Premium Brass Threaded Inserts for Robust Fastening in Soft Materials

Elevate your fastening solutions with our high-quality Brass Threaded Inserts. Designed to provide strong, durable, and reusable metal threads in softer materials like plastics, wood, and composites, these inserts are an essential component for engineers, manufacturers, and hobbyists seeking reliable assembly and enhanced product longevity.

Product Overview

Our Brass Threaded Inserts are precision-engineered to create permanent, load-bearing threads in materials that traditionally struggle with direct screw fastening. By encapsulating a durable brass thread within the softer host material, they prevent stripping, cracking, and wear, allowing for repeated assembly and disassembly without compromising structural integrity.

Key Features & Benefits

• Superior Brass Construction: Crafted from high-grade brass, offering excellent corrosion resistance, high thermal conductivity (ideal for heat-setting), and superior strength compared to the base material.
• Durable, Reusable Threads: Creates robust internal threads that can withstand repeated assembly and disassembly without stripping, significantly extending the lifespan of your products.
• Versatile Installation Methods: Compatible with various installation techniques including heat-staking (heat-set), ultrasonic insertion, press-fitting, and cold-pressing, adapting to your specific manufacturing process.
• Enhanced Fastener Retention: Provides a strong anchor point for machine screws, bolts, and other threaded fasteners, preventing pull-out and vibration loosening.
• Wide Range of Applications: Ideal for 3D printed parts, injection-molded enclosures, woodworking projects, furniture assembly, electronic housings, and composite material applications.
• Precision Engineered: Each insert is meticulously manufactured for precise dimensions and thread conformity, ensuring a secure and reliable fit every time.
• Aesthetically Pleasing: When exposed, the natural brass finish can add a touch of quality and refinement to your product.

Common Installation Methods

Choosing the right installation method is crucial for optimal performance:

• Heat-Set (Heat Staking): The most popular method for thermoplastics. The insert is heated (e.g., with a soldering iron tip or dedicated heat-set tool) and pressed into a pilot hole. The melting plastic flows into the knurling and grooves of the insert, creating a strong, encapsulated bond upon cooling.
  • Benefits: Extremely high pull-out and torque resistance, clean finish.
• Ultrasonic Insertion: Utilizes high-frequency ultrasonic vibrations to generate localized heat, melting and reforming the plastic around the insert, similar to heat-setting but often faster and more consistent for automated processes.
  • Benefits: Very fast, strong bond, ideal for high-volume production.
• Press-Fit (Cold Pressing): Inserts are simply pressed into a slightly undersized pilot hole. Knurled, barbed, or finned designs bite into the surrounding material for retention. Best for softer plastics, wood, or when heat is not desirable.
  • Benefits: Simple, no heat required, cost-effective for lower volumes.
• Screw-In / Self-Tapping: Designed with external cutting threads and often a lead-in pilot, these inserts are screwed directly into a pilot hole, creating their own threads in the base material.
  • Benefits: Easy manual installation, good for wood, particleboard, and some harder plastics.
