Multiquip 3237 Screw HHFS 3/8-16 x 1.25 Zinc

The Multiquip 3237 is a genuine OEM Screw HHFS 3/8-16 x 1.25 Zinc designed for a wide range of Multiquip and Whiteman equipment including MD105 hydrostatic ride-on trowels, HHN34TVD and HHXD5 mechanical ride-on trowels, WRS5200 and WRSPUDF ride-on roller screeds, and DAC7000SS series super-silent generators. As a genuine OEM fastener, this screw is manufactured to the exact dimensions and zinc finish specified for these machines. Verify your model code against the fitment list to ensure this is the correct hardware for your application. DHS Equipment supplies this part direct, backed by Multiquip OEM sourcing.

Key Features

• Genuine OEM Zinc-Plated Fastener — Manufactured to Multiquip's exact thread specification (3/8-16) and length (1.25 in.), with a zinc coating that resists corrosion in outdoor and high-moisture jobsite environments.
• Correct Thread Engagement — The hex head flange design distributes clamping load evenly without a separate washer, seating flush against mating surfaces as intended in the original assembly.
• Broad Cross-Family Fitment — Confirmed for MD105, HHXDF4-DF5, HHNG5, HHXD5, HHN34TVD ride-on trowels, WRS5200, WRS5200DFPU, WRSPUDF roller screeds, and DAC7000SS, DAC7000SSA, DAC7000SSW generators.
• Structural Integrity at the Connection Point — A correctly torqued, properly dimensioned screw maintains secure panel, guard, and component attachment. A stripped or undersized substitute fastener can allow panels to loosen under vibration, leading to rattling, misalignment, or component damage.
• Safety-Relevant Hardware — On ride-on trowels and roller screeds, fasteners securing guards, frames, and drive assemblies are directly tied to operator safety. Using the specified OEM screw ensures retention strength meets the original design requirement.

A hex head flange screw combines a standard hex bolt head with an integrated flanged washer base, eliminating the need for a separate flat washer while providing a wider bearing surface that resists pull-through and distributes load across the joint. The 3/8-16 thread designation indicates a coarse-thread fastener well suited to steel structural connections that require confident grip and repeatable torque under vibration. The zinc plating on part 3237 provides a sacrificial barrier against rust, which is especially important on equipment that operates outdoors, contacts wet concrete, or is stored in variable conditions. When a fastener fails — whether through corrosion, thread damage, or incorrect substitution — it can allow attached components to shift or detach, compromising both machine function and operator safety.
