High Strength Hexagonal Male Thread Adapter Nut With Good Toughness

Product Specification

Hexagonal Male Thread Adapter Nut: lighting & furniture connection/fastening.

I. Product Basic Information
This 1/8-27 thread × 15MM hexagonal male adapter is made of carbon steel. Carbon steel features high strength and good toughness, meeting the needs of various industrial environments. Its thread specification is 1/8-27 threads, compliant with the American NPT (National Pipe Taper) tapered pipe thread standard, with a taper ratio of 1:16, a thread angle of 60°, and an overall length of 15MM.

II. Core Parameters

III. Design Features

• Thread Design
  Adopts American NPT tapered pipe threads, which have excellent sealing performance. During connection, as the threads are tightened, they form a tight fit, effectively preventing medium leakage.
  High-precision thread processing ensures good compatibility with matching pipe fittings, reducing installation difficulties and poor sealing caused by thread mismatch.
• Hexagonal Head Design
  The size of the hexagonal head is carefully designed to match common wrench specifications, facilitating installation and disassembly and improving work efficiency.
  The thickness and strength of the head are optimized to withstand large torque without deformation or damage during tightening.

IV. Surface Treatment
To enhance the corrosion resistance and aesthetics of the adapter, carbon steel adapters are usually subjected to surface treatments, with common methods as follows:

• Galvanizing Treatment
  Hot-dip galvanizing is a commonly used surface treatment method, with a zinc coating thickness typically between 20-50μm. The hot-dip galvanized layer forms a dense protective film on the adapter surface, effectively preventing carbon steel from rusting and corroding, and extending the service life.
  Galvanized adapters have a silvery-white luster, with an attractive appearance and certain decorative properties.
• Black Oxide Treatment
  Black oxide treatment forms a black oxide film on the adapter surface through chemical methods. This oxide film not only improves corrosion resistance but also enhances surface wear resistance.
  Adapters after black oxide treatment have a uniform surface color, giving a calm and professional look, suitable for occasions with certain appearance requirements.

V. Application Scenarios

• Industrial Pipeline Systems
  Used in pipeline systems of chemical, petroleum, power, and other industries to connect various pipe fittings, valves, instruments, and other equipment, realizing medium transportation and control. For example, in chemical production, it can connect pipelines transporting corrosive media such as acids, alkalis, and salts; in oil exploration and refining, it can connect oil pipelines and refining equipment.
• Mechanical Equipment
  Serves as a connecting component in various mechanical equipment for power transmission and fluid transportation. For instance, in hydraulic systems, it connects hydraulic pumps, hydraulic cylinders, oil pipes, and other components to ensure the normal operation of hydraulic systems; in pneumatic systems, it connects pneumatic components to realize pneumatic control functions.
• Construction and Decoration Industry
  In building water supply and drainage systems, it connects water pipes, faucets, shower heads, and other equipment to realize water supply and drainage. In decoration projects, it connects some metal decorative components to play a fixing and connecting role.

VI. Installation and Maintenance

• Installation Points
  Before installation, ensure the thread surfaces of the adapter and matching pipe fittings are clean, free of oil, debris, and rust. Clean with a clean cloth or brush.
  During installation, use a suitable wrench to tighten according to the specified torque. Generally, for 1/8-27 thread adapters, the recommended tightening torque is 5-10N・m. Over-tightening may damage threads and affect sealing performance; under-tightening may cause leakage.
  During installation, sealing materials such as PTFE tape or sealant can be used as needed to improve sealing performance. When wrapping PTFE tape, wrap it in the correct direction (usually clockwise) with no more than 2-3 layers.
• Maintenance Recommendations
  Regularly inspect the connection part of the adapter for leakage, looseness, etc. If leakage is found, stop use immediately and repair or replace the adapter.
  During use, avoid external impact or excessive twisting on the adapter to prevent damage to its structure and sealing performance.
  If the adapter is in a humid or corrosive environment for a long time, regularly maintain it, such as applying anti-rust oil and checking the integrity of the galvanized or black oxide layer, to extend its service life.

VII. Comparative Advantages
Compared with adapters of the same specification made of other materials, the 1/8-27 thread × 15MM hexagonal male adapter (carbon steel) has the following advantages:

• Cost Advantage
  Carbon steel is a common and economical metal material with relatively low raw material costs. Therefore, carbon steel adapters have a price advantage, suitable for large-scale use and cost-sensitive projects.
• Strength Advantage
  Carbon steel has high strength and good toughness, able to withstand large pressure and tension. In industrial applications with high strength requirements, carbon steel adapters can better meet usage needs and ensure system safety.
• Machinability Advantage
  Carbon steel has good machinability, easy to undergo forging, cutting, welding, and other processing processes. This enables carbon steel adapters to be custom-processed according to different design requirements and usage scenarios, meeting diverse needs.
