The Multiquip 022531412 is a genuine OEM Lock Nut U-M14 P=1.5 MRX-440P designed for the MRX-440P walk-behind roller. As a direct Multiquip OEM part, 022531412 is manufactured to the exact thread specification — M14 with a 1.5mm pitch — ensuring a correct, secure fit with no guesswork on compatibility. This fastener is a purpose-matched replacement for the MRX-440P, keeping critical assemblies properly torqued and secured during operation. DHS Equipment supplies this part direct from Multiquip's authorized parts network, so you can be confident you're getting the right component for your machine.
Key Features
- OEM Thread Precision — Manufactured to an exact M14 x 1.5mm pitch specification, matching the original fastener standard used on the MRX-440P to eliminate the risk of cross-threading or improper engagement.
- U-Type Locking Design — The U-style lock nut profile resists loosening under vibration and load cycles, which is critical on a walk-behind roller that generates continuous compaction force during use.
- Direct Fitment for MRX-440P — Sourced specifically for the Multiquip MRX-440P walk-behind roller; installs as a like-for-like replacement with no modification to surrounding hardware.
- Genuine Multiquip OEM Part — Produced under Multiquip's OEM quality standards, ensuring the correct material grade and dimensional tolerances for a fastener that holds under sustained operational stress.
- Critical Retention Function — A failed or missing lock nut on a roller can allow assemblies to shift or detach under load; replacing with the correct OEM part restores proper component retention and operational integrity.
A lock nut is a prevailing-torque fastener designed to resist loosening caused by vibration, shock, and dynamic loading — conditions that are constant on a walk-behind vibratory roller like the MRX-440P. The U-type profile on this nut provides a secondary locking mechanism beyond standard thread friction, holding critical components firmly in place through repeated compaction passes. When a lock nut strips, cracks, or goes missing, the assembly it secures can shift or separate, creating both a mechanical failure risk and a safety concern — making timely replacement with the correct OEM part essential.
