A clamp comprises first and second jaws with an elongate threaded member allowing threaded movement of one jaw along the member by rotation of the elongate member while allowing movement of the other jaw without regard to the threads. Clamp teeth, which may have a surface profile designed to conform to the clamped article, may be provided

The grounding clamp system is for use with an electrically insulated pole and for attachment to an electrical conductor in angled configurations. The grounding clamp system includes a clamping mechanism having an actuatable clamp and an associated ground conductor connector. An attachment coupler is configured to attach to the electrically insulated pole, and an angular adjustment mechanism is coupled between the clamping mechanism and the attachment coupler. The adjustment mechanism is configured to provide angular adjustment between the clamping mechanism and the attachment coupler in at least one axis while also transferring force to actuate the actuatable clamp when attaching the clamping mechanism to the electrical conductor at a selected angular position. The clamping mechanism is configured to create a path to pass ground fault current from the electrical conductor to a ground conductor coupled to the ground conductor connector without including the angular adjustment mechanism in the path.

Various implementations of grounding clamps and torque-controlled fasteners are disclosed. The grounding clamps may be used to attach grounding conductors to various structures, such as pipes, conduit, grounding rods etc. The torque-controlled fasteners may use various techniques to control the amount of torque applied to the fasteners used with the grounding clamps described herein.

A clamp for a male terminal of a power source, the terminal including a frustoconical body projecting out of a base surface that is part of the source against which a greatest diameter of the terminal rests, may include: at least one ring-shaped first portion, with an open section of its circumference, the at least one first portion having a first diameter such that a predetermined radial clearance exists when the at least one first portion axially fits upon the frustoconical body, the at least one first portion also having two jaws which axially project out of the circumference of the at least one first portion, the jaws being in opposed, spaced-apart relationship; and a clamping device which acts on the jaws and is configured to move the first jaws toward each other to tighten the at least one first portion around the frustoconical body with elimination of the clearance.
