M3 X 4 mm Brass Heat Set Threaded Round Insert Nut-25 Pcs.

It sounds like you need information on a specific hardware item, the M3 x 4 mm brass heat set threaded round insert nut, typically used for creating threaded connections in 3D printed parts or soft materials. Here are some details about this type of insert nut:

Description

• Material: Brass
• Thread Size: M3 (metric 3 mm)
• Length: 4 mm
• Shape: Round
• Quantity: 25 pieces

Features

1. Heat Set Installation: These inserts are designed to be installed by heating them up and then pressing them into a hole. As they cool down, they form a strong bond with the surrounding material.
2. Strong Threads: Provides durable and reusable threads in materials like plastic, wood, or soft metals.
3. Corrosion Resistance: Brass offers good corrosion resistance, making it suitable for a wide range of environments.

Applications

• 3D Printed Parts: Ideal for adding threaded connections to 3D printed parts, allowing for screws to be securely fastened and removed multiple times.
• Woodworking: Can be used in woodworking projects to add threaded holes in soft or medium density wood.
• Prototyping and Small-Scale Manufacturing: Useful in various prototyping applications where durable and precise threads are required.

Installation Instructions

1. Prepare the Hole: Drill a hole slightly smaller than the outer diameter of the insert.
2. Heat the Insert: Use a soldering iron or a similar heating tool to heat the insert.
3. Insert and Press: Once the insert is heated, press it into the pre-drilled hole.
4. Cool Down: Allow the insert to cool down, ensuring it is firmly set into the material.

Install:

When the threaded insert is up to temperature (should only take a few seconds) apply the insert to the appropriate hold. Apply a very little amount of pressure and the insert will melt the plastic in the hole and allow the insert to be set in place. The plastic will flow around the knurls of the insert. Be sure to align the insert squarely and flush to the plastic surface. Remove the soldering iron when it is in place.

Assemble:

After a few moments, the threaded insert will be ‘set’ within the plastic. The threaded insert is ready to receive the screw’s threads and the parts can be assembled.

Feature:

1. Heat-Set is designed specifically for notch-sensitive plastics
2. Expansion-Sets offer simple press-in installation
3. Flow-Sert is a blind insert for installation during the moulding process
4. Brass Material Can Resist Heat.
5. Not Easy to Rust, Strong Corrosion Resistance.
6. Very high pull-out and torque resistance.
7. Can be installed by ultrasonic or Heat into thread tapered hole, or moulded in during injection.
8. No need to counterbore or countersink the boss hole since the insert has guide pilot.
9. Used on the injection moulding for tightly fixing.
