Imperial Socket Button Head Captive Screws.

What are Imperial Socket Button Head Captive Screws?

Accu's imperial socket button head captive screws are precision-engineered fasteners designed to secure components in place while preventing them from falling out once removed.

Along with imperial threads, these imperial captive screws feature a distinctive button-shaped head, providing a smooth and low-profile finish. The hex socket drive within the head allows for secure and reliable torque application, ensuring that the screw can be tightly fastened without the risk of cam-out which in turn prevents the head from becoming stripped over time.

The key attribute that sets these screws apart is their captive nature. A section of the shank is unthreaded, allowing the screw to be installed into a housing or panel where it can rotate freely without being fully removed. This design ensures that components remain attached during maintenance or disassembly, reducing the risk of losing critical parts in complex assemblies.

How Imperial Socket Button Head Captive Screws Work

Imperial socket button head captive screws are versatile fasteners that find applications across various industries, from aerospace to consumer electronics. Their primary function is to hold components together while allowing for partial disassembly without losing the screws. For instance, in the assembly of electronic devices, these screws are used to secure access panels, enabling easy access for repair or upgrades without the risk of misplacing the screws.

In the aerospace industry, where safety and precision are paramount, these screws play a crucial role in securing panels and components that may need to be accessed regularly for maintenance. The captive design ensures that the screws remain attached to the panel even when fully unscrewed, preventing them from falling into critical areas of machinery or aircraft interiors. When installed, the button head captive screw creates a robust and reliable connection, ensuring that the assembly remains intact under various operating conditions.

Material Imperial Socket Button Head Captive Screws Are Made From

At Accu, our imperial socket button head captive screws are made from A2 stainless steel, a material well known for its reliable corrosion resistance and excellent durability. A2 stainless steel is well-suited for a wide range of project applications, particularly in environments where the screws may be exposed to typical levels of humidity or moisture. This makes it an ideal choice for both indoor and sheltered outdoor uses, such as manufacturing equipment, electronic devices and general-purpose machinery.

For projects requiring an aesthetic or specific functional finish, we offer these screws in a Matte Black finish, known as AccuBlack, which provides a sleek, non-reflective appearance ideal for high-visibility or stealth applications. Additionally, we provide a thread-locking finish, AccuLock, which enhances the screw's resistance to vibration and loosening by pre-applying a thread lock patch, making it perfect for high-vibration environments such as automotive or aerospace applications.

Size and Type Imperial Socket Button Head Captive Screws Available

Our imperial socket button head captive screws are available in a range of sizes to accommodate various engineering application needs. The lengths available range from 3/8" to 3", allowing for both compact and more extended fastening requirements. Thread sizes range from 10-24 to 3/8-16, offering versatility for different load-bearing capacities and material thicknesses.

These screws feature a button head type, providing a smooth, rounded surface that reduces the risk of snagging or damage to surrounding components while still offering a wide load-bearing surface. The hex socket drive type is designed for use with standard hex keys or Allen wrenches, ensuring ease of installation and removal even in tight spaces.

In addition to our imperial socket button head captive screws, we also offer a full range of metric captive screws. This range provides additional head styles and fastening options for more specialised applications while maintaining the same high standards of precision and reliability.

FAQs

Q: Can imperial socket button head captive screws be reused?

A: Yes, our imperial socket button head captive screws can typically be reused. However, it's important to inspect the screws for any signs of wear or damage, such as thread deformation, before reusing them to ensure the integrity of the assembly.

Q: What tools are required to install imperial socket button head captive screws?

A: These screws are designed with a hex socket drive, which means they require a hex key or Allen wrench for installation. The specific size of the hex key needed will depend on the thread size of the screw but all of this information is provided in the tech spec of each and every component we sell.

Q: Are imperial socket button head captive screws suitable for high-vibration environments?

A: Yes, our imperial socket button head captive screws are suitable for high-vibration environments, especially when paired with our thread-locking finish, AccuLock. This finish enhances the screw's resistance to loosening due to vibration, making it ideal for applications in automotive, aerospace or machinery where vibration is a concern.
