Product Description

This is a genuine Husqvarna replacement part. Lock nuts are often used in the assembly of lawn and garden equipment because they resist loosening. Lawn mowers, snow blowers, lawn tractors, tillers, and trimmers can produce a high amount of vibration during operation, lock nuts work to keep everything in place while you are operating your machinery. Uses and applications vary depending on equipment type, which is why we recommend you refer to model specific diagrams. This replacement part is sold individually.
