Multiquip 10 Lock Nut 3/8-16

The Multiquip 10 is a genuine OEM Lock Nut 3/8-16 designed for a wide range of Multiquip, Whiteman, and Essick equipment across multiple product families. This fastener is a direct OEM replacement sourced to exact Multiquip specifications, covering plate compactors such as the MVC70E and MVC70EW, ride-on trowels including HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, STX55Y6, and STX55J6, walk-behind trowels across the B Series, J Series, and C Series platforms, rammers including the MT60H2 and MT85, rollers, mixers, pumps, screeds, generators, power buggies, and more. With fitment spanning this many equipment families, verifying your model against part number 10 before ordering is always recommended.

Key Features

• Genuine OEM Fastener Grade — manufactured to Multiquip's specified thread class and torque rating for 3/8-16 fastener applications, ensuring the locking mechanism holds under operational vibration and load.
• Direct Drop-In Replacement — threads directly onto any 3/8-16 stud or bolt position where this lock nut is called out in the Multiquip parts diagram, requiring only standard hand tools to install.
• Broad Cross-Family Fitment — confirmed for use across plate compactors (MVC70E, MVC70EW), ride-on trowels (HTX44K4, HTX44Y4, STX55Y6), walk-behind trowels (B Series, J Series, C Series), rammers (MT60H2, MT85), rollers, mixers, pumps, and additional Multiquip product lines.
• Vibration Resistance — the locking feature is critical on compaction, troweling, and screed equipment where continuous vibration can back standard nuts off fastener positions over time, leading to component loosening or structural failure.
• Critical Safety Fastener — lock nuts used in blade, guard, and structural attachment points on trowels and compaction equipment directly affect operator safety; using the correct OEM-specified nut maintains the integrity of those connections.

A lock nut is a nut engineered with an internal locking feature — typically a nylon insert or a deformed thread — that resists loosening caused by vibration, shock loads, or dynamic movement. On construction equipment like trowels, compactors, rammers, and rollers, mechanical vibration is constant, and standard nuts can gradually back off their fastener positions if not properly locked. The Multiquip 10 Lock Nut 3/8-16 is used at specific fastener points throughout the machine where that self-loosening risk is present. When a lock nut fails or is replaced with an incorrect fastener, connected components can shift, wear prematurely, or detach — creating both mechanical damage and potential safety hazards for the operator.
