The Multiquip EM963055 is a genuine OEM 3/8 NC x 3/4 G5 Bolt designed for a wide range of Multiquip equipment including MC-series concrete mixers, LS-series concrete pumps, AR-series ride-on rollers, WBH-series power buggies, PRO-series stationary mixers, and R2000H static rollers. As a factory-sourced fastener, it meets the original torque and material specifications required for proper assembly across all compatible units. Verified fitment includes models such as MC94P/S, MC64P/S, MC44S, MC12PH, LS300GK, LS300, LS300G, LS300P, LS600P, AR13H, AR13HA/HAR, AR13HC, AR13D, R2000H, WBH-16, WBH-16E, WBH-16EF, WBH-16F, WBH-16EAWD, WBH-16EAWDF, WBH-21EF, WBH-21EFP, PRO12, PRO12E51, PRO12E53, and PRO20. Sourcing OEM hardware ensures correct grade and thread spec so structural connections hold under load and vibration.
Key Features
- Grade 5 Tensile Strength — Manufactured to G5 specification, providing the minimum tensile and proof-load ratings required for structural and mechanical fastening on Multiquip equipment.
- Correct Thread Form for Direct Installation — 3/8 NC (National Coarse) thread form matches factory-tapped holes and standard nuts used throughout the compatible equipment range — no chasing or re-tapping needed.
- Broad Cross-Family Fitment — A single OEM part number covering MC-series mixers, LS-series concrete pumps, AR-series and R2000H rollers, WBH-series power buggies, and PRO-series stationary mixers.
- Vibration-Resistant Clamping — Proper grade and length ensure consistent clamp load on joints that are exposed to continuous vibration during compaction, mixing, and pumping cycles.
- Genuine OEM Sourcing — Supplied directly from Multiquip's authorized parts catalog, meaning the alloy composition, head dimensions, and thread tolerances match the original hardware specified at the factory.
A Grade 5 hex bolt is a structural fastener used to clamp two or more components together with a defined amount of clamping force determined by its tensile rating and torque specification. On construction equipment like concrete mixers, pumps, rollers, and power buggies, these bolts secure panels, frames, drive components, and ancillary assemblies that are subject to constant vibration and mechanical stress. When a bolt of the wrong grade or thread pitch is substituted, it can loosen prematurely, strip the receiving threads, or fail under load — compromising both machine integrity and operator safety. Using the correct OEM-specified fastener maintains joint integrity and prevents costly damage to surrounding hardware.
