Abstract
A metallic head of a fastener includes merlon portions between crenel portions. The crenel portions form a slot which may be used to tighten or loosen the fastener. An insulating material covers portions of the metallic head to prevent human contact with the metallic head and terminal lugs secured thereby. The metallic head defines a counter bore portion. Inner walls of the counter bore portion may be formed into a hexagon. The insulating material may extend into the counter bore portion covering the inner walls, as well as the surfaces of the crenel portions. The bottom of the counter bore may remain uncovered to facilitate signal testing with a test probe.
