As a direct OEM part, it is manufactured to the exact dimensions and grade specifications called out in Multiquip's engineering documentation, ensuring a true like-for-like replacement every time. Sourced directly through an authorized Multiquip parts channel, this bolt ships with full OEM traceability and is backed by the confidence of genuine parts supply.
Key Features
- Certified OEM Grade Fastener — Manufactured to the exact thread pitch, head geometry, and tensile grade specified by Multiquip, so torque values and clamping loads are correct from the first turn.
- Drop-In Installation — Matches the original bolt in every dimension, seating flush into existing mounting points without rework or re-tapping.
- Broad Equipment Compatibility — A single part number covers walk-behind rollers (V305EK, V305EH), ride-on rollers (AR13D), concrete pumps (LS300GK, LS300P, LS600P), power buggies (WTB-16, WBH-21EFP), and Essick stationary mixers (PRO12, PRO12E51, PRO12E53, PRO20).
- Structural Integrity Where It Counts — A correctly spec'd fastener maintains proper joint preload across high-vibration applications; an undersized or incorrect-grade substitute can back out or fail under load, leading to component shifts or machine damage.
- Critical Assembly Compliance — In fuel system, drive, and structural assemblies, using the correct OEM fastener is essential to maintaining safe operating torque specifications — particularly relevant across the pump and roller families this bolt serves.
A hex head bolt is a threaded fastener used to clamp two or more components together, with a six-sided head designed to be driven by a standard wrench or socket. In construction equipment operating under continuous vibration and heavy load cycles — such as concrete pumps, rollers, and power buggies — fasteners are subject to significant stress and can stretch, corrode, or loosen over time. Using the correct OEM-spec replacement ensures the joint holds at its designed clamping force, preventing component movement, structural fatigue, and potential failure in the field.
