Tungsten Carbide Rod with Internal Thread and Spherical Head

Product Description

Tungsten Carbide Rod with Internal Thread and External Spherical Head

The Tungsten Carbide Internal Thread External Spherical Head Rod is a high-hardness, wear-resistant precision component made from premium tungsten carbide (WC). It offers exceptional mechanical properties and corrosion resistance. Featuring an internal thread design and an external spherical head structure, this product is ideal for high-precision transmission, connection, and positioning applications. It is widely used in machining, mold manufacturing, oil drilling, medical devices, and high-end industrial equipment.

Key Features:

1. Superior Wear Resistance
• Made from high-purity tungsten carbide with a hardness of ≥HRA90, significantly outperforming standard alloy steel in durability.
2. High-Precision Machining
• Internal threads are CNC-machined with tight tolerances (±0.01mm) for precise mating with matching components.
• The external spherical head is polished or ground to ensure minimal roundness error, enabling smooth rotation and swiveling.
3. Excellent Corrosion Resistance
• Resistant to acids, alkalis, and oxidation, making it suitable for humid, high-temperature, or chemically corrosive environments.
4. Versatile Structural Design
• Internal Thread: Supports standard metric/imperial threads (e.g., M6, M8, 1/4"-20) and can be customized for special thread requirements.
• External Spherical Head: Available in various diameters (Φ5mm–Φ20mm, customizable) for flexible multi-angle connections or transmissions.
5. High Strength & Rigidity
• Withstands heavy loads and impact forces, making it suitable for heavy machinery or high-vibration conditions.
