The Multiquip 4370 is a genuine OEM Screw HHC 3/8"-16 x 2-1/4" designed for a wide range of Multiquip and Whiteman ride-on power trowels, vibratory screeds, and roller screeds. This hex head cap screw is sourced directly from Multiquip, ensuring the correct thread pitch, grade, and dimensional spec for every application it supports. Confirmed fitment includes the STXDF, HHN31V, HHNG5, EHHNK5, HHN34TVD, WSHE-A Series, WRSPUDF, WRS5200, and WRS5200DFPU. Keeping the correct fasteners on hand means no delays when routine service or repairs are due on these machines.
Key Features
- Genuine OEM Grade Fastener — Manufactured to the exact thread specification and material grade called out in the Multiquip parts documentation, so torque values and clamping load behave as designed.
- Correct Thread Engagement — The 3/8"-16 UNC thread form and 2-1/4" length deliver the thread engagement depth the original design requires, with no guesswork on sizing.
- Broad Fitment Across Multiquip Equipment Families — Fits ride-on power trowels including STXDF, HHN31V, HHNG5, EHHNK5, and HHN34TVD, plus WSHE-A Series vibratory screeds and WRSPUDF, WRS5200, and WRS5200DFPU roller screeds.
- Structural Reliability Under Vibration — On trowels and screeds that produce continuous vibration during operation, fasteners are under constant stress; using the specified OEM screw maintains joint integrity over extended run times.
- Direct Drop-In Replacement — Matches the original fastener in every dimension, so it installs without modification into existing threaded holes or hardware assemblies.
A hex head cap screw like the Multiquip 4370 is a structural fastener used to clamp and secure assemblies on power trowels, screeds, and related concrete finishing equipment. On machines that operate under sustained vibration and mechanical load, the thread pitch, shank diameter, and overall length of each fastener are critical to maintaining clamping force across the joint. When the wrong fastener is substituted—or when a screw stretches, strips, or backs out—connected components can shift or loosen, affecting both machine performance and operator safety. Using the correct OEM specification screw ensures the joint holds to its designed clamping load through normal service life.
