BaerCoil wire thread inserts thread repair & reinforcement

Thread Inserts

When threads are frequently used or exposed to high loads, it can quickly happen that the threads strip or deform. In such cases, to avoid losing the entire component, products for thread repair or reinforcement are used. With BaerCoil thread inserts, you increase the load capacity of your threads and reliably protect them from wear. Rely on the proven quality of our thread inserts and other products from the BaerCoil range to repair or reinforce your threads in no time!

Everything you need to know about BaerCoil thread repair

Using BaerCoil wire thread inserts increases pull-out strength, ensures better load distribution, and enlarges the effective shear surface. They also protect your threads from wear and corrosion. Especially when working with materials such as magnesium or aluminium, or in environments with frequent shocks and vibrations, you can significantly improve the quality and strength of your threaded connections. And if damage has already occurred, BaerCoil thread inserts are also ideal for thread repair.

Our wire thread inserts are available in many sizes and versions to optimally cover your application. Unlike self-tapping thread inserts such as our BaerFix products, wire thread inserts cannot create their own receiving thread. You will also find suitable tools for preparing the pilot hole and thread in our range.

The wire thread insert can be screwed into the prepared thread by hand or machine. It flexibly adapts to the thread flanks and slightly elongates. Since all tools are perfectly matched, the repaired thread will have exactly the desired size.

BaerCoil thread inserts – Our range

To fully support you in thread repair and reinforcement, we offer BaerCoil thread inserts in numerous sizes, designs, and for many common thread types. Our products are available as the standard free-running type and the screw grip type with screw locking. For some thread types, we also offer the NoTang type without a tang.

Thread inserts for metric threads

For standard and fine metric threads, we offer a wide range of inserts. The free-running type is available not only in V2A stainless steel for all standard applications, but also in special materials such as bronze (for better electrical conductivity) or Inconel (for particularly high corrosion resistance). This allows us to cover application areas far beyond normal use, such as aerospace or seawater applications.

The screw grip version with additional screw locking is also available for metric threads. The polygon-shaped coils exert a clamping effect on the screw flanks and withstand frequent vibrations. These wire thread inserts are easily identified by their red colour.

A special feature is our NoTang thread inserts. These are installed without a tang, using special installation tools that engage in a notch in the wire. This not only eliminates the step of breaking off the tang, making installation more efficient, but also removes the safety risk posed by lost or jammed tangs.

Thread inserts for American threads

Of course, you can also reinforce and repair American thread types with BaerCoil wire thread inserts. We offer suitable products for both UNC coarse threads and UNF fine threads. The inserts are available in both free-running and screw grip versions in a variety of dimensions and lengths.

Thread inserts for British threads

We also stock thread inserts for British thread types, including BSW coarse threads, BSF fine threads and British Association BA threads. For these threads too, we offer the classic free-running and screw grip types, covering almost all standard applications.

We also carry a selection of wire thread inserts for the British Whitworth pipe thread, known and widely used here as G thread. This means you can also rely on high-quality BaerCoil products for thread repair and thread reinforcement in the sanitary and HVAC sector. The inserts for G threads are available in the free-running version.
