Industrial Applications
-
Heavy Industry: Suitable for extending long bolts in heavy machinery and structural components. The galvanized coating provides excellent corrosion resistance in harsh operating conditions.
-
Mining: Used for bolt connections in underground supports and conveyor equipment. Designed to withstand damp, dusty environments while maintaining rust resistance and high strength.
-
Water Treatment: Connects long threaded rods in valve systems and pipe supports. The galvanized surface effectively resists corrosion from moisture and chemical exposure.
-
Healthcare: Used for extending bolts in non-critical structures of large medical equipment bases and carts. Meets requirements for structural stability and hygiene.
-
Retail Industry: Suitable for assembly and height adjustment of heavy-duty shelving and display cabinets. Provides secure threaded connections and corrosion prevention in warehouse environments.
Frequently Asked Questions
Is the product strictly compliant with the DIN6334 standard?
Yes, the product strictly adheres to the DIN6334 standard, ensuring dimensional accuracy and mechanical performance suitable for high-strength connections.
What specific galvanizing process is used, and how effective is its rust resistance?
Typically employs electro-galvanizing or hot-dip galvanizing processes, providing effective rust protection in general and mildly damp environments.
What is the standard specification range of the product? Does the thread type include both coarse and fine threads?
Standard offerings typically cover thread sizes from M4 to M20, with standard coarse threads (e.g., M8*1.25) as standard. Fine thread specifications usually require customization.
What are the advantages of this coupling nut compared to methods like welding or using a standard nut with a sleeve?
The one-piece extended thread structure enables stable long-distance connections, avoids welding distortion, and offers greater installation convenience and reliability compared to standard nut assemblies.
What is the Minimum Order Quantity (MOQ) and standard delivery time? Is non-standard customization supported?
Standard MOQ is typically 500-1000 pieces or measured by weight/kilos. In-stock specifications have a delivery time of approximately 7-14 days. Customization for special lengths, materials, and surface treatments is supported.
