Steel spring washer (trivalent chromium) / FSW-E
Steel spring washer (trivalent chromium) / FSW-E
This product is a spring washer made of high-strength steel (iron) that has been treated with trivalent chromium plating. It is used by inserting it between the head of a bolt or screw and the mating material. By utilizing the spring's rebound force (elastic force) generated when the bolt is tightened, it applies pressure to the joint, helping to prevent loosening of bolts and nuts due to vibrations and impacts. In addition to the mechanical strength unique to steel, it features corrosion resistance from the trivalent chromium plating and is finished with a glossy appearance. The use of trivalent chromium plating, which does not involve hexavalent chromium, makes it suitable for applications that require environmental consideration, and it can be used for a wide range of fastening applications, from general industrial equipment to the assembly of various enclosures.
