DIN3570 U-bolts are U-shaped fasteners with threads on both ends that can be used in combination with nuts. They are commonly used to secure tubes such as water pipes or sheets such as leaf springs in automobiles.

Material: including carbon steel, alloy steel, stainless steel (such as 304, 316, 316L, etc.) and other materials, the specific selection depends on the working environment and application requirements.

Grade: The product grade is divided into A grade and B grade, as well as different mechanical properties grade (such as 4.8 grade, 8.8 grade, 10.9 grade,A2-70, etc.), these grades reflect the tensile strength, yield strength and other mechanical properties of the bolt. Different grades are suitable for different load bearing requirements and working environments.

The advantage is:

1. High strength: U-bolts are usually made of high-strength materials, such as stainless steel 304/316, carbon steel and alloy steel, which can provide strong clamping force and durability.

2. Corrosion resistance: U-bolts made of stainless steel, in particular, perform well in wet or chemical environments and are not easy to rust.

3. Easy to install: U-bolts are simple in design, easy to install and remove, suitable for quick construction and maintenance.

4. Adjustability: U-bolts can be adapted to different installation needs by adjusting the position of the nut.

5. Reuse: Compared with disposable fasteners, U-bolts can be used many times, which is economical and efficient.

Scope of 

application

1. Building installation: used for connecting beams, columns, wall panels and other components to improve the stability and bearing capacity of the building structure.

2. Mechanical fittings connection: in mechanical equipment to connect a variety of parts or components, such as bearing housing, bearing bracket, rack, etc..

3. Vehicle ship: in the manufacture of automobiles, trains, aircraft and other means of transport, used to connect the frame, wheels, fuselage and other components.

4. bridge tunnel railway: in large infrastructure projects, U-bolts are used to fix and stabilise structures.
