Abstract
A barrier head bolt for use in power feeder applications including a main bolt portion and an extended torque head portion, the torque head portion designed and constructed to shear off the main body of the bolt at a predetermined torque, and which projects above the main body portion a sufficient distance so as to inhibit or prevent the application of a joint sleeve without first shearing off the extended torque head portion of the bolt, thus ensuring that the joint is properly tightened.
