It features a 5.3mm inside diameter, a 10mm outside diameter, and a 0.6mm thickness. Manufactured from Grade 316 Austenitic A4 stainless steel, this washer delivers strong corrosion resistance in demanding environments including marine, chemical processing, and outdoor applications. The serrated internal teeth grip the mating surface and the fastener head to resist loosening under vibration or dynamic loads. The uncoated finish is compatible with stainless hardware assemblies where a clean, bare metal surface is required. Licensed trades and industrial maintenance technicians install these washers wherever reliable fastener retention and corrosion resistance are both critical.\u003c\/p\u003e\n\u003cp\u003eThis internal tooth lock washer is suited for M5 screw assemblies in residential and commercial mechanical systems, electrical enclosures, HVAC equipment panels, plumbing fixture brackets, and general industrial fabrication. The Grade 316 A4 stainless construction makes it a preferred choice in wet, salt-air, or chemically aggressive settings where carbon steel or zinc-plated hardware would corrode prematurely. It is sold in a minimum order quantity of 100 pieces, making it practical for stocking hardware kits, service vehicles, or maintenance inventories.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInternal serrated teeth grip fastener head and mating surface to resist vibration-induced loosening\u003c\/li\u003e\n  \u003cli\u003eGrade 316 Austenitic A4 stainless steel construction for superior corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e5.3mm inside diameter sized for M5 screw applications\u003c\/li\u003e\n  \u003cli\u003e10mm outside diameter with 0.6mm maximum thickness for low-profile installations\u003c\/li\u003e\n  \u003cli\u003eUncoated finish maintains consistent contact resistance in electrical and mechanical assemblies\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 6797 and DIN 6798 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard internal tooth lock washer for M5 screw fastener assemblies across mechanical, electrical, HVAC, plumbing, and general industrial applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall with the serrated teeth facing the fastener head or the mating surface to ensure positive gripping action. De-energize any electrical assembly and relieve system pressure on plumbing or HVAC components before servicing fasteners.
