12-Point Flange Screws

A 12-point flange screw, also known as a 12-point flange bolt, is a specialized fastener designed for high-torque applications. It has distinct characteristics that set it apart from standard bolts and screws: Head Design: The most notable feature is the 12-point head, which has twelve equally spaced points (or splines) around its circumference. This design allows for multiple contact points when using a wrench or socket, making it suitable for high-torque applications. Flange: Like other flange bolts, it may have a built-in flange under the head. The flange provides a larger bearing surface, which helps distribute clamping forces, resist loosening due to vibration, and protect the underlying material. High-Strength Materials: 12-point flange screws are often made from high-strength materials, such as alloy steel, to handle heavy loads and high torques. These fasteners are commonly used in industries like automotive, aerospace, and heavy machinery, where precise torque application is critical, and where access to the fastener may be limited, making the multiple contact points of the 12-point head advantageous.
