Hardened Press-In Inserts
Series 20117 Type: HPI
Series 20117 Type HPI Inserts, offer very hard wearing threads in lighter alloys, preventing the stripping of threads where multiple installation / removal of the mating screw is likely. They are also suitable for repairing damaged threads in alloys and castings.. There is no requirement for pre- tapped holes, they simply press into a pre-drilled hole using a toggle or fly press.
