Our Round Head U Bolts are robust fastening solutions designed for secure and reliable connections in diverse industrial and structural applications. Crafted from high-strength carbon steel with an 8.8 performance grade, these bolts offer excellent tensile strength to withstand heavy loads and dynamic stress, ensuring long-term durability in demanding environments. The round head design provides a balanced load distribution, while the common bolt connection method allows for easy installation across various setups.

Key Features

• Material: Premium carbon steel construction for superior hardness and structural integrity, ideal for heavy-duty use.

• Head Shape & Type: Round head profile and classic U bolt design, delivering a wide bearing surface and resistance to rotational forces during assembly.

• Performance Grade: 8.8 rating ensures tensile strength up to 800MPa, making them suitable for high-stress applications like machinery mounting and structural supports.

• Surface Treatment: Available in polishing, plain, zinc-plated, or phosphated finishes to meet specific corrosion resistance needs-zinc plating offers enhanced protection in humid or corrosive environments, while polished surfaces provide a clean, professional appearance.

• Standards & Sizes: Compliant with international and national standards including DIN, ANSI, GB, JIS, BSW, and GOST, ensuring global usability. Sizes range from M10 to M24 as standard, with custom dimensions available to fit unique project requirements.

Applications

These U bolts are widely used in:

• Mechanical Engineering: Securing gears, motors, and hydraulic components in heavy machinery to maintain stability under vibration and load.

• Chemical Industry: Anchoring pipelines and equipment in refineries or processing plants-zinc-plated or phosphated finishes resist corrosive chemicals and harsh atmospheres.

• Construction & Infrastructure: Fastening steel beams, concrete formwork, and structural frames in building projects, adhering to strict safety standards for reliable load-bearing performance.

• Environmental Equipment: Supporting installations in wastewater treatment facilities or air purification systems, where surface treatments like phosphating offer protection against mild acid/alkali environments.

Engineered for versatility and durability, our Round Head U Bolts provide a practical fastening solution for projects that demand strength, compliance with global standards, and adaptability to different environmental conditions. Whether for standard applications or custom designs, they ensure secure connections and long-lasting performance across industries.
