There are some screws on the underside of this bracket that don't look like they really do anything. What are those for?

Those screws really make a huge difference. The special feature of these screws is that they are stops. When you insert your camera on the bracket, you have the option to displace your camera to both sides (very useful in macro photography). If for some reason your camera is not placed enough pressure, this slip only to the stops. I think is not a good idea remove this stops.

They keep the plate from accidently sliding out of a slightly loose quick release mount.

There are no screws, just threaded holes for tripod mounting or other mounts.

I wish I could answer that for you. I ended up returning the bracket as it didn't work with my Canon 60D

This bracket is designed to be used with an Arca Swiss style ball head which has two plates connected by a threaded screw that clamp onto this style of bracket. The additional screws seen on this bracket are "safety stops" that will prevent your camera or lens from sliding completely from the ball head when you loosen the tightening screw. They are a nice feature but can be removed if desired with a small allen wrench.

The small screws on the underside are stops. They keep the plate and the camera from sliding through the clamp and possibly falling when the clamp is loosened.

As far as I can tell, nothing. In fact one has fallen out. Used on a Canon 5d Mark III.

Maybe. My unit is new and I haven't needed to look into that. But I can see that there are 4 screws on the backside of the unit. If you have a unit already, open it up and take a look inside.

adam w evans answer seems like a great answer. I didn't have the problem you describe, nor have I had to adjust the screw mentioned.

They're self-tapping. Just screw them in.I wasn't exactly impressed by the provided screws and the location of the holes pre-drilled in the metal brackets, though. So, I drilled new holes and used better screws. The standard hardware will work. Mine will just work better.

Loosen the bolt on the bracket bar on the right side a little. See if that helps.

You installed the bracket upside down. Unscrew it and flip it over and reinstall it and that will fix your issue.

Screws are vertical for attachment. The set screws to hold on bracket are vertical also.

Those "screw holes" are cosmetic, they don't exist. I suppose you could carefully drill actual screw holes and mount it, but it's all thin plastic.

I have not noticed any manufacturing marks on the bracket. There are none visible on the outside of the bracket.

Actually, there's are 2 little holes on the back that looks like they would slide over a screw that was screwed into a wall. I don't know if screws were included in the box, because I threw that out months ago.

I don't know off hand. However, given the multiple hole patterns on various brackets which are included, I would be surprised if they didn't work for you.

Hi,On the bottom of the unit are 2 types of holes. One hole is where the screw goes in to hold unit together, the other hole looks like a round circle with a lines at each end. I know terrible description. There are 4 of them. I think --0-- this looks similar to what I am trying to describe. Hope this helps.

I agree with the maybe. I bought the optional extension rail. The rail provided the verticle surface needed to connect the bracket. I love this purchase.

My opinion is this bracket is a piece of junk. If you buy it you're just throwing away your money. You would be better off using duck tape. I'm sorry if I come away harsh but I wouldn't use this bracket again if they gave it to me free including shipping.

I see four holes through the frame on both ends that might be used to install brackets. Hope that helps.

Yes, that's the way I assembled mine. I believe they are screws meant just for this sort of plastic. I've had no issues with mine since installation.
