Flange Bolt – Strong and Secure Fastening Solution
Flange bolts are a type of fastener with an integrated washer-like flange under the head. They provide a larger bearing surface, which helps distribute pressure more evenly, making them ideal for applications requiring a secure and durable connection.
Key Features of Flange Bolts
Built-in flange – Acts as a washer, reducing the need for separate washers.
High-strength fastening – Designed to withstand heavy loads and vibrations.
Variety of materials – Available in stainless steel, galvanized steel, and titanium.
