Why do CNC-machined Products need to Install Thread Insert?

In OEM Precision CNC machining, thread inserts are very common. But why are they used? What are the benefits of using thread inserts on products? When you hear "thread insert", you might think of the kind that people wear to straighten their teeth. But in the context of machining mechanical parts, a threaded insert is a threaded sleeve that is installed in a tapped hole to provide a stronger and more durable thread.

 

Why use thread inserts?

 

There are many reasons to use thread inserts in OEM CNC machining. Some of the most common benefits include:

 

Increased strength: Thread inserts are made from stronger materials than the base material of the part, such as high-strength steel or brass. This makes them more resistant to stripping and pullout, especially in applications where the threads are subjected to repeated loading and unloading.

 

Improved wear resistance: Thread inserts are also more wear-resistant than the base material, which can help to extend the life of the threads. This is especially important in applications where the threads are exposed to friction or vibration.

 

Corrosion resistance: Thread inserts can be made from corrosion-resistant materials, such as stainless steel or nickel alloy. This can help to protect the threads from rust and other forms of corrosion, especially in applications where the parts are exposed to the elements.

 

Repair of damaged threads: Thread inserts can be used to repair damaged or stripped threads. This can be a much more cost-effective solution than replacing the entire part.

 

Versatility: Thread inserts can be used in a wide variety of materials, including metals, plastics, and wood. They can also be used in a variety of applications, including automotive, aerospace, and medical devices.

 

In addition to the benefits listed above, thread inserts can also offer the following advantages:

 

Improved thread quality: Thread inserts can help to produce higher-quality threads with a cleaner finish and tighter tolerances.

 

Reduced assembly time: Thread inserts can be installed quickly and easily, which can help to reduce assembly time and costs.

 

Increased design flexibility: Thread inserts can be used to create threads in locations that would be difficult or impossible to tap, such as thin walls or blind holes.

 

Overall, thread inserts are a versatile and cost-effective way to improve the strength, durability, and wear resistance of threaded fasteners in CNC machined parts.

What are the different types of thread inserts available?

 

There are many different types of thread inserts available, each with its own unique set of features and benefits. Some of the most common types of thread inserts include:

 

Helical wire inserts: These inserts are made from a coiled wire that is inserted into the hole and then expanded to create a tight fit. Helical wire inserts are a good choice for applications where high strength and pull-out resistance are required.

 

Screw thread inserts: These inserts are made from a solid piece of metal that is threaded on the inside and outside. Screw thread inserts are a good choice for applications where a clean and finished appearance is important.

 

Self-locking inserts: These inserts feature a mechanism that prevents them from loosening due to vibration or shock. Self-locking inserts are a good choice for applications where the threads are subjected to dynamic loads.

 

 

How do I choose the right thread insert for my application?

The best way to choose the right thread insert for your application is to consult with a qualified engineer or machinist. Such us, we can help you assess your specific needs and recommend the right type of insert for the job.

 

How do I install thread inserts?

The installation process for thread inserts will vary depending on the type of insert you are using. However, the general steps are as follows:

Drill a hole in the base material. The hole should be slightly larger than the outer diameter of the insert.

Tap the hole to the correct thread size.

Insert the thread insert into the hole.

Expand the insert (if necessary) to create a tight fit.

Break off the tang (if necessary).

How much do thread inserts cost?

The cost of thread inserts will vary depending on the type of insert, the size of the insert, and the quantity you order. However, in general, thread inserts are a relatively inexpensive way to improve the performance of threaded fasteners.

 

Where can I buy thread inserts?

Thread inserts can be purchased from a variety of sources, including online retailers, industrial distributors, and specialty fastener shops. If you make the CNC machining parts with us, we will help you to buy the suitable inserts and then install them.

 

The material of the thread insert is an important factor to consider when choosing the right insert for your application. The most common materials for thread inserts include:

 

Brass: Brass is a versatile and affordable material that is often used for general-purpose applications. It is resistant to corrosion and has good strength and wear resistance.

Stainless steel: Stainless steel is a more expensive material than brass, but it is also more durable and resistant to corrosion. It is a good choice for applications where the threads will be exposed to harsh environments.

 

Steel: Steel is the strongest and most durable material for thread inserts. It is a good choice for applications where the threads will be subjected to heavy loads.

 

Aluminum: Aluminum is a lightweight material that is often used in aerospace and other applications where weight is a critical factor. It is not as strong as steel or stainless steel, but it is still a good choice for many applications.

 

Plastic: Plastic thread inserts are a good choice for applications where low cost and weight are important. They are not as strong as metal inserts, but they are still a good choice for light-duty applications.

 

The best material for your application will depend on your specific needs. Consider the following factors when making your decision:

Strength: How much load will the threads be subjected to?

Durability: Will the threads be exposed to harsh environments?

Corrosion resistance: Will the threads be exposed to moisture or chemicals?

Weight: Is weight a critical factor?

Cost: What is your budget?

Once you have considered these factors, you can narrow down your choices and select the right material for your application.

Thread inserts can be used in a wide variety of materials, including:

 

Metals: Thread inserts are most commonly used in metals, such as aluminum, steel, stainless steel, and brass. This is because metals are strong and durable, and they can withstand the forces that are applied to threaded fasteners.

Plastics: Thread inserts can also be used in plastics, such as ABS, PVC, and nylon. This is because plastics are lightweight and inexpensive, and they can be molded into complex shapes. However, plastics are not as strong as metals, so they should only be used in applications where the threads will not be subjected to heavy loads. Thread insert used in nylon.

 

Wood: Thread inserts can also be used in wood, such as oak, maple, and pine. This is because wood is a strong and versatile material that can be used in a variety of applications. However, wood is not as durable as metal, so it should only be used in applications where the threads will not be exposed to moisture or extreme temperatures. Thread insert used in maple.

In general, thread inserts are a good choice for any CNC product that requires strong, durable, and corrosion-resistant threads. Here are some specific examples of CNC products that commonly use thread inserts:

 

Automotive parts: Thread inserts are often used in automotive parts, such as engines, transmissions, and suspension systems. This is because automotive parts are subjected to a lot of stress and vibration, and thread inserts can help to prevent the threads from stripping or loosening.

 

 

Aerospace parts: Thread inserts are also commonly used in aerospace parts, such as engines, airframes, and landing gear. This is because aerospace parts need to be lightweight and strong, and thread inserts can help to achieve both of these goals.
