Frequently asked questions
What is the difference between male-female and female-female spacers?
A male-female spacer has an external threaded stud at one end that screws into a mounting hole, while a female-female spacer has internal threads at both ends and takes a bolt on each side.
How do I install it on a mounting plate?
Screw the male stud into a threaded hole or plate, then place the board over the female end and secure it with an M3 bolt. Do not overtighten, to protect the copper threads.
