Description

■Shape: Flanged bag nut
The domed metal is encased on one side of the hex nut, so the bolts and other screws are not exposed, making them look good and more safe. In addition, the other side has a seat that is larger than the width of the two sides, which increases the tightening strength and prevents 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: 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".
