Copper Washers 5/16 x 5/8 (M8 x 16)

Copper washers designed for M8 bolts, measuring 5/16" inner diameter by 5/8" outer diameter. These washers distribute load evenly across fastened surfaces, reducing stress concentration and preventing damage to softer materials. Ideal for plumbing, electrical, and general engineering applications where corrosion resistance and reliable performance are essential. Copper construction offers excellent conductivity and durability in demanding environments.
