Therefore, when selecting U-bolts, it is necessary to understand their specifications, dimensions, and technical requirements in order to choose the most suitable U-bolt. Next, this article will introduce the specifications, dimensions, and technical requirements of U-bolts for your reference.

1, Specifications and dimensions of U-bolts
U-bolts are classified into various specifications and sizes based on their purpose and the diameter of the fixed pipe. The standard marking example for U-bolts with a pipe diameter of 25mm is as follows:
-The marking for a conventional U-bolt with a fixed outer diameter D0 of 25mm is: U-bolt 25JB/ZQ4321-97;
-The marking of the U-bolt with a fixed outer diameter D0 of 25mm and a galvanized surface is: U-bolt 25-ZnJB/ZQ4321-97.
2, Technical requirements for U-bolts
1. Meet relevant standards
The general technical conditions of U-bolts should comply with the provisions of the national standard GB2314-85 "General Technical Conditions for Electric Power Hardware".
2. Materials and fasteners
(1) U-bolts should be manufactured with steel with a tensile strength not less than 372.5N/mm2 (372.5MPa) in accordance with the requirements of the national standard GB700-79 "Technical Conditions for Ordinary Carbon Structural Steel".
(2) Nuts should be made in accordance with the requirements of the national standard GB41-76 "Hexagonal Nuts (Rough)".
(3) Closed end sales should be made in accordance with the industry standard SD26-82 "Closed End Sales".
