Product Description: Knurled Brass Insert Nuts
Product Overview
Our knurled brass insert nuts are precision-engineered fasteners designed for secure, permanent installation in plastic, composite, or resin components. Crafted from high-quality brass and featuring a knurled outer surface, these inserts provide exceptional torque resistance and pull-out strength, making them ideal for injection molding, 3D printing, and assembly applications where reliable threaded connections are essential.
Key Features
🔹 Premium Brass Material
- Made from high-grade C3604 brass for excellent electrical conductivity, corrosion resistance, and thermal stability
- Brass construction ensures long-term durability, resistance to rust, and compatibility with a wide range of mating screws
🔹 Knurled Design for Maximum Grip
- Diamond/straight knurled outer surface creates a mechanical interlock with surrounding plastic or resin, preventing rotation and pull-out under load
- Available in various knurl patterns and sizes to optimize retention in different base materials
- Ensures secure installation even under high vibration or mechanical stress
🔹 Versatile Installation Options
- Compatible with heat insertion, ultrasonic insertion, or mold-in installation methods
- Precision-machined internal threads (metric or imperial) guarantee smooth, consistent screw engagement
- Flanged and non-flanged designs available to suit different assembly requirements and load distributions
🔹 Wide Application Range
- 3D printed components and rapid prototyping
- Injection molded plastic parts (consumer electronics, automotive interiors)
- Medical devices and precision instruments
- Electronic enclosures and consumer appliances
