DEFINITION

Classification: 174/159

(under subclass 158) Devices consisting of a nail, staple, or similar fastening element adapted to secure one or more conductors to a wall or other supporting surface and provided with an insulating head, washer, strip or similar element for insulating the conductors.

(1) Note. Compare subclasses 157 and 166 for insulators adapted to be secured to a support by means of a nail, screw, or similar fastening element, but in which the conductor is secured to the insulator in substantially spaced relation to the supporting surface.

(2) Note. For fastening devices such as bolts, rivets, etc., having means for insulating the same from a structure penetrated by the fastening device, see this class, subclass 138.

(3) Note. For driven, headed and screw threaded fastenings, per se, not having electrical characteristics, see Class 411, Expanded, Threaded, Headed, and Driven Fasteners, or Locked or Coupled Bolts or Nuts, even though formed in whole or in part of a material having inherent insulating properties.
