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: Chromate

Chromate-treated for corrosion resistance
Chromate coating is more corrosion resistant than unichrome It contains harmful hexavalent chromium and does not comply with RoHS directive. The alternative is trivalent white.
Shades are "Tan".
