Disclosed is a security device and method. The device includes a bolt having a first hole drilled radially therein, a second threaded hole drilled axially therein to intersect the first hole, and a third hole formed axially therein connecting the second hole with the end of the bolt. A bar is insertable into the first hole to extend radially outside the bolt thereby to prevent a nut from being removed from the bolt. The bar is secured in the bolt by means of a pick-proof lock that has a screw portion threadably engagable with the second hole to engage the bar, and a lock body configured to fit the third hole.
