A Vulcan Hart 00-498567-00001 Lock Nut with External Tooth Washer keeps threaded components firmly in place to maintain a stable assembly during use.
The lock nut with external tooth washer secures threaded connections in grill and griddle assemblies so mounted components stay tight and correctly aligned during operation. Its hex body allows reliable tightening, while the integrated external tooth washer increases grip against vibration and movement that could otherwise loosen the fastener over time.
The lock nut with external tooth washer might need replacement if equipment components begin to loosen, shift out of position or produce vibration-related rattling during use. Common indicators include worn threads, reduced locking tension, corrosion from heat or cleaning exposure or visible washer tooth damage that can compromise fastening security.
