What is the metal bar in this picture specifically named?
 

Sorry for a such a simple question, but one of the biggest hurdles my team has to worry about is specific names for mechanical and electrical components when we can't find a serial number or something similar.

What are the beams that are holding these two tread's together called? We ordered a set of treads from AndyMark and want to have everything we need to set them up when they arrive.

(Edit: Image was too big)
It's the picture under the More category.

Thank you for your time and help! Is there a better forum to ask questions like this on for future reference?

Are you talking about the Rev extrusion? Or are you talking about the turn buckles?

If it's the Rev extrusion I would stock up on mounting hardware. They use lp 10/32 nuts I believe which are hard to find. Andymark sells the bolts and nuts. Buy the nuts from them but I would buy the bolts from somewhere else as they are more easily found for cheaper and the Andymark ones strip really easy if you use a drill.

Are you referencing the turn-buckle? Basically, a threaded extrusion with eye hooks on each side, useful for providing length adjustment.

Nuts are used to mount things into the T-slots of the REV extrusion, not to mount to the ends. To mount to the ends of the extrusion, one either taps the center hole for 1/4-20 or uses a #10 bolt through the entire piece of extrusion.

I know sorry was not clear.

Once the chassis is built you have to interface with it so that's why I recommenced buying some brackets and hardware.

Kinda unclear which parts you are asking about but the circular-looking things are called churro.
