Hex flange bolts are among the most versatile and widely used fasteners in the industrial world, known for their built-in washer-like flange that distributes load efficiently and eliminates the need for a separate washer. As a trusted manufacturer and supplier of hex flange bolts, we deliver high-performance, corrosion-resistant, and precision-engineered fasteners tailored to suit diverse applications across global industries.
What Are Hex Flange Bolts?
Hex flange bolts are hexagonal head bolts with an integrated flange at the base of the head. This flange acts as a washer, spreading the clamping load over a larger surface area. It reduces the risk of damage to the fastening material and enhances bolt retention, especially in high-vibration environments.
These bolts are frequently used in the automotive, aerospace, oil & gas, heavy machinery, and construction sectors for their strength and reliability.
Design & Prototyping
Whether you need a bolt designed for extreme environments or specialized machinery, our engineering team can prototype the fastener to your exact specifications, including:
Flange diameter customization
Thread pitch variation (coarse/fine)
Head height and drive type
Unique surface treatments or alloy choices
Our focus is on innovative fastening solutions to meet modern engineering demands.
Rapid Manufacturing Capabilities
Thanks to our state-of-the-art CNC machines, forging units, and automated plating lines, we support rapid manufacturing of hex flange bolts, from small-batch custom orders to bulk production runs.
We maintain large inventories of standard sizes and provide just-in-time delivery across various industries and countries. Our agile manufacturing approach ensures minimal lead times and consistent quality.
Custom Coating & Plating Options
Corrosion resistance and environmental compatibility are crucial for bolt longevity.
Zinc and yellow zinc plating
PTFE (Teflon) coating
Hot-dip galvanizing
Black oxide finish
Dacromet and Geomet coatings
Nickel, chrome, and copper plating
These coatings enhance performance in aggressive conditions like marine, chemical, offshore, and automotive applications.

FAQs
What materials are hex flange bolts made from?
They are typically manufactured from stainless steel, alloy steel, titanium, and specialty alloys like Inconel and Monel.
Are hex flange bolts reusable?
Yes, if not overtightened or damaged, they can be reused. However, it depends on the application and environmental conditions.
Do I need a washer with a hex flange bolt?
No, the integrated flange serves the same purpose as a washer, distributing the load and preventing loosening.
