The Multiquip EM128 is a genuine OEM Bolt, 5/8" Dia designed for AR13D asphalt rollers, C30HD series concrete pumps, and V303E vibratory rollers. As a direct OEM replacement, the EM128 is manufactured to the same specifications as the original hardware, ensuring correct torque loading and structural integrity at every installation point. Sourced directly through authorized Multiquip channels, this bolt is a straightforward drop-in replacement for compatible models including the AR13D, C30HDGA, C30HDZ, C30HDG, C30HDNI, C30HDN, C30HD, and V303E. DHS Equipment stocks genuine Multiquip parts so you can get the right component and get your machine back to work without guesswork.
Key Features
- Genuine OEM Hardware Grade — Manufactured to the exact material and thread specification of the original bolt, ensuring correct clamping force and resistance to shear stress under operating loads.
- 5/8" Diameter Fit — Correct diameter and thread pitch for direct installation into OEM-spec mounting points with no rework or re-tapping required.
- Broad Model Compatibility — Fits AR13D asphalt rollers, V303E vibratory rollers, and the full C30HD concrete pump family including C30HDGA, C30HDZ, C30HDG, C30HDN, C30HDNI, and C30HD variants.
- Structural Integrity Maintained — Using the correct OEM bolt grade prevents under-torque failures and joint loosening that can lead to component misalignment or accelerated wear on adjacent parts.
- Verified Multiquip Part Number — Carries the genuine Multiquip part number EM128, eliminating the risk of receiving a mismatched or undersized fastener from a generic supplier.
A bolt of this diameter serves as a primary structural fastener in assemblies where consistent clamping force is critical — such as mounting frames, drive system brackets, and pump housings. When a fastener stretches, corrodes, or is replaced with an incorrect grade, joint integrity is compromised, which can cause vibration-induced loosening, misalignment of connected components, or accelerated wear on surrounding hardware. Using the correct OEM-specification Multiquip EM128 ensures the joint performs as engineered across the full range of operating conditions these machines encounter.
