Is Monotaro fast?Is it late?

Self-tap screw "Sunlock".When the tap of thin aluminum material such as front mounting becomes sloppy, there are various ways to revive it.

This sun lock screw does not need to be tapped or pinched with clip nuts.

It's useful!This! !!

I asked for a monotaro for about 500 yen at most, but it hasn't been delivered even after three days.

Is it early?Is it late?Is it convenient?
