1. A security fastener assembly comprising:
a cap having a metallic cap body with a tool bearing surface and a threaded attachment portion formed opposite the tool bearing surface;
a fastener body having a mating threaded attachment portion and tapered bearing surface integrally formed at a first end along which the cap is secured, and a keyed security feature formed adjacent the mating threaded attachment portion, wherein a second end of the fastener body has a threaded engagement portion for securing the security fastener assembly to a vehicle,
wherein the fastener body has a first thread dimension of the mating threaded attachment portion being different than a second thread dimension of the threaded engagement portion, wherein a first break-away torque between the cap and the fastener body based on the first thread dimension is less than a second break-away torque between the fastener body and the vehicle based on the second thread dimension,
wherein the mating threaded attachment portion of the fastener body is installed with rotation in a first direction by a standard tool contacting the tool bearing surface of the cap thereby rotating the cap and fastener body in the first direction, and
wherein engaging the tool bearing surface of the cap and rotating in a second direction opposite the first direction does not rotate the mating threaded attachment portion of the fastener body, and
wherein the fastener body is removable with the keyed security feature.
