It seats under an M2 screw head or nut, and its serrated internal teeth bite into both the fastener bearing surface and the mating workpiece to resist loosening from vibration or dynamic loading. With a 2.2mm inside diameter, 4.5mm outside diameter, and 0.3mm thickness, this washer is sized precisely for M2 fastener assemblies. The uncoated stainless steel finish provides corrosion resistance without added plating thickness that could affect fitment tolerance. Sold in a minimum quantity of 200 pieces per order.\u003c\/p\u003e\u003cp\u003eThis washer is suited for light-duty fastener assemblies in HVAC controls, electrical enclosures, panel hardware, and similar trade applications where M2 fasteners are used and vibration loosening is a concern. The 18-8 Grade A2 stainless steel construction makes it appropriate for indoor or mildly corrosive environments. Electricians, HVAC technicians, and panel fabricators working with small-diameter fasteners in control assemblies will find this washer a standard fit for M2 screw applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eInternal serrated tooth design bites into fastener and workpiece surfaces to resist loosening under vibration\u003c\/li\u003e\n\u003cli\u003e18-8 austenitic stainless steel, Grade A2 construction for corrosion resistance\u003c\/li\u003e\n\u003cli\u003e2.2mm inside diameter sized for M2 screws\u003c\/li\u003e\n\u003cli\u003e0.3mm thickness maintains low profile in tight fastener assemblies\u003c\/li\u003e\n\u003cli\u003eUncoated finish avoids plating buildup that can affect tolerance-critical fits\u003c\/li\u003e\n\u003cli\u003eSupplied in minimum order quantities of 200 pieces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with M2 screws and nuts in standard M2 fastener assemblies across electrical, HVAC control, and light mechanical applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires no special tools beyond standard hand or power drivers appropriate for M2 fasteners. Place the washer under the screw head or nut with the teeth facing the bearing surface before driving. Ensure mating surfaces are clean and free of debris so the teeth can seat properly. Verify fastener torque is appropriate for the assembly material to allow the teeth to engage without damaging the substrate.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTooth Type\u003c\/strong\u003e: Internal tooth, serrated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 2.2mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 4.5mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.3mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 18-8 austenitic Grade A2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds (package)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 200 pieces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMilitary Specification\u003c\/strong\u003e: Does not meet military specifications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SIW8X0200-200BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51697854611762,"sku":"SIW8X0200-200BX","price":1256.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/61091f6213a5ee195cdb84c052125849.jpg?v=1788355054","url":"https:\/\/voomisupply.com\/products\/value-collection-siw8x0200-200bx-m2-lock-washer-ss-18-8","provider":"Voomi Supply","version":"1.0","type":"link"}
