Product Description
U-shape bolts are primarily used in cargo vehicles to stabilize chassis and frame components, such as connecting steel plate springs. These versatile fasteners find applications in construction, mechanical connections, vehicles, ships, bridges, tunnels, and railways.
U-bolt , Characteristics are summarised in one sentence:
Embracing clamping: half-circle embracing pipe/rod, double nut locking, even force without flattening.
Anti-vibration anti-loosening: three-point contact, residual preload, vibration conditions can not be loose.
Fast mounting and dismantling: the nut can be taken out radially as soon as it is loosened, no need to put the tube in from the beginning.
Material with the scene: carbon steel 8.8 grade, stainless steel 316, hot-dip galvanised, HDG, Dacromet, can be outdoor and acid-resistant.
Flexible specifications: diameter M6-M42, arc R can be customised, the leg length of any cut-off, a piece can also be done.
Low cost: cold-formed + turning teeth, no dolly fee, than the same specification flange + clamp to save half the money.
Available Shapes
- Semi-circular
- Square right angle
- Triangle
- Oblique triangle
Material Properties
