Modern Design Hexalobular Head Flange Bolts are commonly used in the manufacturing of automobiles, especially in parts such as engines and chassis. Their star-shaped heads can distribute force more evenly than ordinary hexagonal bolts, thereby reducing the possibility of damaging the heads. The built-in nut design eliminates the need for separate washer assembly, significantly speeding up assembly efficiency. Since high-vibration areas such as suspension systems require strict tightness, this product can perform well in such scenarios. You will find that these bolts are used in various vehicles ranging from ordinary cars to large trucks, helping to keep vehicles sturdy and reliable over time, even in harsh conditions.
The Modern Design Hexalobular Head Flange Bolts have distinct features: their heads have a hexagonal star-shaped driving structure (commonly referred to as "hexagonal star-shaped threads"), while their bottoms have an embedded flange, which functions similarly to an internal washer. This flange usually has fine tooth-like structures, which help prevent loosening during tightening.
These bolts come in various lengths and thread sizes, ranging from the small M3 size to M20. Its outstanding characteristics of high strength and excellent precision make it an ideal solution for fields where conventional hexagonal bolts may not be suitable (such as automobile manufacturing and heavy machinery assembly).

Q:What are the key advantages of Modern Design Hexalobular Head Flange Bolts compared to standard hex bolts?
A: The Modern Design Hexalobular Head Flange Bolts have significant advantages. Their star-shaped transmission structure can more evenly distribute the force during tightening, which helps prevent loosening and reduces tool wear. Its effect will be particularly significant for scenes such as automobiles and heavy machinery that are in high-vibration conditions for a long time. The hexagonal head flange bolts have significant advantages. Their star-shaped transmission structure can more evenly distribute the force during tightening, which helps prevent loosening and reduces tool wear. Its practicality will be fully demonstrated when applied to environments with strong vibrations such as automobiles or heavy machinery.
The built-in flange design means you don't need to additionally equip with washers, thus speeding up the installation process and ensuring the fixture is stable and evenly distributed. These features combined make these bolts an efficient choice for critical parts - they can maintain the fastening state and help maintain the strength of the connection point over the long term.
