Custom Cylindrical Metal Threaded Nut With External Gear Teeth Insulating White Plastic Sleeve

Custom Cylindrical Metal Threaded Nut with External Gear Teeth and Insulating White Plastic Sleeve – Precision Hybrid Component for Mechanical Locking & Electrical Isolation

This custom-engineered hybrid nut component combines the mechanical strength of metal with the functional versatility of engineered plastic. Featuring a cylindrical profile, the product is designed for enhanced mechanical locking, electrical insulation, and vibration damping in various industrial applications.

Key Structural Features:
• Internal Threaded Core:
At the center lies a precision-machined metal threaded hole, providing secure and stable fastening capability. The threading is cleanly cut, compatible with standard bolts or threaded rods used in mechanical assemblies.
• White Plastic Insulating Sleeve:
Surrounding the metal core is a white plastic ring that acts as both an insulator and a cushioning layer. This non-conductive component offers protection against short-circuits, absorbs vibrations, and reduces mechanical wear during repeated use.
• External Gear-Like Tooth Structure:
At the base, the nut features an evenly spaced, gear-like tooth structure made of hardened metal. These precision teeth are distributed around the circumference in a tight, uniform pattern. From the reverse side, the full circular array of teeth is clearly visible—offering robust grip and interlocking performance when mated with corresponding mechanical components.

Functional Advantages:
• Hybrid Construction: Combines the durability of metal with the functionality of plastic insulation.
• Gear Teeth Design: Enhances mechanical stability, prevents loosening, and enables rotational interlock.
• Insulation & Damping: White plastic ring improves safety and equipment longevity.
• Application Flexibility: Can serve in fastening, torque transfer, anti-slip engagement, or alignment locking mechanisms.
