Threaded inserts Baer

We offer Baer threaded inserts. In the Slovak Republic we were pioneers of Baer threaded inserts technology.

The BaerCoil® system makes it possible to significantly increase the strength of threaded joints. Application of BaerCoil inserts is not time-consuming or different products and it is easy to learn. It offers designers new possibilities in the design of threaded joints. They can achieve comparable threaded joint strength, with fewer threads and smaller bolt sizes. Reducing their length can also save material on the part itself. A great advantage is the possibility to repair threads directly from hand when using a screw cutting tap.

Threaded inserts made of steel wire are threaded into a thread that was previously formed with a special cutting tap. This technology can be used not only in production but also in repairing torn threads. In addition, BaerCoil® also offers thread-reinforcing technology (forming tap). In combination with threaded inserts, we can achieve maximum increase in the strength of the threaded joint. However, the forming tap can only be used in production, not in repairs, which are usually done by hand.

Metric and inch threads

Thread inserts are designed to repair damaged threads or to armour new threads, especially in aluminium alloys. Repair and armouring are not time consuming. We achieve lifetime durability of repaired, resp. armoured thread. For each thread size, we supply a special HSS tap, assembly tool and 5-10 pcs of inserts, which can also be ordered.

Quick repair of spark plug threads

Moreover, when repairing the spark plug thread, it is not necessary to drill the damaged thread. This operation, along with the thread cutting for the Recoil insert, is carried out by a special reamer tap. As a result, the position of the repaired thread axis does not change, which is particularly important for spark plugs. The whole repair takes about 15-20 min. A typical repair, if possible, would take much longer.

We offer you a repair right at your place

Repair of threads to the original size while increasing the strength of the screw joint up to 170 %!!!
