Cup Head Hexagon Socket Screws are screws with a cup-shaped head and a hexagonal hole in the bottom. This design provides greater torque output and a more secure tightening connection for applications that require a flat or decorative surface. These bolts can be installed using a hex wrench or allen key and are widely used in industries such as furniture, woodworking, automotive and machinery. Their Cup Head design provides a larger contact area, making them more secure when loads are evenly distributed. Additionally, the cup head of Cup Head Hexagon Socket Screws provides a somewhat decorative effect, making them especially popular in applications that require an aesthetically pleasing appearance.
Cup Head Design
The cup head provides a low-profile fastening option, allowing for a smooth surface finish. This design minimizes the risk of snagging, making it ideal for applications where space is limited.
Hexagon Socket Drive
The hexagon socket (or Allen) drive allows for better torque application, reducing the likelihood of stripping compared to traditional screw heads. This feature ensures a secure fit and allows for easy tightening with hex keys.
Material Variety
Cup head Hexagon Socket Screws are available in a range of materials, including stainless steel, carbon steel, and alloy steel. This variety allows for selection based on specific strength, corrosion resistance, and environmental conditions.
Surface Treatments
These screws can be treated with various finishes, such as zinc plating, black oxide, or passivation, to enhance their corrosion resistance and aesthetic appeal, suitable for indoor and outdoor applications.
High Strength and Durability
Engineered for strength, these screws are capable of withstanding heavy loads and harsh environments, making them ideal for industrial and construction use.
Wide Range of Sizes
Cup Head Hexagon Socket Screws come in various sizes and lengths, allowing for versatility in applications. This makes it easy to find the right screw for any project.

FAQ
A socket cap screw, also known as a cup head hexagon socket screw, is a type of fastener with a cylindrical head and a hexagonal drive that allows for easy tightening using a hex key.
Socket cap screws are typically made from various materials, including stainless steel, carbon steel, and alloy steel, offering different levels of strength and corrosion resistance.
To select the right size, consider the diameter, length, and thread pitch specified for your application. Always refer to manufacturer guidelines or engineering drawings.
You will need a hex key (Allen wrench) of the appropriate size, a torque wrench for tightening, and possibly a drill if pre-drilling is necessary.
Advantages include their strong clamping force, low-profile design, ease of installation and removal, and the ability to apply high torque without stripping.
Yes, socket cap screws can often be reused, provided they are not damaged or excessively worn. However, always inspect for signs of wear or deformation before reinstallation.
Torque specifications are crucial to ensure that the screw is tightened adequately without being over-tightened, which could strip threads or damage materials.
Thread locking compounds should be used in applications where screws are subjected to vibrations or dynamic loads to prevent loosening over time.
To prevent corrosion, choose screws with appropriate coatings (like zinc plating or black oxide) and consider using stainless steel for applications exposed to moisture or harsh environments.
If a socket cap screw is stripped, you can try using a screw extractor or drill it out. If the surrounding material is not compromised, replacing the screw may be necessary.
