BaerCoil Wire Thread Inserts M 3 x 0.5 - 1.5 D (4.5 mm) - free running - Bronze - 100 pcs.
BaerCoil® thread inserts are the perfect solution for your thread repair needs! These inserts provide a durable and powerful thread connection and scrap recovery.
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. Often this thread is also called STI thread (STI=Screw Thread Insert).
BaerCoil® thread inserts are essential for optimal power 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.
