Sealed at the top to prevent debris from getting inside and making them seize up, these guide pins are a good choice for machining fixtures. As the workpiece pushes against the pin head in one direction, the internal spring pushes back to hold it in place for clamping. Press into a drilled hole using the installation tool (sold separately).
