External threaded hollow lead screws suit Al-steel connections in construction electronics
I,Product Definition and Core Structure
This product is a Hollow Full-Threaded Rod (also known as: Full-Threaded Hollow Lead Screw, Hollow External Threaded Rod), featuring a “full external thread wrapping + hollow through-channel” design:
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
Key Parameters
Technical Analysis
Material System
Stainless steel 304/316 (main choices), carbon steel (galvanized) - 304/316: Resistant to acids, alkalis, and salt spray (salt spray test ≥ 100 hours), suitable for food, chemical, and marine applications. - Galvanized carbon steel: Cost - effective, very suitable for dry environments (salt spray test ≥ 48 hours).
Thread Specification
Pipe threads (G1/8"–G2", NPT1/4"–NPT1"), metric threads (M8–M36) - Pipe threads: G is a parallel pipe thread (requiring a sealant); NPT is a tapered pipe thread (self - sealing, suitable for high pressure). - Metric threads: Designed specifically for mechanical structure connections, with a thread tolerance class of 6g.
Customizable Dimensions
Length: L = 10–100mm (standard: 15/20/25mm); Outer diameter: D matches the thread (e.g., G1/2" outer diameter ≈ 20.95mm); Inner diameter: d = D - 2×wall thickness (wall thickness: 2–5mm) The hollow inner diameter can be customized (e.g., a larger diameter for cable threading), and the wall thickness ensures tensile strength (≥ 200MPa).
Surface Treatment
Stainless steel mirror polishing (Ra ≤ 1.6μm), carbon steel with blue - white galvanizing/colored zinc plating Enhances corrosion resistance and aesthetics. Stainless steel can be customized through passivation, nickel plating, or other special treatments.
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).
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.
