Integrated Flange Design
The built-in flange acts as a washer, increasing the contact area between the bolt head and the fastening surface. This helps distribute clamping force more evenly and reduces surface damage during installation.

Product Overview
Product Application
IFI 111 Hexagon Flange Bolts are high-performance flange fasteners manufactured according to the standards of the Industrial Fasteners Institute (IFI). Combining a hexagonal head with an integrated flange washer, these bolts provide increased bearing surface, improved load distribution, and enhanced resistance against loosening.
Designed for demanding industrial applications, IFI 111 flange bolts eliminate the need for separate washers while improving installation efficiency. They are widely used in automotive, machinery, construction, and equipment assembly where reliable fastening performance and consistent quality are required.
Draw
Specification
IFI 111 Hexagon Flange Bolts vs Standard Hex Bolts
-
Larger Bearing Surface
Unlike standard hex bolts that require a separate washer, flange bolts include an integrated flange that increases the contact area and improves load distribution.
-
Faster Assembly Process
The all-in-one design reduces the number of components required during installation, improving assembly efficiency and reducing labor costs.
-
Better Performance Under Vibration
The flange structure helps maintain joint stability in applications exposed to vibration, making it more reliable for automotive and machinery applications.
Product Advantages
Enhanced Loosening Resistance
The flange structure improves joint stability by increasing friction and maintaining consistent preload, making these bolts suitable for applications exposed to vibration and dynamic loads.
Efficient Installation Solution
By combining the bolt head and washer function into one component, IFI 111 flange bolts simplify assembly processes, reduce installation time, and lower component inventory requirements.
