4.5mm Round Female-Female Standoff

A Standoff is a fastener that is used to create space between two objects, often to properly position them. In the world of electronic components and electronic hardware, standoffs are typically used to space circuit boards, panels, doors or gears. Standoffs can be round, hexagonal or square in shape. They can have exterior knurling as well as swage characteristics. Female-Female or Double Female Standoffs can be fully threaded or partially threaded on each end. Male-Female and Male-Male Standoffs are more fully detailed in their own listings. Standoffs are available in a variety of materials including aluminum, brass, plastic, steel and stainless steel.
