It features an inside diameter of 0.267 inches and an outside diameter of 0.454 inches, with a thickness of 0.025 inches. The external tooth design bites into both the fastener bearing surface and the mating workpiece to resist loosening under vibration and dynamic loads. Manufactured to Grade 2 steel standards with a zinc-plated finish for basic corrosion resistance, these washers are a standard hardware consumable used across HVAC, electrical, plumbing, and general mechanical assembly work. This listing covers a box quantity of 100 pieces.\u003c\/p\u003e\n\u003cp\u003eExternal tooth lock washers in this size range are commonly specified in light-gauge sheet metal assemblies, electrical panel and junction box installations, HVAC equipment mounting, and general equipment fabrication. The countersunk feature accommodates flush or near-flush seating in appropriate applications. These washers are installed by HVAC technicians, electricians, plumbers, and general mechanical trades wherever 1\/4 inch fasteners require vibration-resistant retention.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExternal tooth design bites mating surfaces to resist vibration-induced loosening\u003c\/li\u003e\n  \u003cli\u003eInside diameter of 0.267 inches fits standard 1\/4 inch screw fasteners\u003c\/li\u003e\n  \u003cli\u003eOutside diameter of 0.454 inches with 0.025 inch thickness\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides basic corrosion resistance for indoor and sheltered applications\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction for standard-duty fastening applications\u003c\/li\u003e\n  \u003cli\u003eCountersunk feature supports flush seating where required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 1\/4 inch screw fasteners in standard-duty steel and sheet metal assemblies across HVAC, electrical, and mechanical trade applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall with the teeth facing the fastener head or nut, not the workpiece surface, to ensure proper locking engagement.
