Multiquip 5070 Lock Nut 3/4-10

The Multiquip 5070 is a genuine OEM Lock Nut 3/4-10 designed for a wide range of Multiquip equipment including MVC and MVH series plate compactors, MT series rammers, MRH series walk-behind rollers, and MLT and LT light towers. As a factory-sourced fastener, part 5070 meets the exact thread specification and material standard required for proper torque retention across all compatible assemblies. This lock nut ships directly from authorized Multiquip inventory, so you can verify fitment with confidence before installation. Confirmed compatible models include MVC88VTH, MVC88VTHW, MVCE64V, MVCe82VBW, MVCi60, MVH308DE, MVH308DZ, MVH308GH, MVH408DE, MVH408DZ, MVH408GH, MVH508DE, MVH508DZ, MVH508GH, MVH508GV, MT60H2, MT85, MTR40HF, MRH601DS, MRH800GS, LT6K, MLT25DCA, and EM120SM.

Key Features

• Genuine OEM Thread Integrity — Sourced directly from Multiquip, this 3/4-10 lock nut holds the exact thread pitch and locking torque spec required for safety-critical fastening on compaction and lifting assemblies.
• Drop-In Replacement — Matches the original 3/4-10 thread standard for a direct swap with no recutting, chasing, or hardware substitution needed at the point of installation.
• Broad Cross-Family Fitment — A single part number covers MVC and MVH plate compactors, MT and MTR rammers, MRH walk-behind rollers, MLT and LT light towers, and Essick EM120SM mixers.
• Locking Retention Under Vibration — The lock nut design resists backing off under the sustained vibration loads generated by compaction equipment and roller drives, maintaining clamp force over extended operation cycles.
• Fastener-Grade Material Compliance — Built to the material and hardness requirements of the original hardware specification, ensuring the nut does not strip, gall, or deform under rated torque application.

A lock nut differs from a standard hex nut in that it incorporates a locking feature — typically a nylon insert or a prevailing-torque thread form — that resists loosening when the fastener is subjected to vibration, shock loads, or thermal cycling. On compaction equipment like plate compactors and rammers, fasteners are exposed to continuous high-frequency vibration that would cause a standard nut to back off over time, leading to loose assemblies, accelerated wear on mating components, or structural failure at the joint. Using the correct OEM-specified lock nut, such as Multiquip part 5070 with its 3/4-10 thread size, ensures the joint holds its clamping load through the full service interval and that torque values remain predictable during routine inspection and maintenance.
