THE KLING BOLT It is claimed that the Kling bolt is the only one that will al-low the head to pass through a hole of the same diameter as thestem and still give a firm anchorage for the head on the oppositeside of the material through which it passes. To accomplishthis the bolt is split, as shown by the illustration, but as thearea of the metal at the head is greater than that at the root ofthe thread the tensile strength is not affected. It is also claimed. The Klinq Bolt. that the process of heading the bolt does not destroy the fiberof the metal. The bolt is made either with plain head or bracedhead, the latter being designed for use where heavy strains type of bolt is adapted for hollow construction of the illustrations shows the use in attaching brackets, etc.,to piping used for a railing, and it is similarly adaptable forswivels, loops, attachments for guy wires, etc. Where gates are
