The Multiquip 1278 is a genuine OEM PHP 8-32 x 3/8 Screw designed for Whiteman and International ride-on power trowels including the HTN28K, HTN27K, HTN-KHOLER/ONAN/HONDA, HTNS5S-2, and HHXDF4-DF5. As a factory-sourced component, it meets the exact thread specification and head geometry required for correct installation and secure seating on these machines. Sourced directly through the Multiquip OEM supply chain, part 1278 delivers the fit and integrity you need to keep your trowel operating as built. DHS Equipment stocks this part and stands ready to help you verify compatibility before you order.
Key Features
- Correct Thread Form and Drive Type — PHP (Pan Head Phillips) profile with an 8-32 thread pitch and 3/8-inch length matches the original fastener spec exactly, ensuring proper clamping force without stripping or under-torquing.
- Genuine OEM Sourcing — Manufactured to Multiquip's original material and dimensional standards, so the screw engages mating threads the same way the factory-installed hardware does.
- Broad Ride-On Trowel Fitment — Confirmed for HTN28K, HTN27K, HTN-KHOLER/ONAN/HONDA, HTNS5S-2, and HHXDF4-DF5 ride-on power trowel models.
- Structural Integrity Under Vibration — Ride-on trowels generate sustained vibration during finishing passes; a correctly specified fastener maintains its clamped joint and prevents loosening that could affect panel alignment or guard retention.
- Simple Drop-In Replacement — Standard 8-32 Phillips drive means no special tooling is required; the screw seats and torques with common hand tools already on the job.
A PHP 8-32 x 3/8 screw is a pan-head, Phillips-drive machine screw used to fasten panels, guards, brackets, or electrical covers on ride-on power trowels. The 8-32 designation refers to the thread diameter and pitch, while the 3/8-inch length determines how deeply the fastener engages the mating thread or nut. On equipment that operates under continuous vibration, using the correct size and grade of fastener matters — an undersized or mismatched screw can work loose during operation, leading to rattling components, misaligned covers, or exposed wiring. Replacing a worn or missing screw with the genuine Multiquip 1278 restores the assembly to its original clamped condition.
