Do all pole line fasteners have an added semi-cone point?

Pole line fasteners, such as machine bolts, washer head bolts, double arming bolts and double end bolts, often have an added semi-cone point on the threaded end of the bolt. This is to provide easy installation into a wooden member without the threaded end of the bolt getting snagged on the wood. According to IEEE Standard C135.1-1999, “Machine bolts and double arming bolts that are 1/2″, 5/8″ and 3/4″ in diameter and are 8″ in length or longer shall have semi-cone points.” Larger diameters may require semi-cone points as well as bolts shorter than 8″, depending on the application. There are some configurations of pole line hardware which do not need a semi-cone point added, such as A325 structural bolts, bent bolts, and clamp rods.
