The Multiquip ZT130A9 is a genuine OEM Split Lock Washer Medium 1/4 designed for the BP-25H gasoline backpack flex-shaft vibrator. As a factory-sourced component, it meets the exact material and dimensional requirements specified for this machine, ensuring correct clamp load and thread security throughout service. This washer is a direct-fit replacement that installs without any modification to the existing fastener assembly on BP-25H units. DHS Equipment stocks this part to help you keep your concrete vibrator running without extended delays waiting on critical hardware.
Key Features
- Genuine OEM Hardware Grade — Sourced directly from Multiquip, this split lock washer meets the precise hardness and spring-tension spec required to maintain secure fastener torque on vibrating equipment.
- Direct-Fit 1/4" Sizing — Sized to match the 1/4" fastener locations on the BP-25H, this washer seats and locks exactly as the original, with no filing, shimming, or adaptation needed.
- Confirmed Fitment for BP-25H — Verified compatible with the BP-25H gasoline backpack flex-shaft vibrator, so you can order with confidence knowing this is the correct part for your machine.
- Vibration-Resistant Locking Action — The split-ring design bites into both the fastener face and the mating surface under load, resisting the constant vibration that backpack vibrators generate during concrete consolidation work.
- Critical Fastener Integrity — A worn or missing split lock washer allows fasteners to back out under vibration, which can lead to loose assemblies, component misalignment, and accelerated wear on surrounding parts.
A split lock washer is a hardened, open-ring fastener component that sits between a bolt head or nut and the mating surface. Its split ends act as a spring, maintaining tension on the fastener even when the assembly is subjected to continuous vibration. On backpack concrete vibrators like the BP-25H, where the entire machine transmits high-frequency vibration through its frame and shaft, split lock washers play a quiet but essential role in keeping every bolted connection tight. When a split lock washer loses its tension, flattens, or is missing entirely, fasteners can work loose over time, causing rattles, component shift, and potential damage to the flex-shaft drive or housing components.
