BaerCoil Thread Repair Kit M 5 x 0.8 screw grip (screw locking)
With this BaerCoil® thread repair set it is possible to repair through hole and blind-hole threads in M 5 x 0.8 while maintaining a screw-locking thread.
BaerCoil® thread inserts are the best solution for all your thread repair needs! With them you are able to make durable and strong connections. With the inserts you avoid waste in your components and can recycle them. The inserts are precise and wear resistant - your screw will stay firmly in place without the thread insert slipping out.
The BaerCoil® thread insert is the perfect solution for damaged threads without changing the nominal diameter. For the 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. 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 back together. With BaerCoil® thread inserts, the thread produced is significantly more stable than the original thread.
Our thread inserts ensure that both static and dynamic work loads are distributed evenly over the individual thread turns. In addition, the flexibility of the thread inserts compensates for possible pitch and angular errors, so that optimum force transmission from the bolt to the nut thread is achieved. Especially in lightweight constructions, BaerCoil® thread inserts help to save carrier material and to use smaller or shorter screw connections. They are already an important component in aviation and vehicle construction. They significantly save material and contribute to the conservation of resources.
For repair directly on the thread, this thread repair kit contains various auxiliary tools, such as the core drill bit, hand tap with oversize for insert thread, insertion tool, tang breaker and wire thread inserts made of stainless steel.
With the self-clamping "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-flowing" 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® screw-locking thread inserts | Type "screw grip " - All advantages at a glance
With the self-clamping "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.
