Flange Bolt – Heavy Duty

Heavy-duty flanged hex bolts are designed for demanding structural and industrial applications where high clamping force and maximum load distribution are essential. The extra-wide flange provides a significantly larger bearing area than standard flange bolts, making them suitable for pipe flange joints, industrial equipment mounting, base plate connections, and high-torque structural connections. Manufactured from Grade 10.9 alloy steel and heat-treated for superior tensile and proof load properties, these bolts are commonly specified for oil and gas pipelines, pressure vessel assemblies, and heavy industrial machinery. Hot-dip galvanised finish is available for outdoor and corrosive environments requiring long-term protection.
