Will these work on my terminals for boat batteries?

Yes, as long as it is a top post battery. Be sure to check size of opening on the terminal you plan on buying. The bigger the battery, the bigger the terminal on the battery. Hope this helps.

I see the video of the negative not tightening. I have the same problem. What have others done to make it tight?

Hello, you can use 2 x Adjustable Spacers. I used the Spacers that came with it. It’s a-tight fit using the Spacers.

What is the block made of? looks like aluminum. what is the hardware made of? is it coated or solid brass ?
