Slotted Track Bolts, Ribbed Neck
Slotted track bolts with ribbed necks are a round head bolt with a slot that extends across the center of the top of the head for driving. Directly below the head, the shoulder has vertical ribs that protrude out from the screw's shank, giving that section a greater diameter than the threaded portion of the fastener. Slotted track bolts are designed specifically for use in the installation of garage doors.
