RS PRO Standoff, M4 x M4 Thread, 20mm Body, Steel, Female/Female

From RS Pro a range of robust, high-quality hexagonal shaped standoffs made from zinc plated mild steel with a metric internal thread or threaded stud on either end. These versatile standoffs are designed to securely mount your PCB as well as elevating it from other components such as the inside of a computer chassis or another PCB. They are also ideal for improving airflow space around components when the equipment becomes hot. These stand-offs are available in a range of different heights and threads sizes to suit a wide range of PCB applications

What are Threaded Standoffs?
Standoffs are used to separate a PCB by a set distance from other components or a base board serving a similar function as spacers. These standoffs are available with male-female or female-female configurations to suit a wide range of PCB applications. The female-female has an internal thread either end. The male-female has an internal thread one end and an external threaded stud or screw the other to enable components to be joined together.

Features and Benefits
• Versatile and easy to fit
• Hexagonal design allows tightening with a wrench
• Lock PCB securely into place
• Mild steel material for mechanical strength and resistance to high-temperature environments. Metal standoffs also keep electrical conductivity when looking to maintain a circuit
• Zinc plating for resistance to oxidation and corrosion

Questions and Answers

How do the Standoffs Fit Together?
The correct size standoff is selected and inserted into or aligned with pre-drilled holes in the PCB. A metric screw or a nut is then fastened onto or into the thread of the standoff to lock and hold it securely in place. The nuts and screws can be released and retightened as required. A male standoff can be screwed into a female standoff providing the threads are the same size.

Where are these Standoffs used?
These standoffs are used in various electronic applications for creating spacing between individual PCBs where they act as spacers and to separate PCB boards from other components. The mild steel construction of these stand-offs means they are ideal for use in applications where high mechanical strength is required and in high-temperature environments. These applications range from consumer electronics and office machinery to datacoms and telecommunications equipment.

Threaded spacers have same thread size at both ends.
