Stay Wire Assembly Fititngs manufacturer standard. U-shaped bolts, namely riding bolts, with the English name U-bolt, are non-standard parts. The shape of Stay Wire Assembly Fititngs is U-shaped, so it is also called U-shaped screw, U-shaped pipe clamp, U-shaped card, U-shaped wire or clip. There are threads on both ends that can be combined with a nut. It is mainly used to fix tubular objects such as water pipes or sheet objects such as leaf springs of cars. Because Stay Wire Assembly Fititngs fix objects in the same way as a person riding on a horse, they are called riding bolts.
Fasteners are based on Stay Wire Assembly Fititngs' national implementation standard JB/ZQ4321-2006 "U-shaped bolts" and material selection standards are based on GB700-2006 "General Carbon Structural Steel Technical Conditions". Steel with strength not less than 72.5N/mm2 (372.5MPa).
According to the material structure, it is divided into two categories. The first is ordinary carbon structural steel, which is what we usually call carbon steel; the second is stainless steel. The steel of Stay Wire Assembly Fititngs that we often use is carbon steel. Carbon steel is divided into Q235, Q345 and alloy steel according to the carbon content and strength of the steel. There is also stainless steel, which is divided into 304, 321, 304L, 316, 316L, 317, 317L, 310S and so on.
According to the strength, it is also divided into two categories, one is the low-strength Stay Wire Assembly Fititngs, and the other is the high-strength Stay Wire Assembly Fititngs. The strength grades are divided into more than ten grades such as 3.6, 4.8, 5.6, 6.8, 8.8, 10.9, and 12.9. Stay Wire Assembly Fititngs with material strength of 6.8 and below are low-strength type, and those with material strength above 6.8 are high-strength type.
