Multiquip EM98163 Hex Head Bolt

The Multiquip EM98163 is a genuine OEM Hex Head Bolt designed for use across a wide range of Multiquip, Whiteman, Essick, and Mayco equipment. This fastener is sourced directly through Multiquip's OEM parts program, ensuring correct thread spec, grade, and dimensional fit for every application it covers. Compatible models span multiple equipment families including rollers (V305EK, V305EH, V303E, R2000H), concrete pumps (LS300GK), Mayco concrete pumps (C30HDGA, C30HDG, C30HDN, C30HDZ, C30HDNI, C30HDNI Precision, C30HDNI Zenith), Essick stationary mixers (PRO12, PRO12E51, PRO12E53), Whiteman mortar mixers (WM120SH, WM120PH), Essick mixers (EM120S Series, EM120P Series, EM70P/S, EM90P/S), and additional equipment including vibratory screeds and trash pumps. Using the correct OEM fastener on critical joints protects the structural integrity of the assembly and avoids the risk of mismatched hardware causing joint failure.

Key Features

• Correct Thread Grade and Dimensional Spec — Manufactured to OEM tolerances, ensuring the bolt engages threads fully and clamps at the rated torque value for each application.
• Genuine OEM Part — Sourced through Multiquip's authorized parts program, this bolt carries the same specification as the hardware installed at the factory across all covered equipment families.
• Broad Cross-Equipment Compatibility — A single part number serves rollers, concrete pumps, stationary mixers, mortar mixers, trash pumps, and vibratory screeds including V305EK, LS300GK, PRO12, WM120SH, R2000H, and C30HD-series machines.
• Structural Joint Integrity — A correctly spec'd hex head bolt maintains the clamping force required to keep housings, guards, and structural members seated under operational vibration and load.
• Drop-In Hardware Replacement — Matches the original head size, shank diameter, thread pitch, and length, so no chasing threads or sourcing alternate hardware is needed during service.

A hex head bolt is a threaded fastener used to clamp two or more components together, typically torqued with a wrench to a specified value that creates the clamping force holding the joint. On heavy construction equipment, fasteners like the EM98163 are used throughout frames, housings, guard panels, and mechanical assemblies where vibration, load cycles, and environmental exposure put constant stress on the joint. When a bolt is the wrong grade, incorrect length, or has a mismatched thread pitch, the joint can loosen prematurely, strip the mating threads, or fail to reach the required clamp load — leading to component movement, accelerated wear on adjacent parts, or structural failure during operation.
