These are stainless steel and longer than the usual inserts. Just what we needed.

These worked perfectly with my elderly Heli-coil tap and driver. Just for your information, these make great thread inserts into hardwoods such as making jigs and fixtures for woodworking shops. I've been doing this for many years since I transitioned from mechanics and metal working to furniture making. These are a lifesaver and have bailed me out of many a situation when aluminum threads were stripped out etc.
