It resembles a coiled spring, but instead of round cross section wire, it's made from square section
wire, set 'diamond' wise. For stripped threads, the hole is drilled and tapped to the size of the
helicoil, then it is 'screwed' in, and locked in place, usually by knocking the ends of the hole
thread with something like a centre-punch.
Hope that helpS!
