The Multiquip 021118220 is a genuine OEM Nylon Nut M18 MRX-440P designed for the MRX-440P walk-behind roller. As a factory-sourced component, it meets the exact material grade and thread specification required for proper installation on this machine. Sourced directly through authorized Multiquip supply channels, this nut is the correct replacement when the original hardware shows wear, stripping, or damage. Confirm your model is the MRX-440P before ordering to ensure a direct match.
Key Features
- Nylon Insert Locking Design — The nylon collar grips the mating thread under vibration, resisting loosening during continuous roller operation where hardware can back out over time.
- Correct M18 Thread Specification — Sized and threaded to the M18 standard used in the original assembly, allowing straightforward installation with no thread chasing or modification to the fastener boss.
- Genuine OEM Component — Manufactured to Multiquip's material and torque-retention standards for the MRX-440P, not a generic hardware substitute.
- Direct MRX-440P Fitment — Engineered specifically for the MRX-440P walk-behind roller; part number 021118220 maps directly to this machine's bill of materials.
- Structural Integrity Under Load — A properly torqued, undamaged nylon lock nut keeps critical fastened joints secure, preventing component shift or separation that can affect roller alignment and operator control.
A nylon lock nut uses an integrated nylon insert to create friction against the bolt thread once fully seated, preventing the nut from backing off due to vibration or cyclic loading. On a walk-behind roller like the MRX-440P, exposed hardware is subject to constant vibration, and a nut that loosens or strips can allow structural or mechanical components to shift out of position. Replacing worn or damaged hardware with the correct OEM-specified nut — part number 021118220 — restores the clamping integrity of the joint and keeps the assembly performing as designed.
