· Product Overview
These Knurled Brass Insert Nuts are high-precision fasteners designed for creating durable, threaded connections in plastic, wood, and composite materials. Crafted from premium brass with intricate knurling, they offer exceptional torque resistance, pull-out strength, and corrosion resistance. Ideal for injection molding, assembly, and repair applications, these inserts ensure reliable, long-lasting threaded joints.
· Core Specifications
- Material: High-Purity Brass (CuZn39Pb3 or custom brass alloys for enhanced performance).
- Process Standard: Utilizes Precision CNC Turning + Knurling process. Thread accuracy meets ISO Metric Thread Standard (Class 6H), knurling depth is controlled within ±0.02mm, and dimensional tolerance is ±0.03mm. All inserts undergo pull-out force testing (minimum 150N for M3 size) and thread integrity inspection.
· Application Scenarios
- Plastic Injection Molding: Inserts for consumer electronics casings, automotive plastic components, and appliance housings.
- 3D Printing & Prototyping: Threaded inserts for 3D printed parts (ABS, PLA, nylon) to add durable threads.
- Furniture & Woodworking: Secure connections for wooden furniture, cabinetry, and decorative fixtures.
- Electrical & Electronics: Inserts for terminal blocks, switchgear, and wiring harness components.
· Production Process Introduction
- Material Preparation: Select brass bar stock and conduct chemical composition analysis to ensure purity.
- Precision CNC Turning: Shape the insert blanks with CNC lathes, forming outer dimensions, threads, and preliminary features.
- Knurling Operation: Add precision knurling to the outer surface for enhanced grip in host materials.
- Thread Cutting (if needed): Machine internal threads to exact specifications (Metric, Imperial, or custom threads).
- Quality Inspection: Perform dimensional measurement (thread gauge, micrometers), pull-out force testing, and visual inspection for knurling integrity.
· Packaging and Shipping Methods
- Packaging: Inserts are packed in anti-static plastic tubes or bags, then placed in sturdy cardboard boxes. Custom packaging (labeling, branding, or bulk packaging) is available for large orders.
- Shipping: Supports International Express (DHL, FedEx, UPS), Air Freight, and Sea Freight. Orders over 10,000 pieces qualify for discounted shipping rates, and tracking information is provided for all shipments.
