1.Products Details:
Hexagon socket button head screws, also known as socket cap screws, are a type of screw widely used in mechanical and industrial applications. They are characterized by a rounded head with a hexagonal socket on the top, which allows for precise torque application using a hex key.
Structure and Design
• Head: The button - like head provides a smooth and rounded surface, which is aesthetically pleasing and also helps prevent damage to adjacent components or surfaces. It has a recessed hexagonal socket that enables the use of a hex - shaped tool for driving the screw.
• Shank: The shank of the screw is typically cylindrical and threaded along its length. The thread design can vary depending on the application, with common thread types including metric and imperial threads. The shank diameter and length are available in a wide range of sizes to meet different fastening requirements.
