BaerCoil Wire Thread Inserts M 12 x 1.75 - 2.0 D (24 mm) - free running - Bronze - 100 pcs.
BaerCoil® wire thread inserts provide a long-lasting and powerful thread connection and scrap recovery 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 are commonly used in automotive, electrical, medical, lightweight construction, and aerospace applications.
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 force transmission from the bolt to the nut thread. The flexibility of the thread inserts compensates for any pitch and angular errors so that the loads are distributed evenly over the individual thread turns. BaerCoil® thread inserts are ideal for lightweight constructions, as they reduce the carrier material and enable smaller or shorter screw connections. 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.
