Carbon Steel GB/T 16674.1-2004 Hexagon flange bolt of Fine rod flange-Type U

Hexagon flange bolts of Fine rod flange-Type U are available in thread sizes M5-M16, with pitches ranging from 0.8mm to 2mm, and surface treatments such as oxidization and plating can be applied as required to meet different requirements for strength and corrosion resistance. The flange face is designed as U-shape (or known as with countersunk groove type), which helps to enhance the sealing performance of bolts and connectors and reduce stress concentration. They are widely used in automobile, machinery, construction, chemical industry and other fields.
 
Product Characteristics

• Thin rod design: U-shaped thin rod structure, suitable for precision assembly and narrow space, reducing material waste and improving assembly efficiency.
• Flange surface increases contact area: flange surface design effectively increases the contact area with the workpiece and improves the connection stability and load capacity.
• High-quality materials: Adopting stainless steel, medium carbon steel and other high-quality materials with good corrosion resistance and strength, adapting to a variety of working environments.
• Precision processing: After precision processing and strict inspection, the thread accuracy, surface finish and dimensional accuracy of the bolts are ensured.

 
Application
