BaerCoil Wire Thread Inserts UNC 1/4 x 20 - 2.0 D (12.7 mm) - free running - 10 pcs.
BaerCoil® thread inserts are the best solution for your thread repair! With them you can create long-lasting and powerful threaded connections. The inserts also ensure that you have no waste and recycle everything. The inserts are precise and wear resistant - your screw will stay firmly in place without the thread insert slipping.
The BaerCoil® thread insert is the perfect solution for damaged threads while maintaining the same 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 are perfect for applications where a balanced distribution of forces is required. They can withstand both static and dynamic loads and help save support material.
BaerCoil® thread inserts can be shortened with a side cutter or similar, according to the length required.
