Product Details
Flange bolts are composed of hexagonal heads and flanges. The "ratio of supporting area to stress area" is larger than that of ordinary bolts. Therefore, this type of bolt can withstand higher pre-tightening force and has better anti-loosening performance, so it is widely used. Used in automobile engines, heavy machinery and other products.

Material: Made from high-quality stainless steel, such as grades 304, 316, or 410, which offer varying levels of corrosion resistance.
Flange Head: A flange head design that prevents the bolt from sinking into materials and provides a larger surface area for torque distribution.
Corrosion Resistance: Excellent resistance to rust and corrosion, making these bolts suitable for outdoor applications and environments with exposure to moisture or chemicals.
High Strength: Despite their corrosion resistance, stainless steel flange bolts maintain high tensile strength, suitable for heavy-duty applications.
Precision Threads: Precisely machined threads ensure compatibility with corresponding stainless steel nuts and other fastening systems
