M5 M6 Stainless steel Hexagon Flange Nuts SS304 SS316 A2 A4-81 Hex Thin Nuts

Hexagonal nuts are designed to work in conjunction with screws and bolts to provide secure fastening for machine parts. These nuts are categorized into three types based on thickness: Type I, Type II, and thin nuts. Type I hexagonal nuts are the most commonly used, with A and B grade nuts suitable for precision applications requiring smooth surfaces, while C grade nuts are ideal for rougher surfaces.

The design of hexagonal nuts provides excellent torque transmission capacity and can withstand significant axial and radial loads. Type II hexagonal nuts feature greater thickness for applications requiring frequent assembly and disassembly, while thin hexagonal nuts are designed for space-constrained applications.

• Construction: Used in steel structures, frames, and bridges to ensure component stability and safety
• Mechanical Engineering: Essential for fixing parts in automotive, marine, aviation, and machine tool equipment
• Electronics: Special hexagonal bolts ensure tightness and stability of electronic components
• Home Maintenance: Commonly used in furniture assembly and bicycle repairs

Available in various stainless steel grades including SUS304, 304L, 316L, 316, 316Ti, 410, 420, and specialty alloys like Inconel718, GH4169, and C276. 304 stainless steel (18/8 stainless steel) offers excellent processing performance and high toughness, with temperature resistance up to 800℃.

For optimal performance, match bolt grades with corresponding nut grades. An 8.8 grade bolt should be paired with an 8 grade nut, while a 10.9 grade bolt requires a 10 grade nut. This ensures proper strength matching and safety in applications.

Available in small packing, carton packing, or pallet options. All products undergo rigorous quality inspection before shipment to ensure compliance with specifications.
