Threaded inserts from norelem: Quality and versatility for the highest demands
A threaded insert is an indispensable element in modern machining and repair technology. They create resilient and durable threads in materials that do not provide the necessary stability for cutting threads. Typical materials for which they are used include plastics, light metals and wood.
A major advantage is the simple and quick installation, which can often be carried out without special tools. This makes threaded inserts not only the first choice when designing new products, they are also used to repair damaged tapped holes.
Threaded inserts not only offer a solution for producing threads in soft or brittle materials, but are also essential for the repair and maintenance of damaged tapped holes. Instead of replacing a complete component, the function of the part can be restored by inserting a threaded insert. This considerably extends the service life of the product.
No wonder that threaded inserts are used in many sectors. In the automotive industry, these standard parts are often used in light metal components. Here they create durable threads that can withstand high loads.
Threaded inserts can minimise wear and facilitate maintenance on machines that are exposed to high loads. They ensure stable connections in the plastic housings of electronic devices without damaging the housing material. In constructions made of wood or composite materials, the inserts help to ensure strong fastenings.
Increased wear and corrosion resistance - advantages of threaded inserts
Threaded inserts offer numerous advantages that make them an indispensable component in production and repair. The following advantages are particularly worth emphasising:
- Long-term cost savings: The inserts help to save costs in the long term by reducing maintenance costs and extending the service life of components. A defective thread can be repaired quickly and easily without having to replace the entire component.
- Extended service life through increased wear resistance: Threads are much more durable due to the use of robust materials such as stainless steel and steel. This is particularly important in high-stress areas where wear and material fatigue frequently occur.
- Versatility in application: These standard parts are suitable for use in various materials, including plastics, light metals and wood. They provide sturdy threads in materials that would otherwise not be able to sustain durable threads.
- Easy installation: Installation is simple and usually requires only a few tools. This means that a threaded insert can be quickly integrated into existing structures or used for repairs. This saves time and effort.
- Repair of damaged threads: Threaded inserts are an excellent solution for repairing damaged threads. Instead of completely replacing a component, the damaged thread is replaced and restored by a threaded insert. Thus the functionality and service life of the component is ensured.
- Use in areas subject to heavy loads: Due to the high load-bearing capacity and durability, threaded inserts are ideal for areas subject to heavy loads. Here they ensure durable, corrosion-resistant and reliable connections.
These advantages make the inserts a valuable investment for both production and maintenance.
Product selection at norelem
Various types of threaded inserts are available from norelem to meet different requirements and areas of application. Here is a brief overview of the individual versions:
The "self-tapping threaded inserts with cutting slot" have a slot which cuts the thread as they are inserted. This ensures a precise fit and robust connection, especially in materials such as plastics or soft metals. Self-tapping threaded insert with cutting slot offer a simple and effective solution if no pre-tapped thread is available.
In some materials, the cutting slot area of the inserts deflect slightly inwards. This results in a screw locking effect. If this is not desired, we recommend the model with a cutting bores.
"Self-tapping threaded inserts with cutting bores" have three thread cutting bores. These cut a thread into the material as they are screwed in. The bores improve thread formation and increase the stability of the cut thread.
Self-tapping inserts with cutting bores are also suitable for materials with low shear strength. These can be brass, bronze, cast iron, aluminium or plastic.
However, these inserts are particularly suitable for materials that are especially difficult to machine. The thick wall of the insert absorbs more force during cutting. This force is then distributed over the three cutting bores.
Reinforced threaded inserts offer additional stability and resilience. They are particularly useful in heavily used or stressed areas. They significantly improve the service life and reliability of the threaded connection.
The inserts are available in steel or stainless steel to meet the requirements of demanding applications. Reinforced threaded inserts enable the reuse of tapped holes that have been stripped out, damaged or seized. The threaded inserts are secured with wedges to prevent rotation due to vibrations or torsion.
Solid body threaded inserts are characterised by their universal structure. They are ideal for applications where a particularly strong and durable connection is required. They are used where a tapped hole that has been drilled too large needs to be repaired.
Alternatively, they can be used where hole pitches have not been maintained and need to be redrilled. The inserts therefore offer an excellent solution for heavy mechanical engineering applications or other areas of use.
Threaded inserts with self-locking internal thread are, as the name suggests, provided with a self-locking internal thread. This prevents the screw from loosening due to vibrations or other influences. An insert with self-locking internal thread ensures a secure connection. This is particularly advantageous in dynamic or mobile applications.
This insert is also available with reinforced internal threads. This variant combines the advantages of a self-locking internal thread with a reinforced structure. The reinforced insert provides additional stability and strength. They are ideal for particularly stressed connections where maximum safety and durability are required.
In addition to the various versions, there is also the HeliCoil threaded insert set. These inserts are special because they create a heavy-duty internal thread by inserting a spiral spring. In addition to these different types, the norelem range also includes threaded insert accessories such as:
- Repair kits
- Thrust pads
- Assembly tools
- Assembly tool for reinforced threaded inserts
- Assembly tools for solid-body threaded inserts
- Assembly tools for self-tapping threaded inserts
