Key Features
- Insert Molding Ready: Designed to be placed directly into injection molds for permanent integration.
- Superior Bonding Strength: Fully encapsulated by molten plastic, providing maximum torque resistance and pull-out strength.
- No Secondary Assembly: Eliminates the need for heat staking, ultrasonic insertion, or press-fitting — reducing labor and assembly time.
- Brass Construction: 耐腐蝕性好出色, precision threads, and long service life.
- Leak-Proof & Vibration-Resistant: Ideal for applications requiring airtight or watertight seals.
- Custom Designs: Knurled, hexagonal, grooved, or stepped profiles to suit your mold and performance requirements.
