A brass contact screw on a tattoo machine is super conductive and allows current to run through it, while absorbing the constant hit of the returning front spring. This opening and closing can take a toll on the contact screw material. This one-piece brass contact screw has a total length of 35mm, with a thread length of 25mm and thick decorative 10mm head making it perfect for asorbing vibrations.

Each screw is sold as a single item.
