M6 M8 carbon steel zinc plated galvanized thin round hard flat washers manufactured to DIN125 standards, designed for industrial fastening applications requiring corrosion resistance and reliable performance.

• Manufactured through precision stamping from iron plates
• Reduces friction and prevents surface damage during tightening
• Distributes pressure evenly to prevent material deformation
• Zinc plating provides excellent corrosion resistance
• Stabilizes screw head when hole diameter exceeds bolt size
• Available in custom sizes according to customer requirements

• Prevent bolt/nut head sinking into holes or grooves
• Protect soft materials from damage during assembly
• Improve stability when mating with oversized holes
• Enhance locking capability by increasing friction surface
• Provide insulation and improve waterproofing with non-metallic variants

Materials: Carbon Steel, Stainless Steel (including SUS316L, SUS329J4L), Aluminum, Brass, Titanium, ZAM

Surface Coatings: Galvanized, Yellow Zinc, Chrome, Nickel, Black Oxide, Trivalent Chrome, Dacro, and various industrial finishes

All flat washers undergo rigorous inspection using precision equipment including micrometers, torsion machines, durometers, and coating thickness gauges to ensure dimensional accuracy and performance reliability.

We offer OEM/ODM services with flexible drawing formats (DWG, PDF, PNG) to meet specific customer requirements for specialized applications.
