DIN3570 Standard High Strength HDG Carbon Steel U Shape Bolt and nut

DIN3570 Standard High Strength HDG Carbon Steel U Shape Bolt and nut

1.Product Description

What is standard of u bolt, we first to understand what is u bolt, u bolt, u-bolt, English name for u - bolt, are standard parts, named because for u shape, both ends have a thread can be combined with nuts, mainly used in the fixed tube such as pipes or flake content such as automobile plate spring, because of the way its fixed objects, like a person is riding a horse is called u-bolt.

Threads of ANSI, ASME, etc. Are called American standard threads in inches.In addition to metric and American threads there is a BSW - British standard, also in inches, known as wyeth threads.

The metric thread is measured in MM(MM) and has a 60 degree Angle.Both American and British threads are measured in inches.The U.S. thread also has a 60 degree Angle, while the British thread has a 55 degree Angle.As a result of the difference of measurement unit, the expression method that caused each kind of screw thread is not identical also.For example, m16-2x60 represents metric threads.He means that the screw has a nominal diameter of 16MM, a tooth spacing of 2MM, and a length of 60MM. For example, 1/4 -- 20x3/4 represents the thread in British system. He means that the screw has a nominal diameter of 1/4 inch (one inch = 25.4mm), 20 teeth on one inch, and a length of 3/4 inch.In addition, to express American screw, UNC and UNF are usually added after the British screw to distinguish the thick tooth from the fine tooth.

As U-bolts are now being used by a much wider audience to clamp any kind of tubing / round bar, then a more convenient measurement system needs to be used.

Four elements uniquely define any U-bolt:

1. Material type (for example: bright zinc-plated mild steel or stainless steel )
2. Thread dimensions (for example: M10 * 60 mm)
3. Inside diameter (for example: 40 mm - the distance between the legs)
4. Inside height (for example: 100 mm)

2. Specification

3.Application

U-bolts are generally used in the truck, which is used to stabilize the site and car chassis. For example, the leaf spring is connected to the u-bolt.
U-bolts versatile main purposes: construction and installation, machinery parts connected vehicles, ships, bridges, tunnels and railways. Principal shapes: semi-circular, square, rectangular, triangular, oblique triangle.

4.Advantages

1, The material properties of density, flexural strength, impact toughness, compressive strength, elastic modulus, tensile strength, heat resistance, color is determined according to the use environment.

2, The material commonly used carbon steel Q235A Q345B alloy steel and stainless steel. Wherein the stainless steel has 201 304,321,304L, 316,316L ,.
