Description

■ Head Shape: Solon

The seat side has been serated) hex nut with double sided jagged countersunk washer (countersunk spring washer). In addition to the resilience effect of the countersunk washer, the serate chew between the nut and washer and the serate chewing between the washer and the opponent provides a loosening effect.
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: 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:
