The Multiquip 23305-001 is a genuine OEM Screw HHF M12-1.75 X 30 8.8 Patch designed for a range of Multiquip equipment including ST-45HRM, ST-70, HHXD5, HHXG5, MD82, HHXDF4, and HHXDF5 models. Sourced directly from Multiquip, this fastener meets the exact torque and thread specifications called out in the original equipment design. It installs as a direct drop-in replacement with no rework needed to the mounting location. Confirm your model against the fitment list before ordering to ensure correct application.
Key Features
- Genuine OEM Thread Integrity — M12-1.75 thread pitch and 8.8 grade tensile strength match the original fastener specification exactly, ensuring correct clamp load at the joint.
- Patch-Lock Coating — The factory-applied patch coating provides pre-applied thread locking and resistance to loosening under vibration, which is critical on equipment subject to continuous operational movement.
- Direct-Fit Replacement — At 30mm length with a hex head flange profile, this screw seats flush into the original bore without modification to the mating hardware or mounting surface.
- Broad Multiquip Fitment — Confirmed for use across multiple Multiquip product families including submersible pumps (ST-45HRM, ST-70) and ride-on power trowels (HHXD5, HHXG5, MD82, HHXDF4, HHXDF5).
- Grade 8.8 Structural Rating — The 8.8 property class designation means this screw is engineered for structural fastening applications where joint integrity directly affects equipment operation and safety.
A hex head flange screw like the Multiquip 23305-001 serves as a structural fastener that secures major assemblies and panels, transmitting clamping force evenly across the flange face to prevent joint movement. The M12-1.75 thread profile and 8.8 grade rating mean this fastener is specified for load-bearing connections where an undersized or incorrect fastener could allow critical components to shift or come loose during operation. When a fastener of this type fails — whether through thread stripping, loosening under vibration, or using an incorrect grade — it can lead to misalignment, component damage, or unsafe operating conditions that take a machine out of service entirely.
