Abstract
A tamper-resistant fastener for use on utility meter collars. The fastener is used with standard utility meter equipment and prevents significant rotation of a collar takeup ring screw in either the threading or unthreading direction. Once one form of the tamper-resistant fastener is in place, the meter collar can only be removed by authorized personnel. In another form of the fastener, removal is apparent.
