Washers are indispensable auxiliary elements in fastener systems. Though small in size, they bear the important mission of protecting connection surfaces, preventing loosening, and uniformly distributing loads. The nickel alloy washers supplied by Hefei Tailan Metal Co., Ltd. are manufactured from high-quality nickel-based alloy plates or wires through multiple precision processes including stamping, forming, solution heat treatment, and surface treatment. Featuring precise dimensions, moderate hardness, and excellent corrosion resistance, they are specifically designed for fastener connections under demanding conditions such as offshore engineering, petrochemical processing, and nuclear power generation.
Washer Types:
- Flat Washer: Increasing bearing area, protecting connection surfaces
- Spring Washer: Preventing loosening, providing preload
- Lock Washer: Better anti-loosening performance, suitable for vibration conditions
- Square Taper Washer: Leveling on sloping surfaces such as I-beams, channels
Supply Range
Nominal Diameter (d): M3 – M100 (for bolt diameter); Larger sizes negotiable
Inner Diameter (ID): Determined by bolt diameter, typically bolt diameter + 0.5mm – 1.0mm
Outer Diameter (OD): Determined by standard and specification, typically about twice the ID
Thickness (T): 0.5mm-10mm (determined by standard and specification)
Surface Condition: Pickled, Passivated, Polished optional
Special Specification Notes:
Extra-Large Washers: Available with OD 3-5 times ID, for soft material connections
Ultra-Thin Washers: Available from 0.2mm thickness, for precision adjustment
Non-Standard Sizes: Various non-standard IDs, ODs, and thicknesses available as per drawings
Multiple Types Available, Adapting to Different Conditions
- Flat Washers: Increasing bearing area, protecting connection surfaces, suitable for most applications
- Spring Washers: Providing elastic preload, preventing loosening, suitable for vibration conditions
- Lock Washers: Toothed design, better anti-loosening performance, suitable for critical connections
- Square Taper Washers: Leveling on sloping surfaces such as I-beams, channels, ensuring bolts are perpendicular to the surface
