L3020 Series Thread Inserts

The advantages:

Steel thread provides high degree of re-usability
Eliminates tapping operations
High pull-out resistance
Installed into plain cored hole
High mechanical strength enables use of reduced diameter fasteners
The threaded insert L3020 with cutting slot is a self-tapping
fastener for the creation of wear-free, vibration resistant
screw joints with high loading capacity in materials with low shearing strength.

Installation:

The insert is installed using traditional tapping principles.
Installation can be carried out using a hand tool (for Iow volumes),
a tapping head attachment for a pillar drill, a standard tapping machine or fully automatic installation equipment.

How to identify threading inserts?

Identifying threading inserts requires understanding their characteristics, types, and applications. Here are some steps and tips to help you identify threading inserts:

1. Understand the types of threading inserts:

Threading Inserts: These inserts are typically used to cut internal or external threads. They come in a variety of shapes and sizes, including:

ISO Inserts: Commonly used for metric threads.

UNC/UNF Inserts: For use with Unified National Coarse/Fine threads.

NPT Insert: For use with National Pipe Tapered Threads.

2. Check the insertion shape:

Geometry: Threading inserts can have different geometries, such as triangular, square or round. The geometry indicates the type of threading they are designed for.

Chipbreaker: Look for specific chipbreaker designs that can help identify the insert’s intended use.

3. Check the mark:

Most threaded inserts have markings or codes to indicate their specification. These can include:

Manufacturer Code: This can help you identify the brand and specific product line.

Insert Size and Shape: Look for numbers or letters that represent the insert size and shape.

Material Type: Some inserts may have a marking identifying the material (e.g., Carbide, High Speed Steel).

4.Material composition:

Identify the material of the blade. Common materials include:

Carbide: hard and wear-resistant, suitable for high-speed machining.

High Speed Steel (HSS): More flexible and can be used in slow speed applications.

5. Consult the manufacturer’s catalog:

If you have an insert with markings, consult the manufacturer’s catalog or website. Most manufacturers will provide detailed specifications and identification guides for their products.

6. Use thread gauge:

If you are unsure of the thread type, use a thread gauge to measure the pitch and diameter. This can help you match the insert to the correct thread application.

7. Consider applications:

Determine what the insert will be used for. Different inserts are designed for specific materials and threading operations (for example, fine threads vs. coarse threads).

8. Seek expert advice:

If you are still unsure, consult a tool specialist or machinist who has experience with threading inserts. They can provide insight based on their expertise.

Identifying a threading insert requires knowing its type, examining its physical characteristics, and consulting relevant resources. By following these steps, you can accurately identify the threading insert you are using.
