■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: Fine
Finer than the nations most standard pitch (coarse) prescribed by ISO (International Organization for Standardization) standard. Compared to coarse threads, it has a shallow valley and a larger cross-section area which makes it less likely to loose. Please note that there are multiple sizes of pitch depending on the thickness of the screw. Primarily used where precision is required.

■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: Chromate
Chromate-treated for corrosion resistance
Chromate coating is more corrosion resistant than unichrome It contains harmful hexavalent chromium and does not comply with RoHS directive. The alternative is trivalent white.
Shades are "Tan".

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.
