Some Considerations for Selecting Fully Threaded Studs

1、 Structural characteristics
Full-thread design: Full-body thread for length adjustment and flexible installation.
Various specifications: the diameter range is M6-M64, the length can reach over 3m, and it conforms to GB/T 5782, ISO and other standards.
2、 Performance advantages
Anti-corrosion and durability
The zinc layer is isolated from oxygen and water, and effectively resistant to salt and alkali, moisture, marine climate and other corrosive environments.
High strength and toughness
The tensile strength reaches 8.8 and above, and can withstand heavy load impact and high frequency vibration.
Cost-effective and efficient
Galvanizing process cost is low, maintenance-free feature reduces long-term use cost.
3、 Recommendations for model selection
Corrosive environment: hot galvanized studs are preferred;
Dynamic load: matched with high-strength materials (such as alloy steel);
Installation Efficiency: Full-thread design for applications requiring frequent adjustments.
4、 Plating and Surface Preparation
Hot galvanizing: the thickness of zinc layer is 50-100 μ m, applicable to outdoor electrical equipment and bridge steel structure.
Dacromet: salt mist corrosion resistance is superior to galvanization, which is used for automobile chassis and coastal chemical equipment.
PTFE coating: reducing friction coefficient, anti-adhesion, suitable for food processing equipment and pharmaceutical machinery.
5、 Material classification and typical application:
Carbon steel material
Q235 series: low cost, moderate strength, applicable to general building structure and non-load-bearing mechanical connection, and the corrosion resistance shall be improved with the galvanizing process.
No.45 steel (C45E): the strength after heat treatment can reach Grade 8.8, which is used for fixing medium load equipment, such as machine tool and conveyor belt.
Stainless steel material
304：Universal stainless steel, resistant to weak acid and salt mist, applicable to food machinery and indoor pipe connection.
316：Molybdenum contained, resistant to chloride ion corrosion, suitable for sealing reactors in marine engineering and chemical plants.
Alloy steel material
Chromium-molybdenum alloy steel:

35CrMo: tensile strength ≥ 980MPa, high temperature resistance to 550 ℃, used for connection of power station boiler and oil drilling equipment.
42CrMo: higher strength (Grade 12.9) for mine machinery, heavy truck chassis.
