What you’re looking at is the inside mic clip portion on a Cobra 29LTD cover. The two holes the nuts are covering were striped out by someone that over tightened the sheet metal screws. The application of PC-7 Epoxy Paste solved this problem. M3 screws are the popular size that is used on most CB chassis and I wanted to maintain the same M3 size consistency throughout. The M3 nuts I’m using are stainless steel so soldering them in place is not an option. To form the hole alignment plus maintaining stability while waiting for the paste to cure (24 hours), I simply screw down the nut to the inside of the chassis. Care is taken so that the screw thread does not go beyond the nut after tightening. I have some short screws that fit perfect, but adding washers to a longer one will do. The idea is that you only need to envelope the sides of the nut. Getting any paste on the threads will make the screw difficult to remove. Once cured this paste becomes rock hard. Afterwards you can remove the screw and apply any length or matching crew. I use JB Weld on many other repairs, but it’s not strong enough for this job.
