The Multiquip 2866 is a genuine OEM Hex Head Cap Screw M8-1.25 x 20 MM designed for a broad range of Multiquip and Whiteman equipment, including Water Trailer models, STX55Y6, STX55J6, HTX44K4, HTX44K5, HTN27K, HTN28K, HHN31V, HHN34TVD, HHXD5, HHXD5-ES, HHXDF4-DF5, and HHXG5. As a genuine OEM component, part 2866 is produced to the exact material grade and thread specification called out in the original Multiquip build documentation. Sourcing the correct fastener by part number matters on this equipment — an incorrect thread pitch or head dimension can compromise joint clamping force and lead to panel or structural hardware failure in the field.
Key Features
- Correct Thread Specification: — M8-1.25 x 20 MM thread form matches the tapped holes on covered assemblies exactly, ensuring full thread engagement and proper clamp load.
- Genuine OEM Material Grade: — Manufactured to the same tensile and hardness specification as the original fastener, so joint integrity is maintained across the service life of the equipment.
- Hex Head Cap Drive: — Standard hex head profile accepts common wrench and socket sizes for straightforward installation or removal during routine service.
- Broad Cross-Equipment Fitment: — A single part number covers Water Trailer series (WT5C, WTE5C), Whiteman hydrostatic ride-on trowels (STX55, HTX44), and Whiteman mechanical ride-on trowels (HTN, HHN, HHX), consolidating your parts inventory.
- Structural Reliability: — Using a fastener of the correct grade and length prevents loosening under vibration loads typical of ride-on trowels and water trailers operating on uneven surfaces.
A hex head cap screw is a fully threaded or partially threaded fastener used to clamp two or more components together at a specified torque. In ride-on trowels and water trailer assemblies, these screws secure panels, guards, frame brackets, and mechanical sub-assemblies where consistent clamping force under vibration is critical. When the wrong thread pitch is used, the screw may cross-thread or fail to develop full clamp load; when the wrong length is used, the screw may bottom out before clamping or extend beyond the joint and foul adjacent components. Replacing a worn or damaged fastener with the correct Multiquip 2866 restores the joint to its original specification and prevents progressive loosening during operation.
