The Multiquip 0181090820 is a genuine OEM Bolt Set with Lock Washer designed for QP-series trash pumps and centrifugal pumps including QP2TK, QP2TH, QP2TB, QP3TB, QP3TK, QP3TS, QP3THX, QP3TH, QP2TZ, QP3TZ, QPT305SLT, QP305SLT, QPT205SLT, and QP205SLT. As a factory-sourced component, this set delivers the correct thread spec, bolt grade, and lock washer pairing that Multiquip engineered into these pump models from day one. Whether you are performing routine maintenance or reassembling a pump after a seal or impeller service, having the right hardware on hand keeps the job moving. DHS Equipment stocks this part as an authorized Multiquip OEM supplier, so you can order with confidence knowing you are getting the exact replacement.
Key Features
- Correct Thread Grade and Torque Rating — OEM bolt grade ensures proper clamping load at pump housing joints, preventing loosening under vibration and fluid pressure.
- Matched Lock Washer Included — The lock washer is paired to the bolt diameter at the factory, eliminating mismatched hardware and ensuring consistent seating against pump covers and flanges.
- Broad QP-Series Compatibility — Fits QP2TK, QP2TH, QP2TB, QP2TZ, QP3TB, QP3TK, QP3TS, QP3THX, QP3TH, QP3TZ, QPT305SLT, QP305SLT, QPT205SLT, and QP205SLT models.
- Direct Drop-In Hardware — Replaces the OEM bolt set position for position, with no rework of mounting holes or additional hardware required during reinstallation.
- Genuine Multiquip OEM Part — Sourced directly from Multiquip, part 0181090820 meets the same material and dimensional standards as the hardware installed at the factory on trash pump and centrifugal pump models.
A bolt set with lock washer serves as the primary fastening hardware that secures pump housings, covers, and flanged connections on QP-series pumps. The bolts clamp mating surfaces together under load, while the lock washers resist the rotational loosening that constant engine vibration and pressure cycling would otherwise cause over time. When these fasteners are worn, stretched, or replaced with incorrect hardware, pump covers can develop leaks, and critical sealing surfaces may shift under pressure — leading to performance loss or fluid bypass. Using the correct OEM-specification bolt set ensures every joint is clamped to the designed load and stays secure through continuous operation.
