I have never tried to use them. It looks like you need to have an arbor press or something like it to install them..... You *might* be able to 'pull' them in from the other side by tightening a nut down (Kinda like carriage bolts on wood) I wonder how well they would hold in the soft copper?

THis?

Exactly.

Looks like only a square-bottom hole (with end mill) would serve to countersink and still let it bite.

taking all this in i'm thinking to make my own bus bars with 1/8" x 1.5" wide copper bar purchased here.

This provides for an apacity of 390 which is well above the 250 required.
I will drill 7 - 3/8" holes with the inverter and controller lugs in the middle and 3 battery lugs on either side and bolt the lugs to the bar.
Using 4 AWG cables to connect the batteries to the bus bar.
1.5' wood stand offs for the bus bar.
Is there a specific bolt/nut i should use or just regular steel.
any comments/improvements on this?
thanks in advance the dialogue here has been great.

We usually use stainless bolts & nuts.
There is some problem with galling when stainless is used on stainless.
Brass would be good too, or brass nuts on stainless bolts.

If you use wood, make sure it isn't going to weather, eventually crack, and let a live battery bus come loose.

Make sure holes in busbar are far enough for the size ring terminals you're using. I got pre-drilled bars and only fit every other hole.
