Hex Flange Bolts

Hex flange bolts, also called frame bolts and washer bolts, are a type of fastener with a hexagonal head and a wide flange, a flat, circular disc under the head. This flange helps distribute the load while reducing the risk of the bolt loosening over time, making hex flange bolts ideal for applications requiring high strength and vibration resistance. Hex flange bolts are commonly used in manufacturing, construction, and engineering applications. Hex flange bolts are typically used in conjunction with hex nuts to create a strong and secure fastening solution.

Applications for Hex Flange Bolts & Screws

Because hex flange bolts feature a built-in flange that acts as a weight-distributing washer, these bolts are able to bear high load levels. Common applications for hex flange bolts include securing engine components, mounting heavy machinery, and attaching panels or structures to buildings. They are often used in machinery, engines, and other heavy-duty equipment, where the bolts need to be tightened to a high torque to secure the components together. They are also used in construction applications, including large structures requiring high strength and durability.
