BaerCoil Wire Thread Inserts M 4 x 0.7 - 1.5 D (6 mm) - screw grip (screw locking) - 100 pcs.
BaerCoil® thread inserts are the best solution for your thread repair! With them you can create long-lasting and powerful threaded connections. The inserts also ensure that you have no waste and recycle everything. The inserts are precise and wear resistant - your screw will stay firmly in place without the thread insert slipping.
The BaerCoil® thread insert is the perfect solution for damaged threads. For thread repair with wire thread inserts, the thread is drilled out and a new STI thread (screw thread insert) is cut for the wire- 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 optimal force 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® screw-locking thread inserts | Type "screw grip " - All advantages at a glance
With the self-clamping "screw grip" thread inserts, your construction remains stable - no matter whether it is exposed to 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.
