White Zinc Plated Knurled Threaded Insert High Precision For Plastics

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.

Key Features

✅ 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.
