Material/Finish

SWA-F-GJ
Main Body Steel
Electrical Corrosion Prevention Coating

Application

For outdoor screw tightening, such as fixing outdoor components of air conditioners, etc.

Characteristics

  • When the thread part and mating side materials differ, this prevents the corrosion (galvanic corrosion *1) that occurs due to adherence of water droplets, etc.
  • The surface treatment reduces the electrical conductivity, and suppresses the battery action between dissimilar metals which is a source of corrosion.
  • The effective period of galvanic corrosion prevention is about 5 times longer than hot dip zinc plating.
  • Suitable for fixing aluminum parts and materials that are used outdoors.
  • The surface treatment has a high adhesiveness, and provides excellent anti-rust effects for the washers themselves, as well.

*1: In locations where dissimilar metals are in direct contact, when water droplets, etc., adhere between the two metals, battery action can result in corrosion. This is also called galvanic corrosion.


Precautions for Use

The anti-corrosion effects vary depending on the usage conditions. Use periodic inspections to perform corrosion checks and replacements.
