Carbon Steel Threaded Connector Nut , Fully Threaded Pipe For Lighting / Furniture

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.

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 such 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.
