U Bolts

U Bolt Product Describsion

U bolts are Boltead’s main product. We are a manufacturer and supply of these bolts. While producing and supplying these bolts, we also produce nuts, washers and other fastener products used in conjunction with them.

These bolts we produce are generally classified according to whether the material is carbon steel or stainless steel. More specific classifications are as follows:

Carbon steel U bolts are generally classified according to strength levels. The more common strength levels are: 4.8, 8.8, 10.9, and 12.9. Among them, bolts with grade 8.8 or above are generally called high-strength bolts （high tensile bolts）.Stainless steel U bolts are generally classified according to different materials. The more common stainless steel materials are SUS201 SUS304 SUS316

In addition to different materials and strengths, the biggest impact on U bolts is surface treatment. The following are the more common surface treatments for these bolts: black oxide, black zinc, zinc plated (ZP), color zinc plating (CZP /YZP), hot dip galvanized (HDG), dacromet coating, etc.

U Bolt Production Process

U bolts are sent from the raw material line to the final product. They generally go through the following process:
Annealing of raw materials – pickling – drawing – forming – grinding – heat treatment – surface treatment – classification – packaging – shipping

The rough schematic diagram is as follows:

U Bolt Application fields

Examples of Uses of U Bolts:

1. Pipe and Tube Support: These bolts are commonly used to secure pipes, tubes, conduits, and cables to structural supports such as beams, poles, and walls. They provide a secure and stable mounting solution for plumbing, HVAC (Heating, Ventilation, and Air Conditioning), electrical, and mechanical systems in residential, commercial, and industrial buildings.
2. Vehicle Suspension: These bolts are integral components of vehicle suspension systems, where they are used to secure leaf springs, axle assemblies, and other suspension components to the chassis or frame of vehicles such as trucks, trailers, and buses. They provide the necessary clamping force to maintain the alignment and stability of the suspension system under dynamic loads and road conditions.
3. Marine and Boat Hardware: In marine applications, These bolts are utilized for securing rigging hardware, lifelines, and other equipment on boats, yachts, and marine structures. They are corrosion-resistant and provide a reliable attachment point for securing sails, ropes, fenders, and other accessories in saltwater environments.
4. Outdoor Structures: These bolts find applications in the construction and assembly of outdoor structures such as fences, guardrails, handrails, and utility poles. They are used to fasten structural components together and provide reinforcement and stability to outdoor structures exposed to wind, weather, and environmental forces.
5. Vehicle Exhaust Systems: These bolts are commonly used in vehicle exhaust systems to secure exhaust pipes, mufflers, and catalytic converters to the underside of vehicles. They provide a secure and durable mounting solution for exhaust system components, ensuring proper alignment, support, and vibration resistance to prevent leaks and noise.
6. Pipe Hangers and Supports: These bolts are employed in pipe hanger and support systems to suspend and support pipes, ducts, and conduits from overhead structures such as ceilings, beams, and trusses. They are used in conjunction with pipe clamps, clevis hangers, and threaded rods to create customized pipe support configurations in plumbing, HVAC, and industrial piping systems.
7. Agricultural Machinery: These bolts are used in agricultural machinery and equipment for securing components such as axles, blades, brackets, and hitch assemblies. They provide a robust fastening solution for agricultural implements, trailers, and equipment used in farming, landscaping, and construction applications.

These examples demonstrate the versatility of U bolts across a wide range of industries and applications, showcasing their importance in providing secure and reliable fastening solutions for various structural, mechanical, and automotive systems.
