4.5mm Hex Male-Female Standoff

A Metric 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. Metric standoffs can be round, hexagonal or square in shape. They can have exterior knurling as well as swage characteristics. Metric Male-Female Standoffs have internal threads on one end and male threads on the other. Metric Female-Female or Double Female Standoffs can be fully threaded or partially threaded on each end. Standoffs are available in a variety of materials including aluminum, brass, plastic, steel and stainless steel.
