Description

■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: Wit

The Wit Standard is the UK standard. Unlike other standards, the thread angle is 55° and the pitch is roughness than the nations most standard pitch (coarse) prescribed by ISO (International Organization for Standardization) standards.
■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".
