Description

■ Shape: Countersunk Spring Washer JIS
Round washers with a flip over plate. This shape creates a "spring recoil" and provides a strong anti-loosening effect. It is also called "countersunk washer".
The countersunk spring washers are prescribed by the JIS standard, and there are two types of "screw (1 type)" for general use bolts, small screws, and nuts, and "cap bolts (2 types)" for use with cap bolts, and for each other are "light load (L)" and "heavy load (H)".

■Material: Stainless steel
Most representative stainless steel (equivalent to SUS304)
The strength is almost equal to "iron".
Excellent corrosion resistance and good mechanical properties.
Although it is normally not magnetic, it can harden due to cold processing, and it may cause magnetism.

■Surface treatment: fabric
Surface treatment/plating is untreated.
Therefore, corrosion resistance and appearance are the characteristics and color of the material itself.
