Composite Fastener with Locking Cap Feature
United States Patent 11,209,041
Issued December 28, 2021
Inventors: Donald Wayne Rice, Ripley, NY, USA
Assignee: Sky Climber Fasteners LLC, Delaware, OH, USA
A fastener comprising a nut body and an associated Lockone clasp is disclosed. The locking clasp may be maintained in its association by one or more locking clasp retainers, the retainers forming an arc.

Self-Clinching Fastener
United States Patent 11,209,040
Issued December 28, 2021
Inventors: Marc Andrew O’Donnell, Burlington, CA, USA
Assignee: RB&W Manufacturing LLC, Streetsboro, OH, USA
A self-clinching fastener for attachment to a plastically deformable metal panel includes a body portion with a central axis, the body portion has an outer peripheral surface extending in a direction perpendicular to the central axis. A punch portion is coaxial with the central axis and extends from the body portion such that the annular-shaped surface encircles the punch portion, the punch portion includes an outer peripheral surface extending in the direction of the central axis. A plurality of spaced apart lugs encircle the punch portion and axially projecting outwards from the annular-shaped surface, one of the lugs has a contact face configured to engage the metal substrate, the contact face declining, relative to an imaginary horizontal plane on which the annular-shaped surface lies, in a radially outwards direction of the self-clinching fastener.
