Multiquip 10087 Nyloc Nut 1/2-20 Thin

The Multiquip 10087 Nyloc Nut 1/2-20 Thin is a genuine OEM fastener designed for Whiteman and International ride-on power trowel models including HHN31V, HHN34TVD, JWN24HTCSL, HHNG5, and EHHNK5. As a direct OEM replacement, part 10087 matches the original thread pitch, diameter, and nylon locking insert specification to ensure a secure, vibration-resistant installation. DHS Equipment stocks this part to keep your trowel running with zero guesswork on fitment. Verify your model code against the list below before ordering to confirm compatibility.

Key Features

• Vibration-Locking Nylon Insert — The nylon collar grips threads under load, preventing self-loosening on high-vibration ride-on trowel applications where fastener backing-off causes operational issues.
• Correct 1/2-20 Thread Specification — Fine-thread 1/2-20 pitch matches the OEM fastener spec exactly, threading directly onto existing hardware without rework or thread chasing.
• Genuine OEM Part — Sourced directly from Multiquip, this nut meets the same material grade and dimensional tolerances as the original hardware installed at the factory.
• Thin Profile Design — The reduced-height profile fits in tight or low-clearance mounting locations common on Whiteman ride-on trowel assemblies where a standard-height nut will not seat properly.
• Broad Trowel Family Coverage — Fits HHN31V, HHN34TVD, JWN24HTCSL, HHNG5, and EHHNK5 ride-on power trowels, covering both Whiteman domestic and International series machines.

A nyloc nut is a standard hex nut fitted with a nylon locking insert at the top of the nut body. When threaded onto a bolt or stud, the nylon collar deforms slightly around the threads, creating friction that resists loosening caused by vibration, torque cycling, and dynamic loads. On ride-on power trowels, where rotating blade assemblies and drive components generate continuous vibration, maintaining correct fastener torque is critical — a backed-off or missing nut can lead to component movement, accelerated wear on mating parts, or loss of blade control. The thin profile of the Multiquip 10087 makes it suited to confined fastening locations where a full-height nyloc nut would interfere with adjacent hardware.
