M METERXITY 100-Pack Copper Washers, Metric M5x9x1mm Copper Sealing Washers for Bolts Screws Nuts for Automotive/Machinery/Plumbing, Flat Metal Flat Ring

• [Multipurpose Use] - These crush washers are widely used in automotive oil pans, fuel lines, and hydraulic systems, as well as in electronics, industrial machinery, and household appliances. They can be highly matched with screws, nuts, and bolts of the same size, providing a stable and aesthetically pleasing fastening effect
• [Durable Flat Washers] - Made of copper, our copper sealing washers feature excellent heat resistance, electrical conductivity and corrosion resistance, are durable and have better sealing performance than steel gaskets and rubber gaskets. Ensure long-lasting durability in damp and chemically corrosive environments, effectively reduce wear and deformation, and extend service life
• [Size & Package] - 100Pcs x Flat Washer; Outside Diameter: 9mm/0.35 in; Inside Diameter: 5mm/0.2 in; Thickness: Thickness: 1mm/0.04 in, enough quantities for your long-term use
• [Advantage] - The flat sealing crush washers have a uniform thickness and smooth edges, which effectively disperse the load pressure of bolts and nuts, and prevent the surface of the fastened material from being damaged or loosened. Their smooth surface can reduce friction and play a role in isolation and leakage prevention. They can be used in combination with an anti-loosening washer to enhance connection stability
• [Installation] - Please ensure that the flat washers can be used with the corresponding bolts or screws. Please place the flat washers under the bolt head/nut to ensure that they fit the contact surface flatly
