Description

■ Shape: Hex nut (built in spring)

The spring built into the nut transforms into the widening and stretching direction when the bolt is installed, and it tightens to the screw threads of the bolt and locks the force where the nut moves in the loosening direction, preventing loosening. Furthermore, it can be used repeatedly.
Tighten using a 12-sided socket wrench.
■ 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: 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.
