The Hexagon Flange Bolt (also known as a bolt hex flange head) is a specialized one-piece fastener designed to provide superior clamping force without the need for a separate washer. Featuring a hexagonal head with an integrated circular base, these hex head bolts distribute clamping loads over a significantly larger surface area. This advanced design prevents damage to mating surfaces and provides elite resistance to loosening caused by high-vibration or heavy-duty dynamic loads.
Our collection of Hexagon Flange Bolts is engineered to meet or exceed rigorous global standards, including GB5789, DIN 6921, and ISO 4162. Available as both Full Thread bolt options for maximum grip and Half-Tooth Bolt (partially threaded) configurations for high-shear applications, these fasteners are manufactured from premium 304 and 316 stainless steel. Whether for automotive assembly, marine engineering, or industrial machinery, these hex bolts offer a reliable, maintenance-free solution for any structural project.
The built-in flange acts as a permanent washer, spreading force evenly to protect your materials and ensure a more stable connection.
The wide bearing surface significantly reduces the risk of the bolt backing off under the stress of constant movement or vibration.
By combining the bolt and washer into a single component, these fasteners simplify inventory management and allow for significantly faster installation times.
We utilize premium 304, 316, and Duplex Stainless Steel, providing outstanding protection against rust, oxidation, and harsh chemical environments.
Every hex head bolt undergoes rigorous testing for tensile strength and dimensional accuracy, ensuring you receive high-quality hardware directly from the manufacturer.
We provide both Full Thread bolt and Half-Tooth Bolt designs in sizes ranging from M5 to M20 to fit your specific engineering requirements.
