Captive Screws for Secure & Convenient Fastening

Why Use Captive Screws?

Captive screws are electronic hardware screws that feature a unique design that keeps them from falling off a circuit board or component, even when loosened. They allow for quick and easy installation and removal without worry that a screw will fall. They are available in a wide range of sizes and styles to match any application. Key advantages of captive screws include:

·         Reduced risk of losing loose screws during assembly or disassembly

·         Increased efficiency due to quick and easy fastening design

·         Allow for simple reinstallation without full removal of screws

·         Available in high-performance materials, including materials with electronic conductivity like brass

Common Applications & Industrial Uses for Captive Screws

Electronics & PCBs

Captive screws are used in the electronics industry for printed circuit boards (PCBs). In these contexts, space is often limited. Captive screws' ability to remain securely attached to the panel eliminates the risk of standard small screws getting lost during assembly. They provide a perfect solution for quick and easy access while eliminating the risk of losing the fasteners.

Industrial Machinery

Captive screws are also used in a wide range of industrial machinery and equipment, particularly in industrial components that require frequent maintenance. Captive screws provide simple access without the hassle of handling loose fasteners. These screws are often utilized in industrial equipment where downtime needs to be minimized. Their ability to stay in place saves time during disassembly and reassembly.

Medical Devices

In medical devices, captive screws are used to ensure secure and safe fastening in equipment where loose parts could lead to malfunctions or safety risks. Their design allows for better efficiency during assembly and disassembly, and supports the strict regulatory requirements of the medical industry.

Telecommunications & Aerospace

Telecommunications and aerospace applications require fastening solutions that can withstand extreme conditions. Captive screws provide a reliable solution against vibration, temperature fluctuations, and environmental factors that can otherwise jeopardize fastening reliability. They offer secure fastening for equipment exposed to the elements or high altitudes.
