Product Overview
U-shape bolts are primarily used in cargo vehicles to stabilize chassis and frame components, such as connecting steel plate springs. These bolts find extensive applications in construction, mechanical parts connection, vehicles, ships, bridges, tunnels, and railways.
Available Shapes
- Semi-circular
- Square right angle
- Triangle
- Oblique triangle
Material Specifications
Our U-bolts are manufactured with various material properties including density, bending strength, impact toughness, compression strength, modulus of elasticity, tensile strength, and temperature resistance. Colors can be customized based on usage environment.
Common materials include carbon steel (Q235A, Q345B), alloy steel, and stainless steel (201, 304, 321, 304L, 316, 316L). The national standard for U-bolts is JB/ZQ4321-2006.

Thermal Tightening Applications
Thermal tightening is required for pipeline bolts where internal medium temperature exceeds 200℃. This process ensures proper sealing as temperature changes cause bolt expansion.
Hardness Measurement
Steel hardness is measured using Brinell (HB) or Rockwell methods. Brinell hardness measures indentation area from a steel ball impact, while Rockwell measures penetration depth.
Material Enhancement
Steel properties can be enhanced through alloy mixing:
- Carbon increases hardness and rigidity but reduces toughness
- Chromium improves hardness with less impact on toughness
- Titanium enhances both hardness and toughness
Heat treatment processes like quenching (rapid cooling) increases hardness while tempering (slow cooling) improves strength and toughness.
