BaerCoil® wire thread inserts provide a long-lasting and powerful connection in the thread repair. The inserts also create load-bearing connections in materials with low shear strength. thread inserts are precise and wear-resistant and hold your screw firmly in place without changing the thread insert. Ideal for repairing stripped or worn threads. wire thread inserts is commonly found in automotive, electrical, medical, lightweight construction and aerospace applications.
For thread repair with wire thread inserts, the thread is drilled out and a new STI thread (screw thread insert) for the wire thread insert is cut. This thread is often also called STI thread (STI=Screw Thread Insert).
BaerCoil® thread inserts ensure that both static and dynamic work loads are distributed evenly over the individual thread turns. Also, the flexibility of the thread inserts compensates for any pitch and angular errors, so that optimum force transmission from the bolt to the nut thread is achieved.
BaerCoil® thread inserts can be shortened according to the required length with a side cutter or similar.
