Abstract: A fastener is provided for splicing end portions of conveyor belts together with the fastener having a bolt with a pilot or lead-in portion that provides improved threading of a nut thereto and makes installation of the fasteners on the belt ends faster and easier. The pilot of the bolt is longer than the beveled conical tip portion of prior bolts so that nuts received thereon will stay substantially aligned with the axis of the shank. In this manner, threading of the nut to the bolt shank is easier in terms of avoiding cross-threading problems. Also, as the pilot portion of the shank is free of any threads, the installation of the bolt onto the belt ends can be done more quickly with less resistance during the insertion process.
