This standard covers requirements for the carriage bolts, machine bolts, double-arming bolts, double end bolts and nuts used in overhead line construction. A need exists for a standard indicating the basic dimensional and performance requirements for the above bolts and nuts used on overhead lines. New IEEE Standard - Superseded. The requirements for inch-based carriage bolts, machine bolts, double-arming bolts, and double-end bolts and nuts, commonly used in overhead line construction and where the applied load is primarily a tensile load, are covered.
