Threaded Brass Inserts, 6-32, Sonic Weld, Press or Solder.

Add threads to new projects as well as modify or repair existing products. If the plastic you are using can be melted with a soldering iron you can place the insert on the part you want to add threads to. Then heat the insert with a soldering iron and press in to the part as the insert melts the plastic. Try with and without pilot hole. Excess plastic can be cleaned up with a dremel tool. You can also try soldering the inserts to the surface of metals that can be soldered such as copper and brass. Add these as threaded standoffs by soldering to bare copper on you circuit boards. Just the right color for steam punk projects. This part can be pressed into some materials with the right size pilot hole. Get them here:
