Threaded mechanical fastening systems and methods are provided that allow the simple deflection of a washer to indicate that a desired minimum torque has been reached or that a desired maximum torque has been exceeded. The method includes providing a threaded connection having a washer, installing the threaded connection so that the washer is supported as a simple beam over a gap, and using an amount of deflection of the washer as a result of torque applied by the threaded connection as an indicator. The torque indicating threaded mechanical fastening system includes a threaded connection and a washer supported as a simple beam over a gap so that the threaded connection, when tightened to a predetermined torque, deflects, in bending, the washer into the gap.

An electrical connector for a composite core conductor and a method of controlling crimping thereof includes a coupling portion and a tubular portion extending from the coupling portion. A conductor has a non-metallic core surrounded by electrically conductive strands and has a connecting portion of the core extending axially beyond the strands. The connecting portion is received in the tubular portion. A crimped portion on the tubular portion radially engages the connecting portion and secures the conductor to the tubular portion. The crimped portion is formed by concave surfaces on internal surfaces of crimping dies. The concave surfaces have different radii of curvature than remaining portions of the internal surfaces.

Method of forming an electrical connector

A spring-loaded parallel pad clamp connector is provided. The clamp includes a top jaw; a bottom jaw having an eye depending therefrom; one or more springs biasing the top and bottom jaws to a closed position; and a surface positioned a predetermined distance from the eye so that the surface acts as a fulcrum and force translation surface for a lineman hot stick.

A spacer assembly includes first and second clamping bodies. The first clamping body has a first slot therein and the second clamping body has an opening. A fastener is received by the first clamping body slot and the second clamping body opening to secure the first clamping body to the second clamping body such that rotation of the fastener moves the fastener in the first clamping body slot to move the first clamping body relative to the second clamping body.

A clamp for a spacer-damper includes a first jaw and a second jaw connected to the first jaw. The first jaw has a first clamping surface and a first aperture. The first aperture retains the fastener in an initial position and in a second position spaced latterly from said initial position. The second jaw has a second clamping surface and an open-ended second aperture. The second aperture receives the fastener in the second position. The first jaw may also include a keeper surface for receiving the fastener in an initial position, a keeper pocket for receiving the fastener in a second position and a keeper protrusion is positioned between the keeper surface and the keeper pocket.

A method of spacing conductors includes positioning a conductor between a first clamping body and a second clamping body. A fastener received by the first and second clamping bodies is rotated in a first direction causing a first set of teeth associated with the fastener to engage a second set of teeth associated with the first clamping body to move the first clamping body toward the conductor.

A spring loaded parallel pad clamp connector is provided. The clamp includes a top jaw; a bottom jaw having an eye depending therefrom; one or more springs biasing the top and bottom jaws to a closed position; and a surface positioned a predetermined distance from the eye so that the surface acts as a fulcrum and force translation surface for a lineman hot stick.

A ground strap shield connection includes a body member disposed between an insulation layer and a ground shield of a first cable. The body member has a first tapered portion and a first threaded portion on an outer surface thereof. A cap member has a second tapered portion and a second threaded portion on an inner surface thereof. The ground shield of the first cable is disposed between the first and second tapered portions of the body member and the cap member when the first and second threaded portions are engaged. A ground strap has a first end connected to the cap member and a second end connectable to another ground strap of another ground strap shield connector connected to a second cable.

A spacer assembly includes first and second clamping bodies. The first clamping body has a first slot. The first slot has a first set of teeth. The second clamping body has a second slot. The fastener connects the first clamping body to the second clamping body. The fastener has a second set of teeth to engage the first set of teeth such that rotation of the fastener moves the first clamping body relative to the second clamping body.
