The Multiquip 5277 is a genuine OEM HHC Screw 1/4-20 x 1-1/2 designed for a wide range of Multiquip and Whiteman power trowels, ride-on screeds, and masonry saws. As a factory-sourced fastener, part 5277 is manufactured to the exact thread pitch, head geometry, and material grade specified for these machines. Verified fitment includes walk-behind trowels such as the CA4HM and CA-4-4H, ride-on trowels including the STX55Y6, STX55J6, HTX44Y4, HTX44Y5, HTX44K4, HTX44K5, HHN34TVD, HHN31V, HHNG5, HTN28K, HTN27K, HTN-KHOLER/ONAN/HONDA, and HTNS5S-2, as well as ride-on roller screeds WRS5200, WRSPUDF, and WRS5200DFPU, masonry saws MP2090HP, MP2050E3, MP2050E1, MP2H, MP275E3, MP25E3, MP25E1, MP1455HP, MP120E, MP115E, and MP1H, and wheel kit WKTHD. Sourcing the correct OEM fastener eliminates the guesswork around thread compatibility and torque performance on precision-assembled equipment.
Key Features
- OEM Thread Accuracy — Manufactured to the exact 1/4-20 thread specification required by Multiquip, ensuring full thread engagement and proper clamping load on every installation.
- Hex Head Cap Profile — The HHC head style allows standard socket or wrench access, making installation and removal straightforward during service or reassembly.
- Broad Verified Fitment — Confirmed for Multiquip and Whiteman walk-behind trowels, ride-on trowels (STX55, HTX44, HHN, HTN series), ride-on roller screeds (WRS series), and Multiquip masonry saws (MP series).
- Structural Integrity Where It Counts — Used across guard, panel, and frame attachment points on trowels and screeds; an incorrect or worn fastener at these locations can lead to component loosening under vibration during operation.
- Genuine OEM Sourcing — Supplied direct from Multiquip's parts chain, so the grade, finish, and dimensional tolerances match the original hardware your machine left the factory with.
A hex head cap screw is a fully threaded or partially threaded fastener with a six-sided head, designed to be driven by a wrench or socket for controlled torque application. On equipment like power trowels and ride-on screeds, fasteners such as the 5277 secure panels, guards, and structural components that are subject to constant vibration during operation. When a fastener is the wrong thread pitch, incorrect length, or has degraded from wear or corrosion, it can fail to maintain proper clamping force — allowing joined components to shift, loosen, or separate during use. Replacing worn or damaged hardware with the correct OEM specification fastener restores the mechanical integrity of the assembly.
