Quote: How many threaded holes were done with Helicoils out of the box? Lore in my biz says that everything was helicoiled. Up until 5 years ago NOTHING was helicoiled on a sub. Every hole that was damaged was welded up redrilled and threaded. The last 15years I was there I was promoted to the engineering division and wrote paperwork to accomplish new installations or repairs. The last 5 yrs ago Navsea has allowed helicoils to be used but only on non subsafe components and only on certain items. It is still preferable if you have time to weld,drill& rethread you do that in lieu of helicoils.
