M3 Brass Threaded Insert is a fastener used to provide durable and reliable threads in softer materials such as plastic or wood. The insert of M3 Brass Threaded Insert has a nominal diameter of 5.5mm, a pitch of 0.5mm, a length of 4.5mm and a tolerance of ±0.05mm. The main function is to strengthen the threaded connection, making it strong enough to withstand repeated use without stripping or loosening. M3 represents that the internal thread diameter of the insert is 3.0mm, which is very suitable for use with screws of the same size.
M3 Brass Threaded Insert is manufactured from high-quality BSBM brass. This material is known for its excellent machinability, corrosion resistance and good thermal conductivity. The following are the main processing steps:
Material Selection and Preparation
The raw material is high-quality BSBM brass, which is corrosion-resistant and high-strength, ideal for industrial applications and can provide long-lasting performance.
Precision Machining
Brass inserts are manufactured through precision machining to ensure compliance with international standards such as JIS, ANSI, DIN and BSI. Advanced CNC machines are used during the machining process to ensure the accuracy of internal and external thread dimensions.
Surface treatment - degreasing
After machining, M3 brass threaded inserts are subjected to a degreasing surface treatment. This process removes grease and other contaminants left over from the machining stage. Degreasing ensures a clean, corrosion-resistant surface, which extends the life of the insert.
Salt spray test to test corrosion resistance
To verify the durability of the insert, a salt spray test is performed to ensure that it can maintain corrosion resistance in a salt spray environment for at least 12 hours. This test simulates harsh environments to evaluate the performance of the insert under corrosive conditions.
Main features
M3 brass threaded inserts are manufactured to strict international standards to ensure high compatibility, uniform quality and reliability in a variety of applications.
The use of high-quality brass materials makes the inserts corrosion-resistant in typical industrial and environmental conditions. Degreasing provides a clean surface, further enhancing its corrosion resistance.
The M3 internal and external design provides superior thread engagement, ensuring a secure and stable installation even in materials that are prone to wear or deformation.
The nominal length tolerance is ±0.05mm, ensuring a perfect fit during assembly. Salt spray testing for more than 12 hours demonstrates the insert’s durability in wet or salty environments, ensuring a longer service life.
Designed for easy installation, M3 Brass Threaded Inserts can be applied to a variety of substrates using a variety of techniques such as ultrasonic insertion, press fit or heat insertion, without the need for special tools.
Due to their versatility and durability, M3 Brass Threaded Inserts are used in a variety of industries and consumer sectors:

Our logistics information exchange :
When installing an M3 brass threaded insert, how can you ensure that it is secure and does not loosen?
To ensure that the M3 brass threaded insert is securely installed, appropriate installation techniques can be used, such as ultrasonic embedding or heat embedding. These methods can use the texture on the outside of the insert to tightly bond with the plastic material, thereby reducing the risk of loosening. In addition, the pressure and temperature of the insert should be controlled during the installation process to avoid damaging the base material.
Will the M3 brass threaded insert corrode in harsh environments?
The M3 brass threaded insert itself is made of high-quality brass and has good corrosion resistance. However, in particularly humid or high-salinity environments, it is recommended to choose an insert with additional surface treatment, such as nickel plating or tin plating, to increase corrosion resistance. If the insert has been degreased before use, its corrosion resistance will also be enhanced.
How to avoid thread stripping during use?
Thread stripping problems are usually caused by excessive torque or mismatch between the screw material and the insert. To avoid this:
Control the installation torque: When installing the screw, follow the recommended torque range and do not exceed the bearing capacity of the brass insert.
Choose the right screw material: Avoid using screws that are too hard and choose screw materials that are compatible with the brass insert to prevent thread damage.
Are M3 brass thread inserts suitable for high-intensity loads?
M3 brass thread inserts are suitable for medium-intensity loads, but when facing high-intensity loads or vibration, it is recommended to use larger specifications or stronger materials (such as stainless steel). If brass inserts must be used, the load can be distributed by increasing the insert length or using multiple inserts to improve overall strength.
How to choose the right length for M3 brass thread inserts?
The choice of insert length depends on the substrate thickness and the expected load. Generally, the insert length should be two-thirds to three-quarters of the substrate thickness to ensure the best connection strength and stability. Choosing an insert that is too short may cause instability, while an insert that is too long will affect the installation process.
Can M3 brass thread inserts support repeated disassembly and assembly?
M3 brass thread inserts can support limited repeated disassembly and reassembly. Because brass materials have a certain degree of flexibility and toughness, they can withstand several disassembly and reassembly. However, if the number of repeated disassembly and reassembly is too many, it may cause thread wear or damage to the base material, affecting the use effect. Therefore, if frequent disassembly and reassembly is required, it is recommended to choose a more durable insert material or add thread locker during installation.
How to achieve the best anti-loosening effect on M3 brass thread inserts?
To enhance the anti-loosening effect, you can consider the following methods:
Use anti-loosening washers: Add elastic anti-loosening washers between the screw and the insert.
Apply thread lockers: Use thread lockers (such as Loctite) and apply them to the screw threads during assembly to increase the anti-loosening effect.
Choose thread inserts with self-locking function: Some inserts are designed with self-locking threads to provide additional anti-loosening function.
What are the customization options for brass thread inserts, and how can you ensure that your specific needs are met?
M3 brass thread inserts support a variety of customization options, including size, thread type, surface treatment and material substitution. To ensure that the customized product meets your needs, you can provide the following information to CHEKSINE:
Specific size requirements: such as length, diameter and pitch.
Required materials or special alloys: such as stainless steel with higher corrosion resistance or specific copper alloys.
Special surface treatment: Select appropriate plating or protective treatment according to the application environment, such as nickel plating, tin plating, etc.
Application environment and usage requirements: Describe the usage scenario and possible load conditions so that the manufacturer can provide a more optimized customization solution.
