The Multiquip 3278 is a genuine OEM Screw FHSM 1/4-20 X 1-1/4 designed for HTX and STX series ride-on power trowels, including the HTX6H, HTXG6DF, HTXD6i, STXD6i, and STX6H. As a factory-sourced fastener, part 3278 meets the exact thread spec and head geometry called out in the original Multiquip assembly. Sourcing the correct OEM fastener ensures proper torque retention and flush seating without the risk of cross-threading or dimensional mismatch that can come with generic hardware substitutes.
Key Features
- Genuine OEM Thread Spec: — Factory-sourced 1/4-20 thread form and 1-1/4 inch length match the original torque and clamping requirements of the trowel assembly.
- Flat Head Socket Machine Profile: — FHSM head geometry seats flush with mating surfaces, maintaining a clean, low-profile installation where clearance is critical.
- Confirmed Fitment: — Direct replacement for HTX6H, HTXG6DF, HTXD6i, STXD6i, and STX6H ride-on power trowels.
- Consistent Holding Strength: — Correct thread engagement preserves the clamping load the original design depends on, preventing loosening under the vibration loads typical of ride-on trowel operation.
- Single-Part Availability: — Sold individually so you can replace only what is damaged or lost without purchasing a full hardware kit.
A flat head socket machine screw functions as a structural fastener that draws two components together and sits flush within a countersunk hole, eliminating any protrusion that could interfere with adjacent parts or moving assemblies. On a ride-on power trowel, fasteners like the 3278 are used throughout the frame, guard, and drive system attachments where maintaining precise clamping load is essential to safe and stable operation. A stripped, incorrect, or missing fastener in these locations can allow panels or components to shift under load, leading to accelerated wear on surrounding hardware and potential loss of machine control.
