Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • In the actual procurement process of flat washers, it is recommended to prioritize checking key specification parameters such as inner diameter, outer diameter, and thickness to ensure that they match the size of bolts or nuts and avoid affecting assembly results due to tolerance issues.
  • For different application scenarios such as mechanical equipment sealing or electronic component insulation, flat gaskets made of materials such as stainless steel, rubber, or nylon can be considered to meet corrosion resistance or buffering requirements.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support. Such suppliers usually provide more stable delivery capabilities.
  • For use in high-frequency vibration environments, it is recommended to choose flat gaskets with high hardness and surface treatment to reduce the risk of deformation or wear during long-term use.
