[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: Left screw (coarse)
It is also called "reverse screw" by turning the left and screwing into the screw.
Pitch is the most standard pitch in the country prescribed by ISO (International Organization for Standardization) standard. The screw to attach the fan blade is left screw.

■Material: Stainless steel
Most representative stainless steel (equivalent to SUS304)
The strength is almost equal to "iron".
Excellent corrosion resistance and good mechanical properties.
Although it is normally not magnetic, it can harden due to cold processing, and it may cause magnetism.

■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.
Can be fixed in an intermediate position.
All metal construction with excellent heat resistance.
