The split lock design provides tension under a fastener head or nut, resisting loosening caused by vibration and torque relaxation. The washer measures 0.22 inches minimum inside diameter, up to 0.227 inches maximum inside diameter, with a maximum outside diameter of 0.377 inches and a thickness of 0.056 inches. This box contains 100 washers, making it suitable for production assembly, maintenance kits, or service-truck stock. Electricians, HVAC technicians, plumbers, and general trade contractors use split lock washers daily in panel, equipment, and structural fastening applications.\u003c\/p\u003e\u003cp\u003eThis washer is sized for Number 12 screws in inch-measurement fastening systems. It is appropriate for light to medium-duty mechanical assemblies where vibration resistance is required and a military-specification washer is not called out. Common applications include electrical enclosure assembly, HVAC unit cabinet fastening, sheet-metal work, and equipment mounting where a standard inch-series Number 12 fastener is specified. The yellow zinc dichromate finish provides basic corrosion resistance suitable for indoor and mildly protected outdoor environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSplit lock design resists fastener loosening under vibration and dynamic loads\u003c\/li\u003e\n\u003cli\u003eGrade 2 spring steel construction provides reliable tension retention\u003c\/li\u003e\n\u003cli\u003eYellow zinc dichromate finish offers corrosion resistance for general service environments\u003c\/li\u003e\n\u003cli\u003eSized for Number 12 inch-series screws with 0.22 inch inside diameter\u003c\/li\u003e\n\u003cli\u003eSold in a box of 100 for job-site and bench-stock use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Number 12 inch-series screws and fasteners in standard inch-measurement assemblies.

Ensure the washer seats flat against both mating surfaces before driving the fastener. Power down or de-energize any equipment before servicing fastened assemblies in electrical or HVAC applications.
