Description

■ Shape: Hex nut (built in spring)

The spring built into the nut transforms into the widening and stretching direction when the bolt is installed, and it tightens to the screw threads of the bolt and locks the force where the nut moves in the loosening direction, preventing loosening. Furthermore, it can be used repeatedly.
Tighten using a 12-sided socket wrench.
■ 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".
