BaerCoil Wire Thread Inserts BA 4 - 3.0 D (10.8 mm) - free running - 100 pcs.
BaerCoil® wire thread inserts provide a durable and powerful threaded connection in the thread repair. The inserts also create load-bearing connections in materials with low shear strength and are precise and wear-resistant. wire thread inserts are frequently used in automotive, electrical engineering, medical technology, lightweight construction and aerospace. BaerCoil® wire thread inserts are the perfect solution for a long-lasting, powerful threaded connection and scrap recovery. They also create load-bearing connections in materials with low shear strength and are precise and wear-resistant. wire thread inserts are frequently used in automotive, electrical engineering, medical technology, lightweight constructions as well as in aerospace.
The BaerCoil® thread insert is the perfect solution for damaged threads and that at the same time 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.
