Grade 4.8 Hollow Lead Screw External Threaded Hollow Rod For Construction Electronic

External threaded hollow lead screws designed for aluminum-steel connections in construction electronics. These full-threaded hollow rods combine structural integrity with functional integration through their unique hollow channel design.

This product is a Hollow Full-Threaded Rod (also known as Full-Threaded Hollow Lead Screw or Hollow External Threaded Rod), featuring a comprehensive "full external thread wrapping + hollow through-channel" design:

• External Threads: High-precision threads machined along the entire length, enabling full-section compatibility with nuts and internally threaded connectors for adjustable positioning
• Hollow Channel: Internal through-cavity supports cable routing or weight-reduction design, achieving dual value of "structural connection + functional integration"

• Dual Attributes: "Full Thread + Hollow" - Full threads enable full-section adjustable connections (e.g., stepless height adjustment). The hollow design integrates functional channels (reducing external piping), weighing 30%-50% less than solid rods
• Multi-Standard Compatibility - Supports dual systems: metric threads (structural connection) + pipe threads (fluid connection). Materials range from economical (carbon steel) to high-end (316L), covering civil, industrial, and military applications
• Thread Precision Guarantee - Utilizes thread rolling process for uniform threads. Pitch deviation ≤±0.02mm, with 100% go/no-go gauge inspection, ensuring compatibility with imported/domestic threads and preventing stripping

• Customization: Supports reducing adapters (e.g., G1/2" to M20) and variable wall thickness design (local thickening for strength)
• Quality: Each batch is inspected to agreed standards. Third-party inspection is supported
