Publication number: 20230340984Abstract: Various embodiments provide a fastener including a head, a shank connected to the head and having a tip, one or more helical thread formations extending outwardly from the shank, and wherein a bottom portion of the head includes a plurality of ribs that extend towards the tip of the shank and that are shaped to abruptly frictionally engage a surface of a first object being attached to a second object to create an immediate frictional torsional resistance of a desired force level to the tightening of the fastener. This frictional resistance is provided back to the tightening tool to inform the operator of the tightening tool that the head of the fastener has sufficiently engaged the first object and that further tightening or clockwise rotation of the fastener is unnecessary.Type: ApplicationFiled: June 28, 2023Publication date: October 26, 2023Inventors: Victor Truong, Michael C. Dill, Yongping Gong, Mark D. Latz

Patent number: 11578747Abstract: Various embodiments of a fastener driveable into a substrate are provided. The fastener includes a head, a shank, and a helical thread formation. Portions of the shank and helical thread formations may be tapered. The outer diameter of the shank may decrease in a direction away from the head. An outer diameter of the thread formation may increase in a direction away from the head. The head may include a plurality of extending ribs. The helical thread formation may be formed with a plurality of grooves that are respectively each partially defined by a straight cutting edge. These improvements reduce torsional failure of the fastener from over tightening.Type: GrantFiled: February 19, 2020Date of Patent: February 14, 2023Assignee: Illinois Tool Works Inc.Inventors: Yongping Gong, Victor Truong, Stanley J. Cabaj, Mark D. Latz, Michael C. Dill

Patent number: 10641311Abstract: A fastener including a body having a threaded portion and an opposing, tapered portion, where the tapered portion includes an outwardly angled surface, and a sleeve movably connected to the body. The sleeve includes a plurality of fingers at least partially separated from each other, where each of the fingers includes at least two, axially spaced gripping members protruding from the body. When the fastener is inserted in a borehole formed in a substrate and a fastening member is threaded onto the threaded portion and tightened, the sleeve progressively moves along the angled surface causing the fingers to move outwardly and at least one of the gripping members to engage an inner surface of the substrate forming the borehole to secure the fastener in the borehole.Type: GrantFiled: January 6, 2017Date of Patent: May 5, 2020Assignee: Illinois Tool Works Inc.Inventors: Stanley J.

Patent number: 10330137Abstract: A self-drilling, self-cleaning fastener for a panel includes a head having a top side and an underside. The head has a diameter. A shank depends from an underside of the head and has a diameter less than the diameter of the head. A knurled region is adjacent the shank. The knurled region has a diameter and a plurality of spiral formed knurls having a twist in a first direction. The knurls define a major circumference as measured around peaks of the knurls. A threaded region is adjacent the knurled region and has a diameter less than the diameter of the knurled region. The threaded region has a thread form having a twist in a second direction opposite the first direction. A driving point is at an end opposite the head.Type: GrantFiled: March 29, 2017Date of Patent: June 25, 2019Assignee: ILLINOIS TOOL WORKS INC.Inventors: Yongping Gong, Daniel A. Sherrer
