■Shape: Bag nut (with friction ring)
A loosening nut with a friction ring on the top of the hex nut and a domed metal over it.
The spring effect on the top of the friction ring creates friction on the screws such as bolts and other parts to prevent loosening. In addition, the screws such as bolts are not exposed than the screw hole, so they look good and improve safety.
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: Trivalent black
It has the same corrosion resistance as the "black chromate" and has the same possibility of self-healing.
Unlike hexavalent chrome, it is non-toxic and compliant with RoHS directive. Therefore, it is used as an alternative to black chromate.
Color is "Black".

Product Features:
Bag nuts are integrated into a spring ring (friction ring) that came together with the nut.
The material of friction ring is SUS301.
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.
