BaerCoil Wire Thread Inserts UNC No. 4 x 40 - 2.0 D (5.69 mm) - free running - 100 pcs.
BaerCoil® thread inserts are made of high-quality materials wire thread inserts. BaerCoil® thread inserts provide a durable and powerful threaded 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, holding 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.
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 optimum power transmission from the bolt to the nut thread - even in lightweight constructions. Due to their flexibility, they can compensate for pitch and angle errors and thus guarantee optimum power transmission. BaerCoil® thread inserts are already important components in the aerospace and automotive industries and help to reduce carrier material and use smaller, shorter bolted joints.
BaerCoil® thread inserts can be shortened, according to the required length, with a side cutter or similar.
