Washers
Washers are essential components in bolted connections, providing a smooth bearing surface to distribute loads, prevent damage, and maintain bolt tension. Available in plain, spring, and heavy-duty types, washers are widely used in foundation anchoring systems to ensure structural integrity and long-term performance.

Manufacturing Method & Tolerances
Manufacturing Method:
Washers are blanked or laser-cut from sheet metal or forged bar, then machined or flattened to meet dimensional tolerances. Heat treatment and coating are applied based on mechanical or environmental demands.
Tolerances:
- ID & OD: As per IS / DIN standard
- Thickness: ±0.3mm or per drawing
- Surface finish: Coating thickness as per ISO 10684 / ASTM
Applications & Usage
- Used with foundation bolts and rods for load distribution
- Prevents bolt head/nut embedding into surfaces
- Common in tower bases, machinery footings, and plates
- Ensures bolt tension in vibrating structures
- Found in power plants, bridges, and infrastructure installations
