BaerCoil Wire Thread Inserts UNC No. 4 x 40 - 1.0 D (2.84 mm) - free running - 100 pcs.
BaerCoil® wire thread inserts are the perfect solution for a durable, powerful threaded connection and With the BaerCoil® wire thread inserts you create perfect, durable and powerful threaded connections. At the same time, the use of wire thread inserts allows for scrap recovery and load-bearing connections in materials with low shear strength. This is why wire thread inserts is often used in automotive, electrical engineering, medical technology, lightweight construction and aerospace.
BaerCoil® thread inserts are the perfect solution for damaged threads. They are drilled out and a new STI thread (screw thread insert) is cut for the wire thread insert. This thread is often also 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. They save weight and allow the use of smaller and shorter screw connections.
BaerCoil® thread inserts can be shortened, according to the required length, with a side cutter or similar.
