BaerCoil Wire Thread Inserts UNF 1/4 x 28 - 1.5 D (9.53 mm) 10 pcs.
BaerCoil® thread inserts are the best solution for all your repair needs! With them you can create long-lasting and powerful connections. These 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.
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 are indispensable for optimum force transmission in lightweight constructions. They ensure that both static and dynamic work loads are distributed in a balanced manner to the individual thread turns. Also, the flexibility of the thread inserts compensates for any pitch and angle errors. BaerCoil® thread inserts not only save time and money, but are also much lighter and more compact than conventional screw connections.
BaerCoil® thread inserts can be shortened, according to the required length, with a side cutter or similar.
