Product Overview
Enhance the durability and reliability of your plastic assemblies with our White Zinc Plated Knurled Threaded Inserts, engineered for precision and longevity in demanding environments. These inserts combine a corrosion-resistant zinc finish with a diamond-knurled exterior to create secure, stripped-proof threads in plastic, wood, and composite materials. Ideal for automotive, electronics, and consumer goods, they ensure vibration-resistant, reusable fastening in applications where strength and aesthetics matter.
✅ White Zinc Plated Finish
Electroplated zinc coating provides superior rust and corrosion resistance, ideal for humid or mildly corrosive environments.
✅ Diamond-Knurled Exterior
Aggressive knurling bites into plastic for a non-rotational grip, preventing pull-out under dynamic loads or vibration.
✅ High-Precision Threading
CNC-machined metric or imperial threads (M3–M12) ensure flawless compatibility with screws, bolts, and studs.
✅ Optimized for Plastics
Designed for use in thermoplastics (ABS, nylon, polycarbonate) and composites—no pre-tapping required.
✅ Easy Installation
Install via heat-setting (for thermoplastics), press-fit, or ultrasonic insertion tools for rapid assembly.
✅ ROHS & REACH Compliance
Lead-free and environmentally safe, meeting global standards for consumer and industrial use.
