Internal tooth lock washers grip the fastener and mating surface simultaneously, resisting loosening caused by vibration and torque. The hardened steel teeth bite into both surfaces when the fastener is tightened, maintaining clamp load over time. This package contains 100 washers. Electricians, HVAC technicians, plumbers, and general trade mechanics use internal tooth lock washers in panel assemblies, equipment mounting, and mechanical connections where vibration is a concern.\u003c\/p\u003e\n\u003cp\u003eInternal tooth lock washers in this size range are standard hardware in residential and light commercial applications. They are used in electrical enclosures, HVAC unit mounting brackets, motor housings, and structural fastening assemblies wherever a 1\/2 inch fastener requires positive locking. The zinc plating provides corrosion resistance suitable for indoor and protected outdoor installations. The 100-piece pack is sized for jobsite or shop stock.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInternal tooth design grips both fastener head and mating surface to resist vibration-induced loosening\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction with zinc plating for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eInside diameter range of 0.512 to 0.529 inches fits standard 1\/2 inch fasteners\u003c\/li\u003e\n  \u003cli\u003eOutside diameter range of 0.867 to 0.883 inches provides broad bearing surface\u003c\/li\u003e\n  \u003cli\u003e0.039 inch thickness for consistent clamp load\u003c\/li\u003e\n  \u003cli\u003e100-piece pack supports bulk jobsite and shop use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 1\/2 inch screws and bolts in residential and light commercial mechanical, electrical, and HVAC fastening applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires no special tools beyond the appropriate wrench or driver for the mating fastener.
