Manufactured from high-quality copper material, they offer\nexcellent heat resistance, corrosion resistance, and electrical conductivity\nwhile maintaining a tight seal under working conditions. The flat washer\nstructure increases the bearing surface area, helping to evenly distribute\npressure and reduce stress on fastened materials. The smooth surface finish\nminimizes friction between the nut and bolt, which helps prevent leakage,\nloosening, and dispersion pressure during installation and use. These copper\nsealing rings are suitable for both professional and DIY applications where\ndependable fastening performance is required.Specification: Product Type:\nCopper Flat Washer \/ Sealing Ring Material: High Quality Copper Color: Copper\nMetric Size: M8 Inner Diameter: 8mm Outer Diameter: 12mm Thickness: 1mm\nPackage Quantity: 40 PiecesCompatibility: Designed for use with M8 bolts,\nnuts, and screws, these metric copper washers are suitable for a wide range of\napplications. Common uses include automotive systems, fuel and hydraulic\nfittings, industrial equipment, home appliances, decks, fence construction,\nworkshops, and general mechanical assemblies. Ideal for fastening tasks that\nrequire effective sealing, pressure distribution, and resistance to heat and\ncorrosion.Note: Please confirm the washer dimensions before purchase to ensure\nproper fitment. These washers are intended for M8 fasteners only. Manual\nmeasurement may result in slight dimensional variations. Copper washers may\ndeform slightly after installation to help create an effective seal.Package\nIncluded: 40 x M8 Copper Flat Washers\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n \u003cul class=\"a\"\u003e\n \u003cli\u003eSecure Load Distribution: These copper flat washers provide an increased bearing surface that helps evenly distribute pressure, reducing the risk of bolt or nut heads pulling through the fastened material.\u003c\/li\u003e\n \u003cli\u003eHigh Quality Copper Material: Made from high-quality copper, these washers offer excellent heat resistance, corrosion resistance, and conductivity, providing a tighter seal compared to steel or rubber washers.\u003c\/li\u003e\n \u003cli\u003eSmooth Surface Design: The smooth finish reduces friction between the screw and nut, helping prevent leakage, loosening, and dispersion pressure during fastening applications.\u003c\/li\u003e\n \u003cli\u003eWide Range of Applications: Designed for M8 bolts, nuts, and screws, these copper sealing washers are suitable for industrial use, automotive systems, fuel and hydraulic fittings, home appliances, decks, fences, and workshop projects.\u003c\/li\u003e\n \u003cli\u003e40-Piece Value Pack: Includes 40 commonly used M8 copper washers, offering ample quantity for maintenance, repairs, and long-term replacement needs.\u003c\/li\u003e\n \u003c\/ul\u003e","published_at":"2026-09-16T02:41:19+10:00","created_at":"2026-09-09T13:40:53+10:00","vendor":"Edinstry","type":"Flat Washers","tags":["industrial_Sep2026"],"price":13100,"price_min":13100,"price_max":13100,"available":true,"price_varies":false,"compare_at_price":null,"compare_at_price_min":0,"compare_at_price_max":0,"compare_at_price_varies":false,"variants":[{"id":50650401669357,"title":"Default Title","option1":"Default Title","option2":null,"option3":null,"sku":"B0GH81WVWC","requires_shipping":true,"taxable":true,"featured_image":null,"available":true,"name":"40PCS M8 Copper Flat Washers, 8mm ID 12mm OD 1mm Thick Metric Copper Sealing Rings for Bolts Nuts Fuel Hydraulic Fittings","public_title":null,"options":["Default Title"],"price":13100,"weight":20,"compare_at_price":null,"inventory_management":"shopify","barcode":"Q60122AP40MX","requires_selling_plan":false,"selling_plan_allocations":[],"quantity_rule":{"min":1,"max":null,"increment":1}}],"images":["\/\/leoforward.com\/cdn\/shop\/files\/B0GH81WVWC.jpg?v=1788925255","\/\/leoforward.com\/cdn\/shop\/files\/41r-kcDi56L.jpg?v=1788925255"],"featured_image":"\/\/leoforward.com\/cdn\/shop\/files\/B0GH81WVWC.jpg?v=1788925255","options":["Title"],"media":[{"alt":null,"id":41956211163373,"position":1,"preview_image":{"aspect_ratio":1.0,"height":500,"width":500,"src":"\/\/leoforward.com\/cdn\/shop\/files\/B0GH81WVWC.jpg?v=1788925255"},"aspect_ratio":1.0,"height":500,"media_type":"image","src":"\/\/leoforward.com\/cdn\/shop\/files\/B0GH81WVWC.jpg?v=1788925255","width":500},{"alt":null,"id":41956211196141,"position":2,"preview_image":{"aspect_ratio":1.0,"height":500,"width":500,"src":"\/\/leoforward.com\/cdn\/shop\/files\/41r-kcDi56L.jpg?v=1788925255"},"aspect_ratio":1.0,"height":500,"media_type":"image","src":"\/\/leoforward.com\/cdn\/shop\/files\/41r-kcDi56L.jpg?v=1788925255","width":500}],"requires_selling_plan":false,"selling_plan_groups":[],"content":"\u003ch3\u003e40PCS M8 Copper Flat Washers, 8mm ID 12mm OD 1mm Thick Metric Copper Sealing Rings for Bolts Nuts Fuel Hydraulic Fittings\u003c\/h3\u003e\n\u003cp id=\"b\"\u003eFeature: These M8 copper flat washers are designed to provide reliable sealing\nperformance and stable load distribution for a wide range of fastening\napplications.
