Hexagon Flange Bolt

Hexagon Flange Bolt Overview

The Hexagon Flange Bolt (also known as a bolt hex flange head) is a specialized one-piece fastener that eliminates the need for a separate washer. It features a hexagonal head with an integrated circular flange at the base. This design distributes the clamping load over a larger surface area, preventing damage to the mating surface and significantly increasing resistance to loosening caused by vibration.

Our Hexagon Flange Bolts are high-strength fasteners engineered for applications requiring superior clamping force and vibration resistance. They includes a wide range of fasteners designed to meet global standards (such as GB5789, DIN 6921, and ISO 4162). Whether you require a standard carbon steel bolt or a corrosion-resistant Stainless Steel Hex Flange Bolt (304 or 316 grades), we provide solutions that ensure a secure, maintenance-free connection for automotive, marine, and industrial machinery.

FAQ:

Q1: What is a Hexagon Flange Bolt?
A: A Hexagon Flange Bolt is a type of hex head bolt with a built-in flange that distributes the load more evenly, reduces the need for a separate washer, and improves fastening stability.

Q2: What is the difference between a standard hex head bolt and a Hexagon Flange Bolt?
A: A standard hex head bolt typically requires a separate flat or lock washer to prevent damage and loosening. A Hexagon Flange Bolt has this washer integrated into the head design, offering better efficiency, higher strength, and faster installation.

Q3: Do you offer serrated and non-serrated flange bolts?
A: Yes. We supply both non-serrated (smooth) flanges for general load distribution and serrated flanges, which “bite” into the surface to provide extra locking power against vibration.

Q4: Can I get custom sizes for my Stainless Steel Hex Flange Bolt order?
A: Absolutely. While we stock standard sizes (M5 – M20), we can manufacture custom dimensions and specific thread lengths to meet your unique project requirements.
