Made from stainless steel, this 1\/4 inch washer provides corrosion resistance in wet, outdoor, and chemically active environments. The split ring design bites into the bearing surface and fastener head to maintain clamp load over time. Each box contains 100 washers, making it a practical stocking item for service vehicles or shop inventory. Plumbers, electricians, HVAC technicians, and general contractors regularly rely on stainless lock washers where galvanic compatibility and rust resistance are required.\u003c\/p\u003e\n\u003cp\u003eThese washers are suited for 1\/4 inch fastener applications across residential and light commercial work. Common install scenarios include pipe hanger assemblies, electrical panel mounting, equipment brackets, and outdoor structural connections where standard zinc or plain steel hardware would corrode. The stainless steel construction makes them a direct fit wherever code or spec calls for corrosion-resistant hardware. Sold in a 100-piece pack, they are well-suited for bulk restocking on service trucks or in supply rooms.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMedium split lock washer design resists fastener back-out under vibration\u003c\/li\u003e\n  \u003cli\u003eStainless steel construction offers corrosion and rust resistance\u003c\/li\u003e\n  \u003cli\u003eSized for 1\/4 inch fasteners\u003c\/li\u003e\n  \u003cli\u003e100 washers per pack for efficient restocking\u003c\/li\u003e\n  \u003cli\u003eSuitable for wet, outdoor, and corrosive service environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard medium split lock washer for 1\/4 inch fasteners used in general trade, HVAC, plumbing, and electrical installation applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall lock washers between the fastener head or nut and the bearing surface before final torque.
