Brass Insert

About Brass Insert

Large brass inserts are high-strength, threaded fasteningcomponents designed for heavy-duty applications in plastics, wood, and metal,commonly used to create robust, reusable metal threads. They are typicallymanufactured from free-cutting brass (IS 319, C36000), offering excellentcorrosion resistance, durability, and high thermal conductivity for heat-setinstallations.

Key Description and Features

• Dimensions: Available in larger sizes, including heavy-duty M18-M24 diameters and lengths designed for deep embedding 
• Material: High-grade Free Cutting Brass (CZ121, C36000) is standard, sometimes featuring Nickel, Chrome, or Tin plating to enhance durability. 
• Knurling Patterns: Feature deep diamond, straight, or unidirectional knurling on the outer diameter to provide maximum pull-out resistance and torque capability within plastic or wood. 
• Types: Available as blind (closed-end) or through-threaded, as well as specialized types like expansion, press-in, or mold-in inserts. 
• Threads: Manufactured to international standards (Metric, UNC, UNF, BSP, BSW) with "Go/Not Go" gauge compliance.

Common Applications

• Industrial Machinery
• Plastic Molding
• Telecommunications & Electrical
• Architectural/Heavy Duty

Benefits

• High Performance: Resistant to vibration and stress, preventing the stripping of plastic bosses.
• Reliability: Provides superior torque resistance and long-lasting, rust-proof connections.
• Versatility: Suitable for heat-set, ultrasonic, or cold-press installation methods.
