I need replacement screws for H 20 T will these screws fit and will these caps fit as well. Thank you

Hi, the size of the screws is M4*8, which you can purchase it on local store.

How big are the screws

The screw's size of the motor cap is M4*8.

Does this come with a tool to get lugs off? If not what size hex key does it require.

We will give the tools to you.
