Product Details
Stainless Steel Flange Bolts are premium fasteners designed for applications requiring high resistance to corrosion, as well as structural strength. These bolts feature a flange head that provides a large bearing surface, making them ideal for use with thin or soft materials where a larger contact area is needed to distribute the clamping force.

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.
Used extensively in marine environments, food processing industries, and medical equipment where hygiene and corrosion resistance are paramount.
Ideal for structural applications in corrosive or wet environments, such as chemical plants or water treatment facilities.
Suitable for automotive and aerospace applications where a combination of strength and corrosion resistance is required.
