The Multiquip 21024 Lock Washer 1/4 is a genuine OEM component designed for WTB-16 and WTB-16PD power buggies. Sourced directly from Multiquip, this fastener hardware is built to the same specification as the original, ensuring a proper seat and holding force at every fastened joint. It is a verified direct replacement for WTB-16 and WTB-16PD machines, so installation drops straight into the existing fastener stack without any modification. Keeping the correct hardware in place is essential for structural integrity on a power buggy that moves heavy concrete loads across an active jobsite.
Key Features
- Genuine OEM Fastener Spec — Manufactured to Multiquip's exact material grade and dimensional tolerances for the 1/4 inch lock washer position, maintaining the correct clamp load at each fastened joint.
- Direct Hardware Match — Replaces the original 21024 lock washer in the existing fastener stack; seats flush against mating surfaces the same way the factory-installed washer does.
- Confirmed Fitment — Compatible with WTB-16 and WTB-16PD Whiteman track power buggies.
- Prevents Fastener Loosening — The locking profile bites into the fastener and mating surface under load, resisting vibration-induced loosening that is common in power buggy operation over rough terrain.
- Structural Safety — Correct fastener hardware is critical on load-bearing and drive-system connections; using the specified lock washer maintains joint integrity when transporting heavy concrete loads.
A lock washer is a hardened fastener insert placed between a nut or bolt head and the mating surface to prevent the fastener from backing out under vibration or dynamic loading. On a power buggy like the WTB-16 series, continuous movement over uneven ground and the torque forces of the drive system create constant vibration at every bolted joint. When a lock washer wears flat, loses its spring, or is omitted, fasteners can work loose over time, leading to play in critical components, accelerated wear, and potential structural failure under a full load.
