About Flange Bolts

Flange Bolts are designed of connecting two parts or section together. These have great usage in the industry of furniture, engineering, and automotive to name a few. Having strength, and perfect threading, thickness & length, these ensure strong fastening of the parts. They are connected easily by using forged steel nuts. The offered Flange Bolts are casted with sophisticated machine using Grade-A steel metal, and finished with chosen coating/polishing material to guarantee their ability to withstand high pressure, and resistance to rust formation.

Precision Engineering for Enhanced Performance

Each flange bolt is meticulously crafted to ensure a tolerance of 0.2 mm and is available in hardness levels between 22-45 HRC. The hexagonal head with an integrated flange delivers a wide bearing surface, effectively dispersing load and reducing vibration. This design eliminates the need for additional washers, streamlining installation and providing reliable, anti-loosening performance.

Versatile Applications and Custom Packaging

Our flange bolts cater to a wide array of industries, offering flexibility in thread types, grades, finishes, and packaging (box, bulk, or customized). From automotive assembly lines to heavy machinery and construction projects, our bolts can be tailored to meet your exact specifications, ensuring superior strength and corrosion resistance across varying environments.

FAQs of Flange Bolts:

Q: How are flange bolts installed for maximum load-bearing capacity?

A: Flange bolts should be torqued to the recommended value specified for their sizeup to 400 Nm for larger diameters. Always ensure surfaces are clean and bolts are appropriately matched to the application to maximize bearing capacity, which can reach up to 2 tons depending on the size.

Q: What benefits do flange bolts offer compared to standard bolts with washers?

A: Flange bolts with an integrated flange provide a wider bearing surface, reducing vibration and minimizing the likelihood of loosening. This design removes the need for separate washers, streamlining installation while maintaining a secure attachment, especially in high-vibration or high-load scenarios.

Q: Where can these flange bolts be used effectively?

A: These bolts are ideal for use in automotive, construction, and industrial machinery applications. Their rust-proof and high-strength characteristics make them suitable for both indoor and outdoor environments with temperatures ranging from -20C to +300C.

Q: What materials and finishes are available for your flange bolts?

A: Our flange bolts are available in carbon steel, alloy steel, and stainless steel, with surface treatments such as zinc plating, black oxide, and hot dip galvanization. You can choose from bright, matt, or coated finishes depending on your specific requirements.

Q: When should I choose a full thread versus a partial thread bolt?

A: Full thread bolts are ideal for maximum grip along the entire length, beneficial for assemblies needing a tight, secure fit. Partial thread bolts are preferable when a shear plane or higher clamping force is desired, typically in load-bearing or structural applications.

Q: How does RoHS compliance benefit my projects?

A: RoHS compliance ensures that the flange bolts are free from hazardous substances, making them suitable for use in environmentally regulated projects and contributing to safer, eco-friendly construction and manufacturing practices.

Q: What packaging options are available for your fasteners?

A: We offer flexible packaging solutions including box, bulk, or customized packaging to accommodate different project sizes, shipping requirements, and handling needs. This ensures bolts arrive in optimal condition and in quantities best suited to your operations.
