Product Details
DIN7380 M3-M16 Carbon Steel Pan Head Hex Socket Machine Screws
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.
2.Key Features:
Good Appearance
- They have a smooth and rounded head, which can provide a more
aesthetically pleasing appearance, especially in applications where
the appearance of the product is important.
High Strength
- The hexagon socket design allows for a more efficient transfer of
torque, enabling the screw to be tightened to a higher torque level
without stripping the driving recess. This results in a more secure
and reliable connection.
Space - saving
- The round head of the screw is relatively small in size, which can
save space in some applications where space is limited
Easy Assembly
- With the use of a hexagon socket wrench, the installation and
removal of the screws are relatively convenient, which can improve
the efficiency of assembly and disassembly.
Wide Application
- They are suitable for a variety of materials and applications, such
as in the assembly of machinery, electronics, furniture and other
industries.
