It features a serrated external tooth profile that bites into mating surfaces under torque, resisting loosening from vibration and dynamic loads. Manufactured from Grade 18-8 austenitic stainless steel to the A2 designation, it offers solid corrosion resistance in wet, humid, or mildly chemical environments. With a 5.3mm inside diameter and 10.0mm outside diameter, it seats cleanly on M5 screws and bolts. This washer ships in a minimum quantity of 100 pieces per order and is appropriate for mechanical, electrical, and plumbing assemblies where fastener retention is critical.\u003c\/p\u003e\n\u003cp\u003eThis external tooth lock washer is used wherever M5 fasteners require positive locking in assemblies subject to vibration or thermal cycling. Typical applications include electrical panel mounting, equipment enclosures, HVAC component fastening, pump and motor mounting, and general mechanical assembly. The stainless steel construction makes it suitable for outdoor, marine-adjacent, or corrosion-prone environments. Trade professionals in electrical, plumbing, HVAC, and mechanical contracting will find this washer appropriate for both original installation and maintenance or repair work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExternal tooth serrated profile bites into fastener and mating surface to resist vibration loosening\u003c\/li\u003e\n  \u003cli\u003eGrade 18-8 austenitic stainless steel with A2 designation for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e5.3mm inside diameter fits M5 screws and bolts\u003c\/li\u003e\n  \u003cli\u003e10.0mm outside diameter provides adequate bearing surface for standard M5 hardware\u003c\/li\u003e\n  \u003cli\u003e0.6mm thickness for low-profile installations with tight clearance\u003c\/li\u003e\n  \u003cli\u003eSold in packs of 100 to support production, service, and maintenance workflows\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with M5 screws and bolts as an OEM-style or aftermarket locking washer in mechanical, electrical, and plumbing assemblies requiring external tooth lock retention.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall with the teeth facing the fastener head or nut, not the base material, to allow the serrations to grip during final torque.
