[HELP] Need to place nut inside round tube

[marlonkaye]

Hi friends.

Please watch this video

The video shows an insert nut that's specially made for that particular purpose -- inserting into steel tubes.

I ran out of that insert nut and was wondering if anyone can help me improvise using an ordinary M6 nut. My round steel tube would be 3/4 or 7/8".

I suppose the nut should be welded to something that would fit snugly inside the steel tube.

Thank you for your time.
