Q: 1. Is the threaded connection on the bottom 5/8" ? I didn't see it listed on the product page.

Q: 2. Could the Boom Arm hold the Amaran 300c RGB LED Monolight with an Aputure Lantern 90 (3') attached to it?

A: The Impact Boom Arm (Chrome-plated, 86") at full extension is not strong enough to hold the Amaran 300c RGB LED Monolight with an Aputure Lantern 90 (3') attached. The setup is over 8 lb and the boom at full extension supports no more than 8 lb.

Q: 4. What is the difference between the Manfrotto 085B and 085BS, in regards to the boom arm only?

A: The 085BS replaces the no longer available 085B. I believe the only difference in the boom arms was the color and the length. If memory serves me correctly the 085B has a 7' silver boom and the 085BS has a 9' black boom.They are both three section arms with the same counterweight and spigot. While I've never owned the 085B I do own the 085BS and can au the stand and the boom arm are extremely sturdy and hold up very well.

Q: 5. Will this work atop a Manfrotto 5001 stand with the 124 clamp?

A: The 5001B stand is way too small to securely support a boom arm, pivot clamp, and whatever you are going to put on the end of the arm. And the top section of tubing is too thin to accept the 124 pivot clamp.I would suggest you go with a stand like the 1052BAC or similar.

Q: 6. Is it possible to remove the rotating stand mount from the boom arm?

A: The impact base boom does allow a end-user to remove the mount to be fine tune but we do not suggest doing so.

Q: 7. Will this be able to support the weight of a "Shure SM7B" (1.69 lb / 766.57 g)?

Q: 8. Im thinking about buying it to use with a Selens 75' (12.05 pounds). Does this arm will hold it?

A: The maximum load capacity of the Manfrotto 085BS Heavy-Duty Boom and Stand at full extension is 13.2 lbs (6kg) with the included 15 lbs (7kg) counterweight. If you use a larger counterweight or use the boom arm at a shorter distance (not at full extension), it can support more weight. As you state your setup weighs 12.05 lbs, it should be compatible for use with the Manfrotto 085BS Heavy-Duty Boom and Stand at full extension.

Q: 9. Does it come with a 5/8"-27 male threaded end for a microphone clip or an adapter for that?

A: No, the Impact Boom Arm would have a 5/8" stud for lighting. To allow for a microphone to fit, you can use the CAMVATE 5/8" Light Stand Head with 5/8"-27 Screw for Microphone Clip Stand, BH # CAC2950. http://bit.ly/3AlsoVd
