Description
Size:M8
■Shape: Hex nut (with friction ring)
Hex nut for loosening and a spring-action friction ring on the top creates friction on the screw such as bolts to prevent loosening. 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 black
It has the same corrosion resistance as the "black chromate" and has the same possibility of self-healing. Unlike hexavalent chrome, it is non-toxic and compliant with RoHS directive. Therefore, it is used as an alternative to black chromate. Color is "Black".
