External Threaded Hollow Lead Screw For Construction Electronic

External threaded hollow lead screws suit Al-steel connections in construction electronics

I,Product Definition and Core Structure

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

II,Technical Parameters and Performance Specifications

III,Application Scenarios and Value Proposition

1. Mechanical Equipment Field

• Automation equipment supports: Full threads match nuts for stepless height adjustment (e.g., assembly line support columns with hollow channels for air hoses/signals).
• Vibration mechanical connections: Full-thread engagement resists vibration (e.g., mining/textile machinery), replacing welding for easy disassembly.

2. Electrical Engineering Field

• Cabinet cable routing: Hollow channels route cables; external threads secure to cabinet panels (e.g., PLC cabinets, sensor bases), integrating connection and wiring.
• Lighting systems: Hollow rods suspend fixtures, with internal channels for power cables and external threads for height adjustment (e.g., mall chandeliers, industrial lighting).

IV,Differentiated Competitive Advantages

• 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 a 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.

V,Selection and Installation Guide

1. Three-Step Selection Method

• Thread Priority: Choose between M/G/NPT. Tapered NPT suits high-pressure scenarios; parallel G/M require seals.
• Material Decision: For humid/corrosive environments, choose 304/316 stainless steel; for dry environments, zinc-plated carbon steel (cost reduction ≥30%).
• Length Customization: Standard lengths: 20~100mm. Custom lengths available (≤500mm for extra-long, ≥10mm for extra-short).

2. Installation Tips

• Sealing: For fluids, use PTFE tape (≥5 wraps) or Loctite 577; structural connections can be screwed directly.
• Torque Control: For M16, recommended torque: 30–40N·m. For pipe threads, tighten 1/4 turn after hand-tightening.
• Anti-Loosening: For vibration, use slotted nuts (GB6178) + cotter pins or Loctite 243.

VI,Customization and Quality Assurance

• 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.
