[M12]

■Shape: Hex low 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.
Lower than regular loosening hex nuts.
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
"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: unichrome
Chromate-treated with only luster.
The hexavalent chrome content is rare, and the corrosion resistance is less than chromate. Hexavalent chrome is hazardous and does not comply with RoHS directive. The alternative is trivalent white.
Color is "Silver Color".

Product Features:
Shape
A ring that has a spring effect on the nut (the material called friction ring is SUS301) is integrated into it.
This is a "thin" U nut with a thinner shape than the usual "U-nut".

Features
The spring action of the friction ring creates friction on the male thread, creating a loosening effect.
Can be fixed in an intermediate position.
All metal construction with excellent heat resistance.
