Multiquip 2187 Screw SHC 5/16-18 x 2-1/2 Gr 5 Pltd

The Multiquip 2187 is a genuine OEM Screw SHC 5/16-18 x 2-1/2 Gr 5 Pltd designed for Whiteman and International ride-on power trowels and roller screeds across multiple series, including STX6H, HTX6H, HTXD6i, HHXG5, LD60, JWN24HTCSL, WRS5200, and related models. Sourced directly from Multiquip, this fastener is manufactured to the same specification as the original hardware installed at the factory. Verified fitment across STX, HTX, HHX, LD, JWN, and WRS series equipment means you can order with confidence that part number 2187 is the correct replacement for your machine.

Key Features

• Grade 5 Plated Construction — Medium-carbon steel with a protective plated finish delivers the shear and tensile strength required in high-vibration trowel and screed applications.
• Socket Head Cap (SHC) Drive Design — The hex socket drive allows torque to be applied cleanly in tight or recessed mounting locations common on ride-on trowel frames and screed assemblies.
• Genuine OEM Multiquip Hardware — Part number 2187 is an authentic Multiquip component, ensuring correct thread pitch (5/16-18 UNC), grip length, and plating grade match the original specification.
• Broad Series Compatibility — Fits STX, HTX, HHX, LD, JWN, and WRS series machines, making it a practical stock item for fleets running multiple Whiteman and International ride-on units.
• Drop-In Replacement — Identical dimensions to the original fastener allow direct installation without thread chasing, re-drilling, or adapting surrounding hardware.

A socket head cap screw is a precision fastener used to clamp and secure structural and mechanical components on ride-on power trowels and roller screeds. The socket drive profile concentrates clamping force evenly, making it well suited to the constant vibration these machines produce during concrete finishing. When a fastener of this type loosens, backs out, or fails, it can allow critical assemblies to shift or detach, affecting both machine performance and operator safety — making timely replacement with the correct OEM part essential.
