A Vulcan Hart NS-031-20 Lock Washer with Nylon Insert keeps threaded connections from loosening so the assembly stays secure during routine use.
The lock washer with nylon insert secures threaded connections in dicer, cutter and chopper assemblies so components stay properly fastened during operation and vibration. Its hex form and nylon insert improve grip and resistance to loosening, which matters for maintaining alignment, stability and dependable equipment performance.
The lock washer with nylon insert may need replacement if fastened parts start to loosen, shift or require frequent retightening during normal equipment use. Common indicators include visible wear on the hex body or threads and environmental signs may include heat exposure, moisture or cleaning chemicals that could degrade the nylon insert over time.
