Flange Head Bolts Manufacturer and Supplier

Flange Head Bolts, Flange Head Bolts Manufacturer, Flange Head Bolt Exporter

Ananka Fasteners Pvt. Ltd., an ISO-certified fastener manufacturing company, takes pride in offering high-performance Flange Head Bolts tailored for demanding industries. As a prominent manufacturer and exporter, we are excited to expand our global footprint with newly established offices now operational in the USA and the UK.

Flange Head Bolts are specialized fasteners characterized by an integrated flange beneath the head, which acts like a washer to distribute load over a larger surface area. These bolts are engineered to provide a secure grip, reduce the risk of damage to connected components, and enhance clamping force, making them an ideal choice for high-stress applications.

We are also in the advanced stages of achieving Aerospace and API certifications, reflecting our commitment to meeting the most stringent international standards across specialized sectors.

What are Flange Head Bolts?

Flange Head Bolts are uniquely engineered with an integrated washer-like flange beneath the bolt head, which helps distribute the load evenly and removes the need for a separate washer. Their design ensures high clamping force, vibration resistance, and ease of assembly, making them ideal for mission-critical environments.

Head Types Available

• Hex Flange Head
• Serrated Flange Head (for vibration resistance)
• 12-Point Flange Head (mainly in aerospace and automotive)
• Low Profile Flange Head

Key Features of Flange Head Bolts
