Product Description
Hexagonal flange bolts have a hexagonal head similar to standard hex bolts, but they feature an integrated flange or washer that spreads the load and provides a larger bearing surface.
Characteristics:Head Design: The hexagonal head allows for easy installation with standard wrenches or sockets.
Flange: The flange acts as a built-in washer, distributing the load and reducing the risk of damage to the material being fastened.
Material: Commonly made from steel, stainless steel, or alloy materials, offering various strengths and corrosion resistances.
Thread Type: Available in both metric and unified thread standards.
Finish: Can come with various coatings for corrosion resistance, such as zinc plating or black oxide.
Characteristics:
Load Distribution: The flange distributes the load more evenly than a standard bolt, reducing the risk of surface damage.
Eliminates the Need for Separate Washers: The integrated flange provides a washer-like effect, simplifying assembly and reducing the number of parts required.
Improved Stability: Helps to prevent loosening over time due to vibration or movement.
Application:
Countersunk bolts are used in a variety of applications where a flush surface is needed.
Automotive: Often used in vehicle assemblies where vibration and load distribution are critical.
Construction: Used in structural applications where the flange helps to spread loads and reduce material damage.
Machinery: Ideal for machinery parts that require strong, stable connections and reduced maintenance.
Aerospace: Used in aerospace applications where load distribution and reduced parts are essential.
Furniture and Equipment: Common in situations where ease of assembly and a clean appearance are desired.
Hexagonal flange bolts combine the functionality of a hex bolt with the advantages of an integrated flange, making them ideal for applications where load distribution, stability, and ease of assembly are important.
