The Multiquip 13339-001 is a genuine OEM External Shakeproof Washer 5/16 designed for Multiquip light towers and Whiteman ride-on power trowels. This washer is a direct OEM replacement sourced to match the original hardware specification, ensuring a correct and secure installation on LT6K, MLT25DCA, HTN27K, and HTN28K equipment. Keeping the right hardware on hand means less time chasing down fastener failures and more time keeping your equipment in service.
Key Features
- Genuine OEM Hardware Grade — Manufactured to the same external shakeproof profile as the original, delivering the locking retention expected for vibration-prone assemblies on light towers and power trowels.
- Drop-In 5/16 Fit — Sized to the 5/16 fastener spec used across multiple Multiquip assemblies, seating correctly against mating surfaces without adjustment or rework.
- Broad Multiquip Fitment — Confirmed for LT6K and MLT25DCA towable light towers as well as HTN27K and HTN28K Whiteman ride-on power trowels.
- Vibration Resistance — The external shakeproof tooth pattern bites into the bearing surface to resist loosening under the constant vibration these machines generate during operation.
- Critical Fastener Integrity — A worn or missing shakeproof washer allows fasteners to back out under load, which can compromise structural connections and create unsafe operating conditions on trowels and tower masts.
An external shakeproof washer works by using serrated outer teeth that dig into the surface of the material being fastened, creating mechanical resistance that prevents a nut or bolt from loosening under vibration or dynamic load. On equipment like light towers and ride-on power trowels, where engines, rotating blades, and mast assemblies generate constant movement, this type of hardware is essential to maintaining fastener clamp force. When a shakeproof washer wears flat or goes missing, the corresponding fastener becomes vulnerable to backing out, which can lead to loose assemblies, accelerated wear on surrounding components, or unsafe equipment operation.
