U-bolt product standard: national standard :JB/ zq4321-1997, German standard :DIN3570, can also be produced according to customer's drawings and samples.Product specification: diameter :M6-- -m64,1/4 "--2-1/2", length is not limited.Product grade: can run 4.6, 5.6, 6.8, 8.8, 10.9, 12.9.Or SAE J429, ASTM A307, ASTM A325, ASTM A490.Product surface: blackening, yellow zinc plating, white zinc plating, hot dip galvanizing, hot dip galvanizing, dacromet plating.

U bolt, namely riding bolt, riding bolt English name is u-bolt, non-standard parts, is the shape of the U shape so also known as U screw,U tube card,U tube clip, both ends of the thread can be combined with the nut, mainly used to fix the tube like water pipe or flake such as automobile plate spring.The standard for fasteners such as u-bolts is the norm, and each country and department has its own standard.At present, the most commonly used standards in our daily business are as follows:

GB -- Chinese national standard (GB)ANSI -- American national standard (GB)

DIN - German national standard (German standard)ASME - American society of mechanical engineers standard

JIS -- Japanese national standard BSW -- British national standard

GB - the national standard is one of the many standards in our country, there are also industry standards, professional standards and departmental standards.National standard divides again :GB(strong system sex standard) and GB/T(recommend sex standard) and GBn(country interior standard) wait.What we usually see like GB30,GB5783 and so on are mandatory standards.

Above a few kinds of standard besides a few basic dimensions are like head opposite edge, head thickness is waited for different besides, the most main is whorl part is different.GB, DIN, JIS and other threads are MM(MM) for the unit, collectively known as the metric thread.Another thread such as ANSI, ASME etc is in inches called American standard thread.In addition to metric and American threads there is a BSW - British standard, also in inches, known as wyeth threads.

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 ,.
