Full Threaded Tube For Lighting And Furniture Connection Support
And Fastening
A full threaded tube is a tubular fastener with a surface covered
in continuous threads. Through its full-thread through design, it
achieves length-adjustable rigid connection or support, and is
widely used in industrial and civil scenarios requiring flexible
docking and load-bearing fastening. Its structure combines the
hollow characteristics of a pipe fitting with the connection
function of threads, making it a core component in connection,
support, and adjustment scenarios.
I. Core Structure and Design Features
- Full-thread through design: The inner and outer surfaces (or outer surface) of the tube are
covered with continuous threads, with thread precision reaching
6g/6H. The thread profile is complete without broken teeth, and the
pitch is uniform (metric coarse/fine threads optional), ensuring
smooth engagement with nuts, joints, and other accessories, with an
effective engagement length ≥90%.
- Hollow tubular structure: The tube is hollow (inner diameter designed according to
specifications, e.g., inner diameter of M10 full threaded tube
≥6mm), balancing lightweight and structural strength. It can be
used for threading, pipe passing, or as a fluid channel (with
seals).
- Mechanically optimized design: The tube wall thickness is uniform (tolerance ±0.1mm), and the
thread root is rounded (R≥0.3mm) to reduce stress concentration.
Its shear resistance is better than that of smooth tubes of the
same specification, adapting to both dynamic and static loads.
II. Core Parameter Specifications
| Parameter Category | Specific Parameters | Detailed Description |
|---|
| Thread Standards | Metric (common specifications M6-M30), American (1/4"-1"),
supporting customization of coarse threads (e.g., M10*1.5) and fine
threads (e.g., M10*1.25). | Complies with GB/T 192 and ISO metric thread standards, with a
thread angle of 60°, ensuring universality. |
| Material and Surface Treatment | Base Materials | Carbon Steel (Q235/45#): Tensile strength ≥375MPa, suitable for
medium-load scenarios; Stainless Steel (304/316): Salt spray resistance ≥72 hours,
corrosion-resistant, used in humid/chemical environments; Zinc Alloy: Easy to process, suitable for light-load decorative
scenarios. |
| Surface Treatment | Zinc Plating (color zinc/white zinc): Zinc layer 8-12μm, salt spray
resistance ≥48 hours, cost-effective for anti-corrosion; Chrome Plating: Hardness ≥800HV, wear-resistant and aesthetic, used
in precision equipment; Stainless Steel Passivation: Enhances rust resistance, maintaining
the metal's natural color. |
| Specification Parameters | Diameter * Length | Diameter: M6-M30 (larger specifications customizable); Length:
50mm-3000mm (supporting cutting/butt joint extension). |
| Tolerance Control | Outer diameter tolerance ±0.2mm, wall thickness tolerance ±0.1mm,
thread tolerance 6g, ensuring accessory compatibility. |
III. Core Performance Advantages
- Strong connection flexibility: The full-thread design can be paired with nuts and joints to
achieve arbitrary length adjustment, enabling quick docking without
additional processing, adapting to connection needs with different
spacings (e.g., height adjustment of furniture, fine adjustment of
equipment support height).
- Reliable load-bearing and support: The M10 full threaded tube made of carbon steel has a static load
capacity ≥500kg (when fixed with double nuts) and a bending
strength ≥200MPa, suitable for load-bearing components suchs as
support columns and suspension rods.
- Multi-functional adaptability: The hollow structure can integrate functions such as threading
and water passage, e.g., threading wires in lighting brackets and
passing water in irrigation equipment, achieving "connection +
function" integration.
- Easy installation: No professional tools are required; it can be fixed by tightening
nuts with a wrench, and is reusable for disassembly and adjustment,
with low maintenance costs.
IV. Typical Application Scenarios
- Furniture and Home: Adjustment of table and chair support legs, fixing of wardrobe
hanging rods, height adjustment of bookshelf laminates. Zinc-plated
carbon steel models balance strength and corrosion resistance,
adapting to indoor environments.
- Construction and Decoration: Connection of ceiling keels, fixing of display rack columns,
support of guardrail handrails. Stainless steel models are suitable
for humid areas (e.g., bathrooms, outdoor terraces).
- Machinery and Equipment: Support of small mechanical guide rails, adjustment of assembly
line brackets, fixing of instrument and equipment feet. Fine-thread
models enable precise length adjustment.
- Lighting and Water/Electricity: Connection of chandelier suspension rods, fastening of street
lamp brackets, transition connection of water/gas pipes. The hollow
structure facilitates threading or fluid passage.
V. Installation and Maintenance Recommendations
- Installation Points: When paired with nuts, ensure complete thread engagement
(engagement length ≥1.5 times the thread diameter). For
load-bearing scenarios, it is recommended to use double nuts for
anti-loosening (upper and lower nuts locked); after cutting, clean
thread burrs to avoid accessory jamming.
- Maintenance Notes: For carbon steel models, regularly check the integrity of the
zinc coating; if rust is found, clean it promptly and touch up with
anti-rust paint. For stainless steel models, avoid contact with
carbon steel to prevent electrochemical corrosion. For load-bearing
components, check the tightness of nuts every 6 months to avoid
loosening.
With the core advantages of "full-thread flexible connection +
multi-functional tubular structure", full threaded tubes provide
efficient connection and support solutions in industrial, home, and
construction fields, balancing adjustment flexibility, structural
strength, and scenario adaptability, making them an ideal choice
for lightweight fastening scenarios.
