Flat washers are perfect for increasing the bearing surface under the head of fasteners by distributing the load through the washers and can ensure safe holding; They can prevent bolts or nuts from pulling through the surface. Fender washers are distinguished from standard flat washers by their significantly larger outside Diameter, which creates a larger surface on the fastener, enabling it to withstand more force. 304 stainless steel is a common austenitic stainless steel, typically non-magnetic or weakly magnetic. However, under certain special circumstances, due to the transformation of the austenitic structure into a martensitic structure during cold working, and since the martensitic structure is ferromagnetic, this can cause 304 stainless steel to exhibit slight magnetism. Package includes: 20 PCS 3/8 Fender Washers, Inside Diameter: 3/8 , Outside Diameter: 2 , Thickness: 0.047 . Material: The 3/8 Fender Washers are made of 304 Stainless Steel, which provides great protection from corrosion resistance, high temperature resistance and high tenacity. Performance: The washers are perfect for increasing the bearing surface under the head of fasteners by distributing the load through the washers and can ensure safe holding. Fender washers are distinguished from standard flat washers by their significantly larger outside Diameter, which creates a larger surface on the fastener, enabling it to withstand more force. Application: Suitable for electrical applications, factory maintenance, automotive repairs, sheet metal work, and DIY projects.
