The Multiquip 021110120 Lock Nut M10 is a genuine OEM fastener designed for a wide range of Multiquip rollers and rammers, including AR13, RW1404, RW1504, RW1403, RW3010, MTR40HF, MT-E55, and MT60H2 series equipment. As a direct OEM replacement, this lock nut is manufactured to the exact thread specification and torque retention requirements of the original hardware. Sourcing the correct OEM fastener ensures a secure, lasting connection — critical in high-vibration applications where an undersized or incorrect nut can back off under load. DHS Equipment supplies this part direct, so you can confirm fitment by part number 021110120 before you order.
Key Features
- OEM Thread and Torque Specification — Manufactured to the exact M10 thread pitch and prevailing-torque rating specified for these machines, ensuring the nut holds under sustained vibration without backing off.
- Direct Hardware Replacement — Replaces the original lock nut using existing fastener positions with no rework to mounting hardware or mating components.
- Broad Multiquip Fitment — Compatible with AR13D, AR13H, AR13HA/HAR, AR13HC, RW1403HF, RW1404, RW1404MR, RW1504HF, RW3010, MTR40HF, MT-E55, and MT60H2 models.
- Vibration-Resistant Locking Design — The prevailing-torque locking feature resists self-loosening in the high-cycle vibration environments typical of compaction rollers and rammers.
- Critical Fastener Integrity — A failed or missing lock nut can allow structural and drivetrain components to shift or separate; using the correct OEM specification part maintains safe, predictable machine behavior.
A lock nut is a fastener engineered to resist loosening under vibration and dynamic loading. Unlike a standard nut, it incorporates a prevailing-torque feature — such as a nylon insert or distorted thread — that creates resistance against rotation even when subjected to repeated shock and vibration cycles. In compaction rollers and rammers, virtually every fastened joint is exposed to constant vibration, making the use of correctly specified lock nuts essential to maintaining structural integrity. When a lock nut fails or is substituted with an incorrect grade or thread pitch, the clamped joint can loosen progressively, leading to component misalignment, accelerated wear, or sudden mechanical failure.
