The Multiquip EM505081 Hex Nut 7/16 is a genuine OEM fastener designed for use across multiple Multiquip equipment families, including R2000H and AR14H rollers and LS300P, LS300G, and LS300GK concrete pumps. Sourced directly from Multiquip, this hex nut is manufactured to the exact dimensions and material specifications required for correct clamping force and thread engagement in these applications. Keeping the correct fastener on hand helps ensure critical assemblies stay properly secured during demanding jobsite operation.
Key Features
- OEM-Grade Fastener Material — Manufactured to Multiquip's exact hardness and thread specification, ensuring proper torque load and thread engagement without stripping or deformation.
- Direct-Fit Replacement — The 7/16 sizing matches the original fastener configuration, threading directly onto existing hardware without reworking mating components.
- Broad Multiquip Compatibility — Fits R2000H static rollers, AR14H asphalt ride-on rollers, and LS300P, LS300G, and LS300GK hydraulic concrete pumps.
- Structural Integrity Under Load — A correctly torqued hex nut maintains clamping force on assembled components; an incorrect or worn fastener can allow loosening under vibration and operational stress.
- Genuine Multiquip OEM Part — Sold under part number EM505081, this is an authentic replacement backed by Multiquip's OEM supply chain.
A hex nut is a threaded fastener used to clamp and secure components together when paired with a bolt or threaded stud. In construction equipment, fasteners like the EM505081 Hex Nut 7/16 are critical to keeping structural, mechanical, and housing assemblies properly joined under continuous vibration and load. When a hex nut is missing, stripped, or the wrong specification, it can allow assembled parts to shift or loosen, leading to accelerated wear on mating components or potential failure of the assembly it secures.
