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.
If you have damaged threads, the BaerCoil® thread insert is the perfect solution - with the same nominal diameter! By reaming and inserting a new EC thread, your old thread becomes strong and stable again. With the BaerCoil® thread insert your manufactured thread will be significantly stronger than the original thread!
BaerCoil® thread inserts ensure optimum power transmission from the bolt to the nut thread, even in lightweight constructions. Today, they are already an important component in aviation and vehicle construction. They save weight and allow the use of smaller and shorter screw connections.
BaerCoil® screw-locking thread inserts | Type "screw grip " - All advantages at a glance
With the self-clamping "screw grip" thread inserts, your construction will remain stable - regardless of shocks, constant vibrations or movements. The screw-locking BaerCoil® thread inserts complement the properties of the "free running" connection and have a clamping effect on the flanks of the screwed-in screw due to their polygonally shaped windings. Please use only screws of a higher strength class for this purpose, as an elastically resilient frictional connection is created. The clamping torques are comparable with the specifications in DIN 267 Part 15 and ISO 2320. Please note that special insertion tools with reduced diameters are required for screw grip inserts.
BaerCoil® thread inserts can be shortened if necessary, according to the required length, with a side cutter or similar. It should be noted that the thread inserts with screw locking have a polygonal winding approximately in the middle of the insert. This must not be removed when shortening in order to maintain the screw locking effect.
