A meter box ground clamp may include a body portion having a first portion, a second portion, and a gripping portion that is configured to extend from the second portion and a fastener member configured to couple the body portion to an electrical meter box. The fastening member may be configured to extend through a receiving portion of the first portion to engage a first surface of the meter box so as to move the first portion away from the first surface of the meter box and move the gripping portion into engagement with a second surface of the meter box that faces away from the first surface of the meter box, and the receiving portion may be configured to receive the fastener member at a first angle less than 90 degrees relative to a plane of the first portion such that a free end of the fastener member forms a second angle greater than zero degrees relative to the second surface of the meter box. The second angle may be configured to create a force that urges the second portion of the body portion toward the meter box in response to a tightening torque applied to the fastener member so as to prevent the body portion from moving off the meter box in response to the tightening torque.
