The Multiquip 503114 is a genuine OEM Hex Head Cap Screw 5/16-18 X 3-1/2 designed for the AR14H asphalt ride-on roller. As a direct Multiquip OEM replacement, 503114 is manufactured to the same specification as the original hardware installed at the factory, so you can trust the thread pitch, grip length, and material grade are correct for the application. This screw is confirmed for use on AR14H series equipment and ships as a single fastener ready for immediate installation. Sourcing the correct OEM hardware eliminates the guesswork that comes with substituting generic fasteners in critical assembly positions.
Key Features
- Correct Thread and Length Specification — 5/16-18 UNC thread with a 3-1/2 inch grip length matches the original fastener specification exactly, so the screw seats and clamps as intended without rework.
- Genuine OEM Hardware — Sourced directly through Multiquip, this fastener meets the same material and tensile requirements as the screw originally installed on your machine — no guessing at equivalents.
- Confirmed AR14H Fitment — Verified for the Multiquip AR14H asphalt ride-on roller; always cross-reference part number 503114 against your machine's serial plate and parts manual before ordering.
- Structural Integrity Where It Counts — Using the correct grade and dimension of fastener in roller assemblies maintains proper clamping force and prevents loosening under the vibration loads typical of compaction work.
- Direct Drop-In Replacement — Installs in the same position as the original with standard hand tools, requiring no thread chasing, bushing, or adapter hardware.
A hex head cap screw is a fully threaded or partially threaded fastener used to clamp two or more components together in a bolted joint. In ride-on roller assemblies, fasteners like this one are used throughout the frame, drive system, and auxiliary component mounts, where consistent clamping load is essential to safe and stable machine operation. When a fastener stretches, corrodes, or is replaced with an incorrect substitute, joint integrity is compromised — leading to looseness, vibration damage, or component failure over time.
