A security device and fastener is used in a security system and method. The device has a body portion with a base, an outer surface, a cylindrical cavity and an inner radial flange defining a bolt hole that is coaxial with the cavity. The sidewall of the cavity is sized to have reduced radial clearance between a standard bolt head and a standard wrench socket to prohibit removal of the bolt except with a specially configured socket. The fastener includes this device and a nut and bolt combination. The system includes the fastener and the specialty wrench tool. The security device can be formed as part of a fixture that is adapted to secure a sign to a support, such as a post. The method includes the steps of providing a security device as disclosed, providing a specialty socket and securing a plurality of items together therewith.
