Movcam top handle threading

Hey guys, it seems like the Movcam top handle isn't designed to put a screw all the way through both sides. Is this true?
The threads of one hole don't line up with the threads of the hole on the other side of the handle. The screw stops once you hit the threads..

I guess I can't mount in this way. The reason I did this is I have a female hole in the piece I need to mount.

I don't know what a female hole is (aren't they all?) :)

I don't have that handle, but normal machining processes would not run the tap through both holes in one machining step. So they don't line up. If the thing you are attaching has threads and you don't want to drill out any of the threads, I suggest you use a set screw instead of a bolt.

Run it backwards into the hole you want to mount to until it is flush with the surface. Then, reach through the other hole with an allen wrench and tighten down. You still will have the thread alignment issue between the two items, but you can fix that with some shim material. Not ideal, but it will leave the items intact without drilling the threads out one of the holes.

Once tightening the set screw onto the mounted piece of equipment, will it stay in place (not rotate)? Or will it rotate freely? due to no friction on the other side of the screw (inside the Movcam arm)?
 
Yes, if you don't shim it up, it will flop around freely (a drop of threadlock with prevent this). The real answer is to drill out the threads. My suggestion is just a desperate option if you don't want to mess up the handle.

It looks like the handle has two size holes (3/8" and 1/4"?). Can you use a 3/8" position and slip a 1/4" bolt through it? It may still hurt the threads as the bolt rubs up against them. Ugly.

Perhaps a better approach is this? http://www.ebay.com/itm/New-1-4-Mal...751?pt=LH_DefaultDomain_0&hash=item19debf986f

or this? http://www.ebay.com/itm/spigot-scre...ens_Adapters_Mounts_Tubes&hash=item27e88103e2

Both would require a shim to get the thing to tighten in the position you want. You can use anything for a shim - cereal box cardboard, paper....
