Hexagon socket head screws, also known as Allen screws or Allen bolts, are a type of fastener commonly used in various applications. They are characterized by a cylindrical head with a hexagonal recess in the center, designed to be tightened or loosened using an Allen wrench or hex key.

The primary function of hexagon socket head screws is to securely fasten two or more objects together. They offer several advantages over other types of screws. Firstly, the recessed hexagonal socket allows for a greater torque to be applied, resulting in a tighter and more secure fastening. This makes them suitable for applications where high torque is required, such as machinery, automotive, and construction.

The hexagonal shape of the socket head provides better resistance to stripping or rounding off compared to other screw types, such as Phillips or flathead screws. This makes hexagon socket head screws less prone to damage during installation or removal.

Hexagon socket head screws are available in various materials, including steel, stainless steel, and titanium, providing options for different strength requirements and corrosion resistance. They come in a range of sizes and lengths to accommodate different applications.

The function of hexagon socket head screws is to provide a reliable and secure fastening solution in a wide range of industries and applications, ensuring the stability and integrity of assembled objects.
