Premium Brass Threaded Inserts - Robust & Reliable Fastening Solutions

Elevate the durability and longevity of your products with our precision-engineered Brass Threaded Inserts. Designed to create strong, reusable metal threads in softer materials, these inserts are the ultimate solution for enhancing product integrity and facilitating reliable assembly and disassembly. Say goodbye to stripped threads and unreliable connections.

Why Choose Brass Inserts?

Brass inserts are a superior alternative to self-tapping screws or molded-in threads in applications requiring frequent assembly, high pull-out resistance, or excellent torque-out strength. Their unique properties make them indispensable across various industries.

Key Features & Benefits:

• High-Quality Brass Construction:
  • Machined from premium C36000 (Free-Machining Brass) or equivalent brass alloy.
  • Offers excellent corrosion resistance, particularly against oxidation and moisture.
  • Provides high thermal and electrical conductivity, making them suitable for electronic applications.
  • Aesthetic appeal, especially when visible.
• Superior Thread Strength & Durability:
  • Creates robust, metal-to-metal thread engagement that significantly outperforms direct fastening into plastic or wood.
  • Designed for repeated assembly and disassembly without stripping or degrading the host material, ensuring a longer lifespan for your products.
• Enhanced Pull-Out & Torque-Out Resistance:
  • Features advanced knurling patterns (e.g., straight, diagonal, unidirectional) and specialized grooves that lock the insert securely into the parent material.
  • Provides exceptional resistance to both axial pull-out forces and rotational torque, even in high-vibration environments.
• Versatile Application Compatibility:
  • Perfect for a wide range of materials including thermoplastics (ABS, PC, PP, Nylon), thermosets, various woods, composites, and 3D-printed parts (PLA, PETG, ABS).
  • Ideal for injection-molded parts where strong, reusable threads are essential.
• Multiple Installation Methods:
  • Compatible with a variety of efficient installation techniques, including heat-staking, ultrasonic welding, press-fitting, cold-pressing, and molded-in applications.
  • Offers flexibility to integrate seamlessly into your manufacturing process.

Common Applications:

Our Brass Threaded Inserts are vital components in numerous industries and products, including:

• Electronics Enclosures & Casings: PCs, routers, smart devices, PCB standoffs.
• Automotive Components: Interior trim, sensor housings, dashboard elements.
• Medical Devices: Diagnostic equipment, portable instruments, housing assemblies.
• Consumer Goods: Appliances, power tools, sporting equipment.
• Robotics & Automation: Actuator mounts, sensor brackets, structural connections.
• Furniture & Cabinetry: Knock-down fittings, adjustable feet, hardware attachment.
• 3D Printed Parts: Adding professional, robust threads to prototypes and end-use parts.

Installation Methods Explained:

Choosing the right installation method is crucial for optimal performance. Our inserts are designed for versatility:

• Heat-Staking / Ultrasonic Installation:

  • Ideal for: Thermoplastics.
  • Process: The insert is heated (either externally or by ultrasonic vibration) and pressed into a pre-drilled or molded hole. The melted plastic flows into the knurls and grooves, encapsulating the insert and creating a strong, permanent bond upon cooling.
  • Benefits: High pull-out and torque-out values, fast cycle times.

• Press-Fit / Cold Press Installation:

  • Ideal for: Thermosets, harder plastics, wood, or when heat is not desired.
  • Process: The insert is pressed into a slightly undersized hole. The knurling creates an interference fit, securing the insert through friction and material displacement.
  • Benefits: Simple, no special equipment needed beyond a press.

• Molded-In Installation:

  • Ideal for: High-volume injection molding.
  • Process: Inserts are placed into the mold cavity before the plastic is injected, becoming an integral part of the component as it cools.
  • Benefits: Highest pull-out and torque-out resistance, strongest possible connection.

• Self-Tapping Installation:

  • Ideal for: Softer plastics and some woods where speed is critical and slightly lower performance is acceptable.
  • Process: Some specialized brass inserts feature cutting threads that tap their own thread as they are screwed into a pilot hole.
  • Benefits: Eliminates pre-drilling for some applications, quick installation.

Technical Specifications (Typical):

• Material: C36000 Brass (Free-Machining Brass) or equivalent, RoHS compliant.
• Thread Sizes: Available in a comprehensive range, including:
  • Metric: M2, M2.5, M3, M4, M5, M6, M8
  • Imperial: #2-56, #4-40, #6-32, #8-32, #10-24, 1/4-20
• Lengths: Various lengths available, typically from 3mm to 20mm.
• Knurling Patterns: Straight, Diagonal, Unidirectional (matched to specific torque/pull-out requirements).
• Head Types: Flanged (for flush mounting and increased bearing surface), Blind (for sealed applications), Through-Hole.
• Tolerance: Manufactured to exacting ISO 2768-m standards for precise fit.
• Operating Temperature: Suitable for a wide range of temperatures, limited by the host material's properties.
