Abstract
A security fastener has a threaded body with tool engaging surfaces. It is surrounded by a freely rotatable spinner. When the fastener is tightened down the tool engaging surfaces are removed so there is nothing on the fastener to be engaged by a tool. The side of the fastener is shielded by the rotatable spinner.
