Technifast provide a varied range of inserts, which are frequently categorised by the method of insertion.

We have a vast range of self tapping inserts, designed to give more strength, particularly where composite materials are used. Our through tapped metric OD inserts (thread reducers / thread repair) are ideal for use on pre-tapped holes which make them suitable for application with most materials and have a standard through-tapped metric internal with metric external threads.  We also stock self tapping inserts with a high resistance to pull-out, making them ideal for use in plastics, wood and non-ferrous metals.  


Our ultrasonic or heat inserts, which are for use in thermoplastic materials and are stocked in brass.

Finally, the expansion inserts are an ideal solution when a durable thread is required, but the high pull-out resistance of a self-tapping insert is not essential.

For non-standard threaded inserts, please contact us with your requirements
