[M12]

■Shape: Enzart
Insert nut for reinforcing the screw part on soft materials such as aluminum and resin.
The inner and outer diameter of the tapping insert is threaded and has a cut blade such as a split groove and three-hole type.
No pre-tap is required for the bottom hole and is resistant to pulling and loosening

■ 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" and is an alloy of iron containing 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".

Product Features:
307 Type 3 Hole Type
Suitable for both hard and soft parts such as mild steel and high strength aluminum alloy.
※ May not be used with super strong forged aluminum.
If used with the tap, it may be used with iron or heat treated aluminum.
