Ultimate Brass Threaded Inserts: Create Robust, Reusable Threads in Plastic & Wood

Product Overview

Tired of stripped threads in your plastic enclosures, 3D printed parts, or wooden projects? Our premium Brass Threaded Inserts are the ultimate solution for creating durable, high-strength, and repeatedly reusable fastening points. Engineered for superior performance, these inserts are designed to be easily embedded into a variety of soft materials, providing a robust metal thread that can withstand repeated assembly and disassembly.

Crafted from high-quality brass, these inserts offer an excellent balance of strength, corrosion resistance, and thermal conductivity, making them ideal for heat-setting, ultrasonic, or press-fit applications. Upgrade your designs with reliable fastening points that truly last!

Key Features & Benefits

• Premium Brass Construction:
  • Durability: Provides a strong, wear-resistant thread that significantly outlasts direct threading into plastic or wood.
  • Corrosion Resistance: Excellent resistance to rust and oxidation, suitable for various environments.
  • Optimal Thermal Conductivity: Ideal for heat-setting applications, ensuring efficient heat transfer for clean, secure embedding without damaging the surrounding material.
  • Non-Magnetic: Suitable for applications where magnetic interference is a concern.
• Superior Grip Design:
  • Aggressive Knurling & Barbs: Expertly designed external patterns maximize contact area and mechanical interlock with the host material.
  • High Pull-out & Torque Resistance: Prevents the insert from rotating or pulling out under stress, ensuring a secure and lasting connection.
• Precision Machined Internal Threads:
  • Smooth & Accurate: Ensures easy and reliable screw engagement, minimizing the risk of cross-threading.
  • Standard Metric & Imperial Sizes: Available in a wide range to accommodate common fasteners.
• Versatile Installation Methods:
  • Heat-Setting: Easily embedded using a soldering iron, hot air gun, or specialized heat-staking machine.
  • Ultrasonic Installation: Rapid and efficient for high-volume manufacturing.
  • Press-Fit: Suitable for softer materials or specific design requirements.
  • Molded-In: Can be integrated directly into injection molding processes for maximum strength.
• Enhanced Maintainability:
  • Reusable Fastening: Allows for repeated assembly and disassembly without degrading the thread, perfect for prototyping, repairs, and service access.
  • Professional Finish: Provides a clean, factory-quality appearance to your products.

Common Applications

• 3D Printed Parts: Essential for adding robust threads to PLA, ABS, PETG, Nylon, and other 3D printing filaments.
• Injection Molded Enclosures: Creates durable screw mounts for electronics, consumer goods, and industrial housings.
• Woodworking & Furniture: Reinforces joints and allows for strong, removable connections in wood, MDF, and particleboard.
• Prototyping: Accelerates development cycles by enabling quick modifications and reliable testing.
• Electronics Housings: Securely fasten PCBs, covers, and components.
• Automotive & Marine Components: Provides reliable fastening points in plastic and composite parts.
• DIY Projects & Robotics: Adds professional-grade thread integrity to hobbyist creations.

Technical Specifications (Example)

Please note that exact specifications will vary by specific insert type (e.g., straight, tapered) and size.

• Material: C36000 Free-Machining Brass (Standard)
• Internal Thread Type: Metric (e.g., M2, M2.5, M3, M4, M5, M6, M8) or Imperial (e.g., #4-40, #6-32, #8-32, 1/4-20)
• Outer Diameter (OD): Varies by thread size (e.g., M3 inserts typically have an OD between 4.2mm - 5.5mm)
• Length (L): Varies by thread size (e.g., 3mm, 4mm, 5mm, 6mm, 8mm, 10mm)
• Installation Method Compatibility: Heat-Set, Ultrasonic, Press-Fit, Molded-In
• Operating Temperature Range: -40°C to +150°C (Host material dependent)
• Recommended Hole Size: Specific to each insert size and host material density (Refer to product datasheet for precise recommendations)
• Typical Pull-out Strength: Varies significantly by host material, hole size, and installation quality, but generally superior to self-tapping screws.
• Typical Torque Resistance: Excellent, preventing insert rotation during screw tightening.

Installation Guide (Heat-Set Method)

1. Prepare Hole: Drill or mold a hole in your host material slightly smaller than the insert's outer diameter. (Refer to the specific insert's datasheet for recommended hole sizes).
2. Heat Tool: Use a standard soldering iron with a flat tip, a heat-staking tool, or a specialized insert tip, heated to the appropriate temperature for your plastic (e.g., 200-250°C for PLA, 250-300°C for ABS).
3. Position Insert: Place the insert onto the tip of the heated tool, ensuring it's straight.
4. Embed: Gently press the heated insert into the pre-drilled/molded hole. The plastic will melt, allowing the insert to sink in smoothly. Apply even, steady pressure until the insert is flush or at the desired depth.
5. Cool: Allow the plastic to cool and solidify around the insert. This creates a strong, permanent bond.
6. Fasten: Once cooled, you can confidently fasten your components with a machine screw.
