Product Description
Product Overview
This product is an internal thread welded round nut complying with DIN934 standard, manufactured from Q235 carbon steel through cold heading process. The product has a cylindrical shape and can form a firm connection with the base material through peripheral fillet welding or end face welding. It provides high-strength internal thread fixing points for metal structural parts, especially suitable for connection scenarios that require compact space and closed appearance.
Core Advantages
-
Compact Structure and High Strength: The cold heading process ensures the integrity of metal flow, resulting in high product density and strong load-bearing capacity.
-
Flexible and Reliable Welding: The cylindrical shape supports various welding methods such as fillet welding and plug welding, ensuring firm connection.
-
Optimized Installation Space: The cylindrical design saves installation space, suitable for the interior of compact or closed structures.
-
Economical, Practical and Efficient: Q235 material combined with cold heading process has cost advantages while ensuring high performance.
Applicable Industries
-
Heavy Machinery Equipment: Connection of boxes and covers of heavy equipment such as construction machinery, mining equipment and agricultural machinery.
-
Steel Structure Construction and Engineering: Connection nodes requiring high-strength embedded nuts such as bridges, plant steel structures and towers.
-
Automotive and Rail Transit: Key structural connections such as commercial vehicle frames, rail vehicle underframes and engine brackets.
-
Power and Energy Equipment: Fastening and installation of equipment such as wind power towers, transformer boxes and high-voltage switch cabinets.
-

-
Marine and Offshore Engineering: High-load-bearing fastening points such as internal hull structures and offshore platform modules.
-
Military and Special Equipment: Fields with extremely high requirements for connection strength and reliability, such as special vehicles, shelters and weapon hangers.
Warm Tips
-
Before welding, please thoroughly clean the surface of the workpiece and the welding area of the nut to ensure no oil, rust or impurities.
-
It is recommended to select the appropriate welding method (such as MAG/MIG welding, manual arc welding) and welding parameters according to the base material and thickness.
-
For key load-bearing parts, it is recommended to conduct welding process qualification to ensure that the connection strength meets the design requirements.
