System and Method for Sealing a Metal Fastener from Electrolyte in an Area of Dissimilar Metals
United States Patent 11,339,823
Issued May 24, 2022
Inventor: David Demaratos, Wixom, MI, USA
Assignee: J.S.T. Corporation, Farmington Hills, MI, USA
A sealing system and a method for sealing a metal fastener and members having dissimilar metals for a header connector or a connector device from electrolyte in an area where, in the header connector or the connector device, certain dissimilar metals may be in contact. The metal fastener and other adjoining or abutting dissimilar metals are sealed by a non-conductive seal from electrolyte, thereby protecting the metal fastener and the other adjoining or abutting dissimilar metals from galvanic corrosion and subsequently protecting the integrity of the header connector or the connector device.

A bolt of the present invention is a high-strength bolt of high-carbon steel having a tempered martensite structure, wherein the composition of the bolt comprises: 0.50 mass % or more and 0.65 mass % or less of carbon (C); 1.5 mass % or more and 2.5 mass % or less of silicon (Si); 1.0 mass % or more and 2.0 mass % or less of chromium (Cr); 0.2 mass % or more and 1.0 mass % or less of manganese (Mn); and 1.5 mass % or more and 5.0 mass % or less of molybdenum (Mo); a total content of impurities being phosphor (P) and sulfur (S) is 0.03 mass % or more; and the remaining is iron (Fe). Furthermore, the carbon concentration satisfies the following Formula (1): 0.75≤X<1 . . . Formula (1) wherein, in Formula (1), X represents surface carbon concentration/inner carbon concentration. Therefore, the bolt of the present invention has low quench cracking susceptibility and excellent delayed fracture resistance, because an increase in temperature at which martensite transformation occurs (Ms point) on the surface side is held down.

The axial recess defining an axial depth (LB). The ratio of recess axial depth (LB) to shank diameter (DS) is less than 0.3. And in a deformed state, after the creation of the riveted joint, the rivet extends through the first workpiece and penetrates the second workpiece; and the head bears against the upper surface.

Threaded Fastener with a Hybrid Self-Drilling Tip
United States Patent 11,326,638
Issued May 10, 2022
Inventor: Michael C. Dill, Elk Grove Village, IL, USA
Assignee: Illinois Tool Works Inc., Glenview, IL, USA
The present disclosure provides a threaded fastener having a hybrid self-drilling tip or drill tip. The fastener includes a head, a shank connected to and extending from the head, a helical thread formation extending radially outwardly from part of the shank, and a self-drilling tip including a first tapered tip portion and a second tapered tip portion. The first tapered tip portion is connected at a first end to the shank and at a second end to the second tapered tip portion, and the second tapered tip portion terminates in a pointed end. The outer diameters of both tapered portions taper radially inwardly moving in the direction of the pointed end, which renders the fastener suitable for attachment to wood as well as for fastening two metal objects to one another.

Assignee: Semblex Corporation, Elmhurst, IL, USA
A fastener has a generally cylindrical shank and a driver at a first end of the shank. The shank has a thread having a first side and a second side opposed to the first side. The first and second sides form a compound angle between the shank and an apex where the first and second sides meet. The compound angle is formed by a body portion extending along the first and second sides from the shank to an intersection, and a crest portion extending along the first and second sides from the intersection to the apex. The first and second sides in the body portion form a body angle with respect to each other, and the first and second sides in the crest portion form a crest angle with respect to each other. The crest angle is greater than the body angle.
