[M12]

■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: 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: Brass
Brass has excellent conductivity and is used for strong and weak electrical equipment and electrical components.
Because it has excellent corrosion resistance, it is often used with fabric when used with internal terminals, but the surface treatment such as nickel-plated processing improves corrosion resistance and improves decorability.

■Surface treatment: fabric
Surface treatment/plating is untreated.
Therefore, corrosion resistance and appearance are the characteristics and color of the material itself.

Product Features:
Shape
A ring that has a spring effect on the nut (the material called friction ring is SUS301) is integrated into it.

Features
The spring action of the friction ring creates friction on the male thread, creating a loosening effect.
Prevents premature fall off even if the shaft strength is reduced.
Can be fixed in an intermediate position.
All metal construction with excellent heat resistance.
The shape will vary by 1 or 2 types depending on the dimensions.
No special tools required for fastening.
Comes with a manufacturers own engraving.

Precautions for Use:
Please use the bevel tip with the screw accuracy of JIS6g (grade 2) on the other bolt.
Please make sure that the screw is at least 2 pitches from the friction ring for full functionality.
Cannot be screwed on the friction ring side.
