Serrated Anti-loosening Belleville Washer

Serrated conical spring washer · vibration-proof bolted joints

Serrated anti-loosening Belleville washers combine the spring preload of a conical disc with radial serrations that bite into the mating surface, keeping bolted joints tight under vibration and thermal cycling.

Conical spring action maintains clamp load
Radial serrations resist loosening under vibration
Hardened spring steel or stainless steel
Zinc flake or zinc-nickel coatings for corrosion resistance

Material: Carbon steel (SPCC, 45#), spring steel (65Mn), stainless steel (SS304 / SS316), copper, brass, aluminum
Standard: DIN / ISO / ANSI (IFI) / JIS / BS / AS / GB, or custom drawing
Thickness: 0.1 – 10 mm
