3 Types of Flange Bolt and Their Uses

Flange Bolt

If you’re in the market for flange bolts, then one of the first things you’ll need to know is what type of flange bolt is right for your application. There are several different types and sizes of flange bolts available, so understanding which type works best for your project is essential. This blog post will provide an overview of the different types of flange bolts and their uses, allowing you to select the right type for your needs.

Types of Flange Bolt

Socket Head Flange Bolt

Socket head flange bolts are used when a higher clamp load is needed than can be achieved with a standard hex bolt. The socket head design allows the fastener to be driven into place with a wrench or driver bit instead of using a tool like a ratchet or Allen key. Socket head flange bolts are commonly used in applications with limited access space, such as automotive engine compartments, machinery and equipment, and other tight spaces.

Round Head Flange Bolt

Round-head flange bolts provide a larger surface area than socket-head bolts and are often used when more torque must be applied during installation or removal. These flanges are also known as ‘button’ heads due to their round shape, making them easier to tighten by hand if necessary. Round head flanges tend to have a lower profile than socket head styles, making them ideal for use in applications where low-profile fasteners are needed, such as in furniture assembly or electronics manufacturing.

Flat Head Flange Bolt

Flat head flanges feature a flat surface on top that helps distribute the load evenly over a wider area than other types of fasteners. They are commonly used in applications that require tamper-resistant fasteners or where flush-mounting is desired, such as equipment panels or doors. Flat-head flanges have slimmer profiles when compared to round heads, allowing them to fit into tighter spaces while still providing adequate strength and stability.


Whether you need high clamp loads, tamper-proofing, flush mounting capabilities, or something else entirely – there’s sure to be a type of flange bolt that meets your needs! By taking the time to understand the various types and sizes available, you can make an informed decision about which type will work best for your application. With so many options on the market today, it’s never been easier to find exactly what you need!
