Description

■ Shape: Hex nut (set of 2)

Hex nut for loosening and tightening using two convex and recessed nuts. The convex nut has a shape that promotes wobble action. When tightening with concave nuts, friction on the screws such as bolts and other parts of the screw to create a loosening effect.
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 (SCM435)

It is called chrommolybdenum steel alloy steel for mechanical structures, and is an alloy steel with good hardening properties.
Contains Cr (chromium) for better corrosion resistance than "iron".
Stronger than "iron" or "S45C".
■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".
