Brass Inserts
Brass Inserts are precision-engineered fastening components designed to provide strong, durable, and wear-resistant threads in plastic, wood, thermoplastics, and soft metals. Manufactured from high-grade brass, these inserts ensure maximum pull-out strength, excellent torque performance, and long-term reliability in demanding industrial applications.
Made using CNC machining or automatic turning processes, brass inserts offer superior dimensional accuracy and smooth thread profiles, making them ideal for high-volume production and assembly operations. Their corrosion resistance, conductivity, and mechanical stability make them the preferred choice over steel or plastic inserts in applications requiring high performance and longevity.
Brass Inserts Key Features
High Tensile Strength: Provides strong internal threads for secure fastening.
Corrosion Resistant: Brass naturally resists rust, moisture, and chemical exposure.
Excellent Thermal Conductivity: Ideal for heated plastic insertion and molding.
Precision Machined: Ensures accuracy, smooth threads, and easy installation.
Reusability: Threads do not strip easily, ensuring repeated assembly and disassembly.
Vibration Resistant: Maintains tightness and stability in vibrating environments.
Applications of Inserts
Brass inserts are widely used across industries such as:
Electronics & Electrical Goods
Automotive Components
Plastic Molding Industry
Consumer Appliances
Telecommunication Equipment
Furniture & Woodworking
3D Printing and Prototyping
They are commonly used in enclosures, switches, PCB mounts, molded parts, sockets, handles, and structural plastic assemblies.
Type of Brass Inserts
Heat-Set Inserts
Installed using heat insertion tools.
Ideal for thermoplastics like ABS, Nylon, Polycarbonate.
Ultrasonic Inserts
Inserted using ultrasonic welding machines.
Provides rapid installation and excellent grip.
Self-Tapping Inserts
Cuts its own thread during installation.
Suitable for thermoset plastics and wood.
Press-Fit / Push-In Inserts
Requires no heat or tools; pressed directly into soft plastics.
Mold-In Inserts
Placed in the mold during the injection molding process.
Delivers exceptional pull-out strength.
Threaded Inserts (Round / Hex / Knurled)
Available in round, slotted, hexagonal, and diamond knurling patterns.
