Description
Flange bolts are a specialized type of fastener designed to provide a secure, uniform clamping force while simplifying assembly and improving load distribution.
A flange bolt is essentially a hex-head bolt that has an integrated washer-like flange beneath the head. This flange is typically circular and has a slightly larger diameter than the bolt head itself. The purpose of this built-in flange is to distribute the clamping load over a larger surface area, reducing the risk of damage to the bolted material and improving joint stability.
Flange bolts are designed to eliminate the need for separate washers, which simplifies assembly processes, reduces part counts, and enhances overall efficiency in fastening applications.
Applications of Flange bolts
Flange bolts are used across a wide range of industries due to their ease of use and reliability. Some of the most common applications include:
-
Automotive Industry: Flange bolts are extensively used in automotive engines, transmissions, exhaust systems, and suspensions. Their ability to withstand vibration and provide uniform clamping makes them ideal for these applications.
-
Machinery and Equipment: Flange bolts are used in heavy machinery and industrial equipment where high-strength fastening is critical. The flange design helps distribute the load evenly across surfaces like machine casings, frames, and structural components.
-
Construction and Steel Structures: Flange bolts are employed in structural steel connections, flanged joints in piping systems, and heavy-duty construction where strong, stable fasteners are required.
-
Pipeline and Flange Connections: In piping systems, flange bolts are used to secure flanged pipe sections together. They ensure a tight, leak-free seal that can withstand internal pressure, thermal cycling, and vibration.
