<<I need to attach a metal piece into brass stock. This tool will be heated with a key easing tool. How can I attach it securely and have it hold even when heated? It will be stressed and needs to be a strong bond. >> Greetings, Drill the correct size hole for a very tight fit in the brass stock while the stock is extremely hot, then insert the cold metal piece and allow the shrinkage to tighten the joint. There are also some "Thread-locker" compounds that hold up to 500 degrees, I think. REgards, Ed Foote
