Multiquip 2186 SHC Screw 5/16-18 x 2-1/4 PLTD

The Multiquip 2186 SHC Screw 5/16-18 x 2-1/4 PLTD is a genuine OEM fastener designed for HTX, STX, HHN, HTN, LD, JWN, and WRS series equipment. As a direct OEM replacement, part 2186 meets the exact thread specification, length, and plated finish required by Multiquip for these applications. Verified fitment covers a wide range of Whiteman ride-on power trowels and roller screeds, including models HTX6H, LD60, LD6/LD6SL, HHXG5, HHXD5, STXDF. Sourcing the correct OEM fastener by part number ensures proper clamp load and thread engagement, keeping critical assemblies secure through demanding concrete finishing cycles.

Key Features

• Genuine OEM Thread Specification — Manufactured to the exact 5/16-18 thread form and 2-1/4 inch length called out in Multiquip service documentation, ensuring correct torque values are achieved without thread damage.
• Plated Finish for Corrosion Resistance — The electroplated surface provides a protective barrier against moisture and jobsite contaminants, extending the service life of the fastener in outdoor and wet concrete environments.
• Socket Head Cap (SHC) Drive Design — The hex socket drive allows high-torque installation in tight or recessed locations using a standard Allen key or hex bit, reducing the risk of cam-out during assembly.
• Broad Series Fitment — Confirmed for HTX, STX, HHN, HTN, LD, JWN, and WRS series machines, making this a practical stock item for fleets running multiple Whiteman ride-on trowel and roller screed models.
• Maintains Structural Integrity of Critical Assemblies — Using the specified fastener preserves proper clamp load across blade, deck, and frame connections; substituting an incorrect length or grade can allow joint movement that accelerates wear on surrounding components.

A socket head cap screw is a precision fastener used to clamp two or more components together with a controlled, repeatable torque. In ride-on trowels and roller screeds, fasteners like the Multiquip 2186 secure blade arms, guard panels, frame brackets, and drive components where access space is limited and a flush or recessed head profile is required. When a fastener stretches, corrodes, or is replaced with an incorrect size, the resulting loss of clamping force can allow micro-movement between mated parts, accelerating wear on mounting surfaces and eventually leading to component failure or unsafe operating conditions.
