U-bolt, that is, riding bolt, the English name is U-bolt, it is a non-standard part, the shape is U-shaped, so it is also called U-bolt. The two ends are threaded and can be combined with the nut. It is mainly used to fix tubular objects such as water pipes. Or a sheet, such as a leaf spring of an automobile, is called a riding bolt because it fixes the object like a person riding on the horse. Below is a small series to see what the U-bolt specification is. How to choose the bolt grade.
U-bolt specification method
First you need to label the thread size, and then the outer diameter of the tube that requires the card.
Standard marking example for u-bolts
The mark of the U-bolt for the fixed outer diameter D0=25mm pipe;
Fixed outer diameter D0=25mm for the pipe, marking the surface of the galvanized U-bolt;
U-bolt feature description
The U-shape is generally used on trucks, which are used to stabilize car sites and frames. For example, leaf springs are u-bolts to connect.
U-bolts are widely used, mainly for construction and installation, mechanical parts connection, vehicle ships, bridge tunnels, etc. Main shapes: semi-circular, square right angle, triangle, oblique triangle, etc.
1, Material property density, bending strength, impact toughness, compressive strength, modulus of elasticity, tensile strength, temperature resistance, and color are determined according to the use environment.
2, the material commonly used are carbon steel Q235AQ345B alloy steel stainless steel and so on. Among them, stainless steel materials are 201304, 321, 304L, 316, 316L.
3, the national standard for u-bolts.
