Socket screws are typically made from steel or stainless steel, and come in a variety of sizes and lengths. They are often used in applications where a flush, low-profile fastener is needed, or where access is limited, such as in electronics, machinery, and furniture assembly.

One advantage of socket screws is that they provide a more secure and stable connection than traditional screws, as the hex socket allows for more torque to be applied during tightening. They are also less likely to strip or round off than Phillips or flat head screws.

Socket screws are available in a range of head types, including button head, flat head, and socket cap head, each with their own specific applications and advantages. They are commonly used in combination with nuts or washers to secure two or more objects together.
