What does ics Compression do?

Answer 1

If your threads (small circle in middle) on your starnut separated from the flanges (metal that sticks off and bends) then you have two options. You can fix it or get a new starnut. To fix it get a welder to put and small tack weld on the edge of the threads to hold it in place. You can also get a new starnut. You either can install the new starnut above the old one or remove the old one by drilling many holes in the starnut until it is destroyed or pull up each segment of the flange until it can be removed.
