Place the washer under the bolt or nut, ensuring it is correctly aligned with the fastener hole. Tighten the fastener to the manufacturer’s specified torque, taking care not to over-tighten, which could damage the washer or the components being joined.

Common Issues and Troubleshooting

Common issues with plain washers include wear, deformation, and improper installation. Wear can occur over time due to friction and load, while deformation may result from excessive force or incorrect sizing. Improper installation can lead to misalignment and increased friction. To troubleshoot these issues, regularly inspect washers for signs of wear or damage, ensure they are correctly sized for the application, and follow proper installation procedures.

Maintenance Tips

Regular maintenance of plain washers is important to prolong their service life and ensure continued reliable performance. Inspect washers during routine maintenance checks for signs of wear, corrosion, or deformation. Replace any damaged washers promptly to prevent further issues. Additionally, keep mating surfaces clean and free of debris to reduce the risk of washer failure.
