The Multiquip 20988 Screw FHSC Phillips 8-32 X 1-1/4 is a genuine OEM fastener designed for Whiteman and Multiquip walk-behind power trowel series including B46, J36, JA, CA, BA, and HDA models. As a direct OEM replacement, part 20988 matches the original specification for thread pitch, head profile, and length — ensuring a secure, rattle-free installation without modification. This screw is also compatible with SCT36 and SCT46 saw models, as well as HPLA, HPHA, and M30 series trowels, making it a widely used hardware component across the Multiquip portfolio. Keeping the correct fastener on hand is a straightforward way to complete panel, guard, or housing reassembly correctly the first time.
Key Features
- Genuine OEM Thread Spec: — Manufactured to the exact 8-32 thread standard and 1-1/4 inch length specified for original assemblies, ensuring full thread engagement without stripping.
- Flat-Head Phillips Profile: — The FHSC (flat-head socket cap / countersunk Phillips) head seats flush with mounting surfaces, preventing interference with guards, panels, and housings during reassembly.
- Broad Cross-Series Compatibility: — Fits B46, J36, JA, CA, BA, HDA, HPLA, HPHA, M30 walk-behind trowel series, plus SCT36 and SCT46 saw models — one part number covering a wide range of Multiquip equipment.
- Correct Clamping Load: — Using the OEM-specified fastener maintains the designed clamping force on covers and structural panels, preventing loosening under the continuous vibration loads that walk-behind trowels generate.
- Direct-from-Multiquip Sourcing: — Supplied as a genuine Multiquip OEM component, so the head markings, plating, and material grade match what left the factory originally.
A flat-head countersunk Phillips machine screw like the Multiquip 20988 is used to fasten panels, guards, covers, and structural brackets throughout walk-behind trowel and saw assemblies. Its countersunk profile allows the head to sit flush or below the surface, which is critical on moving equipment where a proud fastener head could snag operators or interfere with adjacent components. When the wrong thread pitch, length, or head style is used as a substitute, fasteners can back out under vibration, strip the receiving thread, or create misalignment in the assembled panel — leading to guard failures or time-consuming teardowns to correct the issue.
