Multiquip 90003Z6L800 Hex Bolt 3/8-16 UNC

The Multiquip 90003Z6L800 is a genuine OEM Hex Bolt 3/8-16 UNC designed for the AR14H asphalt ride-on roller. Sourced directly from Multiquip, this fastener matches the exact thread specification — 3/8-16 UNC — required for proper installation on AR14H series machines. As a genuine OEM component, it is built to the same standards as the hardware installed at the factory, ensuring correct torque performance and fit within the assembly. Confirm 90003Z6L800 against your parts manual before ordering to ensure this is the correct fastener for your application.

Key Features

• Exact Thread Specification: — 3/8-16 UNC thread profile matches the OEM fastener requirement, ensuring proper thread engagement without reworking the receiving component.
• Genuine OEM Hardware: — Produced to Multiquip's original material and dimensional standards, so tensile strength and corrosion resistance are consistent with the original bolt.
• Direct Replacement for AR14H: — Confirmed fitment for the AR14H asphalt ride-on roller; drops in where the original fastener is removed.
• Structural Integrity: — A correctly spec'd hex bolt keeps critical assemblies properly clamped and torqued. A stripped, incorrect, or fatigued fastener can lead to component loosening under the vibration loads common in roller operation.
• Hex Drive for Standard Tooling: — Standard hex-head format works with common socket and wrench sets used on the jobsite, making installation and future service straightforward.

A hex bolt is a fundamental structural fastener that clamps two or more components together by applying clamping force when torqued to specification. On a ride-on roller like the AR14H, fasteners across the frame, drivetrain, and drum assemblies are subject to constant vibration and load cycling, making the correct grade and thread specification critical. Using an undersized, incorrect-thread, or worn fastener in these positions can allow components to shift or separate, compromising both machine function and operator safety.
