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.

Claims (8)

1. A fastener comprising:

a metallic head defining a counter bore portion and having opposing merlon portions; and

insulator material that covers an outer portion, an inner wall and a top portion of each merlon portion, wherein the insulator material defines openings that expose end portions of each merlon portion.

2. The fastener of claim 1 wherein the insulator material is a rigid material.

3. The fastener of claim 1 wherein the inner walls of the merlon portions form a shape.

4. The fastener of claim 3 wherein the shape formed by the inner walls is a polygon.

5. The fastener of claim 3 wherein the insulator material that covers the inner walls of the merlon portions forms a shape that is substantially the same as the shape formed by the inner walls of the merlon portions.

6. The fastener of claim 1 wherein the insulator material that covers the inner walls of the merlon portions forms a shape.
