Multiquip 1231 Screw HHC 1/2-13 X 2-3/4

The Multiquip 1231 Screw HHC 1/2-13 X 2-3/4 is a genuine OEM fastener used across a wide range of Multiquip and Whiteman equipment, including ride-on trowels, plate compactors, rammers, rollers, mixers, saws, pumps, and generators. As a factory-original component, it is manufactured to the exact dimensional and material specifications required for proper assembly and structural integrity on the machines it serves. Confirmed fitment includes models such as STXDF, HTX6H, PRX, MVH208GH, MTX70HDR, MVC82VHW, WM120SH, and many others across the Multiquip product family. When hardware fails or goes missing, replacing it with the correct OEM part — Multiquip 1231 — ensures the fastened joint performs exactly as designed.

Key Features

• Genuine OEM Specification — Manufactured to Multiquip's exact thread pitch, head dimensions, and grade requirements for this 1/2-13 X 2-3/4 hex head cap screw application.
• Drop-In Hardware Replacement — Matches the original fastener profile and thread engagement length, installing directly without modification to mating hardware or tapped holes.
• Broad Multiquip Fitment — Compatible with ride-on trowels (STXDF, HTX6H, PRX, HTX44K4), plate compactors (MVH208GH, MVC82VHW), rammers (MTX70HDR, MTX60HD), rollers, mixers, saws, pumps, and generators across the Multiquip and Whiteman portfolio.
• Structural Joint Integrity — A correctly torqued, properly sized hex head cap screw maintains clamping load across assembled components; a worn, stripped, or incorrect fastener can allow movement, misalignment, or component separation under load.
• Safety-Critical Fastener — On trowels, compactors, and rotating equipment, fastener failure can result in loose guards, shifting components, or structural separation — using the correct OEM-spec replacement directly supports safe machine operation.

A hex head cap screw (HHC) is a standard threaded fastener used to clamp two or more components together in a bolted joint. The 1/2-13 designation refers to a half-inch nominal diameter with 13 threads per inch (UNC coarse thread), and the 2-3/4 indicates the grip length of the bolt. On equipment like ride-on trowels, plate compactors, and concrete pumps, these fasteners are used throughout the frame, guards, engine mounts, and major assemblies where precise clamping force is essential. When a fastener is lost, stripped, or corroded, substituting an incorrect grade or dimension can compromise joint strength and lead to premature loosening or component damage under vibration and load.
