The 12-point flange screw is a durable-performing fastener designed for demanding applications. Also known as a ferry cap screw or a double hex head screw, they offer superior torque capacity & reliability. These fasteners feature a 12-point head & a built-in washer-like flange. These attributes provide an even distribution of clamping force. Two commonly stocked exotic alloys at Nickel Systems are Inconel 718 & A286. These alloys maintain exceptional strength, corrosion resistance, & the ability to maintain integrity under high temperatures & pressures. These 12-point flange screws are used by industries such as aerospace, power generation, & chemical processing. Whether you’re assembling components for a jet engine or a critical refinery system, these screws deliver unmatched durability & precision. At Nickel Systems, we are proud to offer an extensive inventory of 12-point flange screws crafted from exotic alloys to meet your exact specifications. Explore our selection today, and let us help you secure the components you need for your toughest projects.

A 12-point flange screw is a fastener that has 12 contact points on its head. It also has a flange. This is in contrast to standard hex head bolts, which only has 6 points. The additional contact points allow for higher torque application. The integrated washer like base creates a larger bearing surface to evenly distribute the clamping force. This removes the need to purchase additional washers.
