Set — Includes matching lock washers, so bolts and washers are paired correctly for a full hardware replacement in a single order.
- Confirmed Pump Fitment — Verified for QP3TK, QP3TB, and QP3TH models, covering both trash and centrifugal pump configurations in this series.
- Secure Clamping Integrity — Lock washers resist loosening under vibration, maintaining proper clamp load on pump housings, covers, and mounting points during continuous operation.
- Direct Service Replacement — Replaces worn, stripped, or corroded original fasteners with hardware that seats and torques the same way as the factory-installed set.
A bolt set with lock washer is a critical fastener assembly used to secure pump housings, end covers, and internal components together under operating load. The lock washers apply spring tension against the bolt head to prevent the fastener from backing out due to vibration — a common failure point on pump equipment that runs continuously or on rough terrain. When fasteners are stripped, corroded, or missing their lock washers, pump assemblies can shift, leak, or lose structural integrity, leading to premature wear or operational failure.
