Product Description

The U-bolt M12x57 clamp is a heavy-duty M12x57 U-bolt fastener designed for robust suspension and mounting applications. Featuring a 12mm diameter threaded shaft with 57mm leg length, this 12mm U-bolt suspension component provides secure clamping force for pipes, brackets, or structural supports in industrial settings. Constructed from galvanized steel for corrosion resistance, it operates reliably across temperatures from -40°C to 120°C and handles static loads up to 2.5 kN. The U-bolt M12x57 clamp integrates seamlessly with standard M12 mounting hardware, offering a 30-35mm inner clearance for versatile attachment. Widely used in automotive, construction, and machinery industries, its key advantages include high tensile strength and straightforward installation, though precise alignment is required during assembly to ensure uniform stress distribution. Compliant with DIN/ISO specifications, it ensures compatibility with industrial-grade fastening systems.
