Imperial Socket Head Cap Captive Screws.

What are Imperial Socket Head Cap Captive Screws?

Imperial socket cap head captive screws are precision fasteners designed according to imperial measurements. Featuring a cap head with a hexagonal socket drive, they allow for high torque and secure fastening. The captive screw design ensures the screw remains attached to a panel or assembly even when loosened, enhancing safety and preventing loss of components in sensitive environments. This is achieved through an unthreaded section beneath the head that meets industry standards for captive hardware.

How Imperial Socket Head Cap Captive Screws Work

These screws are essential in applications requiring frequent assembly and disassembly, such as machinery maintenance, aerospace equipment and electronics enclosures. For instance, in industrial machinery, captive screws prevent loss during maintenance, allowing personnel to access internal components without misplacing fasteners as they can be loosened yet still stay attached to the panel. The hex socket drive enables precise tightening with an Allen key, ensuring consistent torque and reducing the risk of over-tightening that could damage threads or components.

Materials Imperial Socket Head Cap Captive Screws Are Made From

Our imperial cap head captive screws are crafted from high-quality A2 and A4 stainless steel. A2 offers excellent corrosion resistance, ideal for general indoor applications. A4, or marine-grade stainless steel, provides superior resistance to chemicals and saltwater, making it perfect for marine, chemical processing and outdoor use. Selecting the appropriate material ensures longevity and reliability in specific environments.

Size and Type Imperial Socket Head Cap Captive Screws Available

Accu offers a wide range of sizes to meet various engineering needs, with thread sizes from 0-80 UNF to 1"-8 UNC and lengths from 1/4" to 12". Each screw features a cap head design with a hex socket drive for ease of use and consistent torque application. Along with the standard untreated finish, we also offer specialist finishes are available such as AccuBlack chemical blackeneing which provides a sleek matte black appearance for aesthetic purposes or to reduce reflections in sensetive equipment. We also offer AccuLock thread locking patches pre-appled which prevents loosening due to vibration, essential for machinery and automotive uses.

In addition to imperial sizes, we also offer metric socket cap head captive screws for projects requiring metric measurements.
