Multiquip 2549 HHCS 1/2-13 x 3

The Multiquip 2549 HHCS 1/2-13 x 3 is a genuine OEM hex head cap screw built for a wide range of Multiquip and Whiteman equipment including ride-on trowels, roller screeds, masonry saws, flat saws, and mortar mixers. As a direct OEM fastener, it meets the exact thread specification, length, and grade required by the original engineering. Confirmed fitment includes HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, STX55J6, STX55Y6, STXD6i, HHN31V, HHN34TVD, WRS5200, WRS5200DFPU, WRSPUDF, WM45H, MP2050E1, MP2050E3, MP2090HP, SP118, SP1CE13H18, SP1G, SP2S20H, EM120SM, WSHE-A Series, and additional models. Sourcing the correct fastener by part number ensures structural integrity across assemblies where torque and clamping load are critical.

Key Features

• Genuine OEM Thread Specification — Manufactured to the exact 1/2-13 UNC thread standard and 3-inch length specified in Multiquip's original engineering documentation, ensuring correct clamping force across all listed assemblies.
• Drop-In Fastener Replacement — Installs directly into existing threaded holes and mating hardware without modification, maintaining the original bolt pattern and torque requirements of the assembly.
• Broad Cross-Equipment Fitment — A single part number covering ride-on trowels (HTX44, STX55, HHN series), roller screeds (WRS5200, WRSPUDF), masonry and flat saws (MP series, SP series), mortar mixers (WM45H), and vibratory screeds (WSHE-A Series).
• Structural Integrity Where It Counts — Using the correct grade and dimensional spec prevents fastener stretch, thread galling, and joint loosening under the vibration and load cycles these machines generate during operation.
• Fastener-Grade Reliability for Critical Joints — An undersized, incorrect, or worn fastener in a structural application can lead to component misalignment or failure; sourcing by OEM part number eliminates that risk.

A hex head cap screw is a fully threaded or partially threaded fastener used to clamp structural and mechanical components together within an assembly. The 1/2-13 designation refers to the nominal diameter and thread pitch, while the 3-inch length determines the grip range and engagement depth for the specific joint it secures. In high-vibration equipment such as compaction machines, power trowels, and screeds, fasteners are subject to continuous dynamic loading — using a fastener that matches the original specification in grade, thread form, and length is essential to maintaining joint preload and preventing loosening or fatigue failure over time.
