PTI - Sert Timesert is the market leader in solid inserts for thread repair.

These inserts are only completed on installation, using the usual steps to insert, Drilling, Tapping, Counter Sinking then inserting.

The Timesert is then actually finished and formed when inserted as the last three threads are then completed by cold rolling process, this final step allows the Timesert to be a permanent installation and liquid and air tight in the process.

The only real way to remove a Timesert is by drilling the insert out, this is not easy to do as the insert is designed to be Permanent.

Self Tapping Thread Insert

Self Tapping Threaded Inserts are single piece, precision turned parts with both external and internal metric threads and are manufactured from mild steel, stainless steel or brass. These inserts allow permanent threads to be produced in a wide range of components and materials.

Tough and durable due to their substantial wall thickness, their use can reduce the thread size required due to the insert's large effective shear surface. This could save material as well as reduce cost and weight. They eliminate the need for close tolerance holes required for tapping into the base material, damaged tools and low productivity - they need no special installation tool nor the time consuming process associated with installing a wire thread insert. Holes do not need to be separately tapped as the groove will cut its own thread so long as the correct diameter tolerances for the material and the insert are adhered to.

Shows the installation process

Wire inserts are made in stainless steel (X 10 Cr Ni 18-8) They are used to reinforce or repair all types of tapings. Particularly adapted for soft materials (aluminium, magnesium), wire inserts presents a high resistance to thermal (up to 425°C for a short period of time and up to 325° C without interruption), corrosive, atmospheric conditions and mechanical strain. They are used in different areas (railway, mechanics, armament, electronics, car industry, aerospace). Possible coatings: dried lubrication, zinc plating, silver plating. Wire insert can be delivered in green colour that makes the thread visible to the eye when it is inserted in aluminium tapings. Comply with the DIN 8140.

The KN-KNH inserts with 2 or 4 locking keys* that once installed lock the insert against the rotation due to torsion or vibration. The keys are placed in the proper seats by a punch or a hammer (see picture 4. Installation). Available in thin wall and heavy duty versions. Used to obtain high performance thread on light alloys, steel and cast iron or to repair worn thread.
