Female Hex Circuit Board Standoff: #4-40, 2" OAL, 3/16" Width Across Flats MPN:P405M03F21440

Female hex standoffs are used to mount printed circuit boards (PCBs) onto a substrate or to each other in electronic equipment's design assemblies, providing mechanical support while allowing electrical continuity between components mounted on the board. These screw-down stand offs have #4-40 threads suitable for use with soldered plated through holes and can be used alongside nuts at either end or a spring-cage system as an alternative installation option. As part of PCB assemblies, female hex standoffs are common in applications such as computers, mobile phones, medical equipment and consumer electronics across industries where proper alignment, conductivity, and secure fixing methods are crucial for reliability, performance and durability of the product or device being built.
