Hex socket button head screws are a type of screw that has a cylindrical head with a flat top and a hexagonal recess or socket in the center. They are often used in applications where a smooth, low profile screw head is desired, such as in furniture assembly, electronics, and machinery.

The function of hex socket button head screws is to securely fasten two or more objects together. The hexagonal socket provides a means for tightening and loosening the screw using a hex key or Allen wrench, which provides better leverage than traditional screwdrivers and reduces the risk of damaging the screw or the surrounding material.

Unlike traditional flat head screws, which can easily strip or become damaged when subjected to high torque, hex socket button head screws distribute force evenly across the head, making them less likely to strip or deform. This makes them a popular choice for applications that require high strength and durability.

Hex socket button head screws serve an important function in a wide range of industries and applications, providing a reliable and secure means of fastening components together.
