It is designed for use with M10 fasteners and serves to distribute clamp load, reduce surface damage, and prevent fastener pull-through in bolted assemblies. The washer measures 11mm inside diameter, 22mm outside diameter, and 3mm thick. The black oxide finish provides moderate corrosion resistance and reduces light reflection in finished assemblies. This washer is sold individually but must be ordered in multiples of 10.\u003c\/p\u003e\u003cp\u003eThis flat washer is suited for general mechanical assembly, fabrication, and maintenance applications across industrial, commercial, and trade environments. Common install scenarios include structural connections, equipment mounting, and hardware replacement where M10 metric fasteners are specified. It is appropriate for use in steel-to-steel contact applications where case-hardened material is required to resist embedment under load.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCase-hardened 1010 steel construction resists deformation under clamp load\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish for mild corrosion resistance and low-reflectivity appearance\u003c\/li\u003e\n\u003cli\u003eStandard metric dimensions: 11mm ID x 22mm OD x 3mm thick\u003c\/li\u003e\n\u003cli\u003eDesigned for M10 screw size fasteners\u003c\/li\u003e\n\u003cli\u003eMetric measurement system for compatibility with metric fastener specifications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard metric flat washer for use with M10 fasteners in general mechanical and structural assembly applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by any trade or technician working with metric fastener assemblies. Ensure mating surfaces are clean and free of debris before seating the washer. Use appropriate torque specifications for the fastener grade and joint material as defined by project engineering requirements. The black oxide finish is not a heavy corrosion barrier — apply supplemental coating or sealant if the assembly will see prolonged moisture exposure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWasher Type\u003c\/strong\u003e: Standard Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Case-Hardened Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 1010\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: M10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 11mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 22mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement System\u003c\/strong\u003e: Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161807\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GIBRALTAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 63603G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51691490509106,"sku":"63603G","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d0b580c7af0ad14c4912e6f1af566a88.jpg?v=1788285828","url":"https:\/\/voomisupply.com\/products\/gibraltar-63603g-m10-flat-washer-case-hardened-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
