BaerCoil Wire Thread Inserts UNF No. 4 x 48 - 1.0 D (2.84 mm) -100 pcs.
BaerCoil® wire thread inserts not only ensure a long-lasting and powerful threaded connection in the thread repair, but also enable scrap recovery. The inserts also create load-bearing connections in materials with low shear strength. Thanks to their precision and wear resistance, the BaerCoil® thread inserts hold your screw firmly in place without changing the thread insert. Ideal for repairing stripped or worn threads. wire thread inserts are often used in automotive, electrical, medical, lightweight construction, and aerospace applications.
The BaerCoil® thread insert is the perfect solution for damaged threads. With the use of 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. 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.
