BaerCoil Wire Thread Inserts M 2.5 x 0.45 - 1.0 D (2.5 mm) - screw grip (screw locking) - 100 pcs.
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 are commonly found 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 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® screw-locking thread inserts | Type "screw grip " - All advantages at a glance
With the self-locking "screw grip" thread inserts, your construction remains 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.
