Types of Small Head Machine Screws
Low-Profile Head Screws
Low-profile head screws feature a shallower head, which allows for a more streamlined appearance. They are often used in electronics and appliances where space is at a premium. Their design helps to minimize snagging and provides a more finished look.
Flat Head Machine Screws
Flat head screws are characterized by their flat tops and conical shape, allowing them to sit flush with the surface. This type of screw is commonly used in woodworking and metal fabrication, providing a clean finish and reducing the risk of injury from protruding heads.
Pan Head Machine Screws
Pan head screws have a rounded head with a flat bearing surface, making them easy to drive. They are versatile and can be used in various applications, including automotive and industrial machinery. Their design allows them to distribute load evenly.
Socket Head Screws
Socket head screws, featuring a hexagonal drive, are designed for high-stress applications. Their design provides excellent torque capabilities, making them ideal for machinery and heavy equipment. Socket head screws are commonly made from alloy steel for added strength.
Button Head Machine Screws
Button head screws have a rounded shape that provides a high-strength fastening solution while remaining aesthetically pleasing. They are widely used in automotive and furniture manufacturing due to their durability and ease of installation.
Applications of Small Head Machine Screws
