Another option, at least one I am using to distribute battery power to my driving lights,is to use barrier strips (I got mine from radio shack) they look like this and you can get them with more posts than in this photo, the one I used has 8:
You can see the barrier strip in this photo of the inside of my light relay box in my truck on the right side of the box underneath the relay.
I have one power wire coming in from the power distro studs on the front of the engine bay Fuse/power distribution box.
A handy thing is you can get jumpers to connect the posts together so you only have to run one power (or ground) to the block and can connect as many things as you have open posts for:
I cut one in half and use 4 connections for power and 4 for grounds for the relays in the above box.
