Secure your D-sub connection with this thumb screw by FCT from Molex. It's a compact locking mechanism that keeps D-sub contacts held firmly in place. A closely knitted UNC 4-40 thread size guarantees a tight fit that won't loosen over time. Install the thumb screw into the gaps beside your D-sub connectors to protect your connection against jostling and shocks. By screwing directly into your connectors, it provides a tight lock that's suitable for appliances with limited space.

• Durable nickel-plated brass body material is corrosion-resistant for reliable use in humid environments
• Knurled head lets you tighten the thumb screw by hand, for simple tool-free installation

• PCBs
• Mains power distribution
• Telecommunications industry

Without additional security, friction is the only force that keeps a D-sub connector in place. If any electrical contacts accidentally disconnect, it could disrupt your circuit. Using a locking mechanism like this thumb screw eliminates the risk of disruption from contact separation.
