Description

■Shape: Hex nut with countersunk spring (large)

Large countersunk washers (countersunk washers) are integrated into the seat side of the hex nut. The elastic effect of the countersunk washer absorbs various vibrations and prevents loosening due to spring reaction.
The nut and countersunk washer feature a rotating mechanism to reduce damage to the original equipment during installation.
Use a tool such as a spanner or wrench to tighten it.
■ Thread Shape: Coarse

It is the most standard pitch in Japan as prescribed by ISO (International Organization for Standardization) standard. The most frequent distribution in Japan.
■Material: Iron

Iron is steel. Steel is an alloy of iron containing less than 2% carbon.
Although it is commonly used in many circulations, it is cheap materials, but due to the downside of it is easy to rust, many surface treatments will reduce corrosion.
■Surface treatment: Trivalent white

It has the same corrosion resistance as "chromate" and has the same possibility of imitation self-healing.
Unlike hexavalent chrome, it is non-toxic and compliant with RoHS directive. So it is used as an alternative to unichromate/chromate.
Color is "Silver Color".
Product Features:

The elasticity of the countersunk spring washer creates a loosening effect.
The countersunk spring washer has a large tightening area, so the tightening load will be larger.
All metal construction with excellent heat resistance.
