Sold in a pack of 50, this washer features serrated external teeth that bite into the mating surface and fastener head to resist loosening caused by vibration and torque. The zinc plating provides basic corrosion resistance for general indoor and light-duty outdoor applications. With an inside diameter range of 0.640 to 0.659 inches and an outside diameter range of 1.045 to 1.070 inches, the washer seats correctly on standard 5\/8 inch fasteners. Thickness is 0.045 inches. Licensed tradespeople, maintenance technicians, and assembly workers rely on this type of washer to secure panel hardware, structural connections, and equipment mounts.\u003c\/p\u003e\n\u003cp\u003eExternal tooth lock washers in this size range are used across a wide range of applications including electrical panel assembly, HVAC equipment mounting, plumbing fixture attachment, and general mechanical assembly. The external tooth design provides greater holding force compared to internal tooth versions, making it a practical choice where vibration is a consistent factor. This washer is appropriate for residential and light commercial work where Grade 2 steel and zinc-plated finish meet the job requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExternal tooth design bites into fastener and mating surface to resist vibration-induced loosening\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides basic corrosion resistance for general service environments\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction suitable for standard-duty fastening applications\u003c\/li\u003e\n  \u003cli\u003eInside diameter range 0.640 to 0.659 inches fits standard 5\/8 inch fasteners\u003c\/li\u003e\n  \u003cli\u003eOutside diameter range 1.045 to 1.070 inches for adequate bearing surface coverage\u003c\/li\u003e\n  \u003cli\u003ePack of 50 supports production assembly, service calls, and shop stock\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 5\/8 inch screws and bolts in general mechanical, electrical, HVAC, and plumbing fastening applications where an external tooth lock washer is specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall this washer between the fastener head and the mating surface with the teeth facing the fastener head for maximum holding effect.
