Helicoil Shrinkage at Installation

Just as a matter of curiousity.....I was installing helicoils (in a new billet AL flywheel for the pressure plate bolts) and had to run one helicoil all the way through and out the back side, because I missed a burr in the threaded hole and the helicoil was not sitting in the hole right.

It was interesting to see just how much the helicoil shrunk from its original form. (I did have to turn it a bit harder than normal to get it past the burr so that may be part of this change.)
