High-Strength Hex Flange Bolts
Hex flange screws are a type of bolt that has a hexagonal head and an integrated flange. The flange helps distribute the load of the screw, providing a stronger grip and reducing the chance of damage to the material being fastened. They’re often seen in automotive, construction, and machinery applications.
Valley Fastener manufactures hex flange bolts in a variety of sizes. We have the ability to manufacture 1/4″ thru 5/8″ diameter up to 6″ in length. We manufacture both inch and metric hex flange bolts in various grades for your specific application requirements.
