Package Contents: 100 pieces of M5 flat washers. Inner Diameter: 5mm, Outer Diameter: 10mm, Thickness: 1mm. T3 Copper Annealing Process: Annealing is a heat treatment process applied to copper, particularly T3 copper, to soften and make it more workable. Copper construction ensures resistance to wear, rust, and corrosion, reducing the need for frequent maintenance and replacement. Function: Copper washers are designed to provide a wider bearing surface for bolts, screws and nuts, used to carry the load of threaded fasteners over a larger surface area. This helps prevent damage to the connecting material and reduces the risk of concentrated force. Easy to Use: Flat washers are commonly used under bolts or nuts to secure bolts with a smaller diameter than the washer hole to provide a smooth bearing surface and reduce the possibility of the fastener loosening due to contact with uneven surfaces. Wide Application: Suitable for various repairs and installations in most mechanical industries such as automobiles and ships, and are also suitable for parts replacement of various pumps, oil pan plugs, office equipment, automation equipment, and electronic equipment. Also suitable for most furniture, DIY handmade projects, etc. Through annealing process, T3 copper material can benefit from:Improved grain structure, enhancing material toughness and ductility.
Ensure that the metal surface and flange sealing surface fit tightly to reduce the possibility of leakage
Reduced residual stresses, minimizing deformation and cracking risks.
Enhanced machinability, making it easier for further processing and shaping.
