Husqvarna 503222401 Lock Nut Slotted M5x0.8 8 St Sital BHT

Replacement lock nuts keep your Husqvarna power equipment running when original hardware wears out or gets stripped during blade changes and maintenance work. This slotted lock nut features M5x0.8 threading and comes in a convenient 8-piece pack, giving you enough fasteners to handle multiple repairs or keep spares in your truck. The Sital BHT coating provides corrosion resistance when exposed to concrete dust, water, and jobsite conditions. These OEM parts maintain proper torque specifications and fit tolerances compared to generic hardware store alternatives. Stock these in your toolbox alongside other common wear items to minimize downtime when servicing saws, grinders, and other concrete cutting equipment. Built for equipment operators and maintenance technicians who need factory-spec replacement parts on hand.
