Monitor arm mounting parts for grommet fixing

I bought a monitor arm from Sanwa Supply.
I installed it using clamp mounting, so I have the grommet mounting parts left over.

This is for those who want to change from clamp mounting to grommet mounting.

The monitor arm is a gas spring type, single arm, from the 100-LAC003 series.

This is the optimal parts set for installing a monitor arm.

Hex wrench and M6 bolts are not included.
Please reuse the M6 bolts you are currently using.

Thank you for looking.
