BaerCoil Wire Thread Inserts M 9 x 1.25 - 3.0 D (27 mm) - free running - 10 pcs.
BaerCoil® thread inserts are the perfect solution for your thread repair needs! These inserts provide a long lasting and powerful thread connection and scrap recovery.
The BaerCoil® thread insert is the perfect solution for damaged threads while maintaining nominal diameter. For thread repair with wire thread inserts, the thread is drilled out and a new STI thread (screw thread insert) is cut for the wire- thread insert. This thread is often called STI thread (STI=Screw Thread Insert). Then the BaerCoil® thread insert is screwed into the old thread and thus the workpieces are screwed on again. With BaerCoil® thread inserts, the thread produced is significantly more stable than the original thread.
BaerCoil® thread inserts ensure optimum power transmission from the bolt to the nut thread, even in lightweight constructions. Today, they are already an important component in aviation and vehicle construction.
BaerCoil® thread inserts can be shortened according to the required length with a side cutter or similar.
