The zinc-plated finish provides basic corrosion resistance for general-purpose fastener assemblies in light industrial, mechanical, and trade applications. The washer features a split design that bites into the mating surface and fastener head under torque load, resisting loosening caused by vibration or thermal cycling. Inside diameter ranges from 0.502 to 0.512 inches with a maximum outside diameter of 0.869 inches and a thickness of 0.125 inches. Electricians, HVAC mechanics, plumbers, and general maintenance technicians use these washers wherever standard split lock retention is required.\u003c\/p\u003e\u003cp\u003eThis split lock washer is suited for residential and light commercial mechanical assemblies involving 1\/2-inch fasteners. Common applications include equipment mounting, panel attachment, pipe hanger hardware, and structural bolted connections where vibration resistance is needed. The inch-measurement system and Grade 5 material make it appropriate for standard domestic fastener specifications across multiple trades.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSplit lock design resists fastener back-off under vibration and thermal cycling\u003c\/li\u003e\n\u003cli\u003eGrade 5 steel construction for reliable strength in general-purpose fastener assemblies\u003c\/li\u003e\n\u003cli\u003eZinc-plated finish for basic corrosion resistance\u003c\/li\u003e\n\u003cli\u003eInside diameter 0.502 to 0.512 inches fits standard 1\/2-inch fasteners\u003c\/li\u003e\n\u003cli\u003e0.125-inch thickness provides consistent spring tension under load\u003c\/li\u003e\n\u003cli\u003eInch measurement system compatible with standard domestic hardware\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-fit split lock washer for use with 1\/2-inch screws, bolts, and threaded fasteners in general-purpose mechanical assemblies across HVAC, plumbing, electrical, and industrial applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall between the fastener head or nut and the mating surface with the split gap seated against the bearing face.
