Product Overview
Revolutionize your plastic part manufacturing with our Pre-Embedded Stainless Steel Metric Nuts, designed for seamless integration into injection-molded components. These precision-engineered nuts feature a through-hole design and are pre-embedded during molding to create robust, corrosion-resistant threaded connections in plastic assemblies. Ideal for automotive, electronics, and industrial equipment, they ensure durability, vibration resistance, and long-term reliability in demanding environments.
✅ Pre-Embedded Injection Molding Design
Specially engineered for integration into plastic parts during molding, ensuring a permanent, stripped-proof bond between metal and polymer.
✅ Stainless Steel Construction
Made from 304/316 stainless steel for exceptional corrosion resistance, strength, and performance in extreme temperatures, chemicals, or outdoor conditions.
✅ Metric Through-Hole Threading
Precision M3–M12 metric threads allow bolts to pass completely through, enabling secure fastening in multi-material assemblies.
✅ Knurled or Flanged Exterior
Textured surfaces (knurled, ribbed, or hexagonal flanges) grip the plastic matrix, preventing rotation or pull-out under load.
✅ High-Volume Manufacturing Ready
Optimized for automated injection molding processes, reducing assembly time and labor costs for mass production.
✅ ROHS & REACH Compliance
Free from hazardous substances, meeting global safety and environmental standards for consumer and industrial use.
