I am currently on a project where hardened helicoil inserts are being used in a quick change blind application. They are used as a wear item in the 316SS flanges and can be replaced rather than the flange. They are 1" dia. bolts and are designed for 3600 psi working pressure. You may want to phone WellMark Company at 1-800-424-8647 if this is relevant to your question.
