with a small clearance. The connecting elements have guide surfaces which guide the nut parts in a
rotational movement about an axis of rotation extending transversely to the axis of the internal thread
when displaced into the use position. Each nut part has at least one first locking arm which has on one
side a guide surface which induces the rotational movement when the nut parts are displaced and
bears against a complementary guide surface on a second locking arm of the other nut part.

which the weldable material melts.

Clinch Fastener
US Patent 11614118
Published March 28, 2023
Inventors: Steven P. Donovan, Roscoe, IL, USA; and Bryan D. Warju, II, Lake Orion, MI, USA
Assignee: Acument Intellectual Properties, LLC, Sterling Heights, MI, USA
A clinch fastener that includes a plurality of ribs disposed under a head of the clinch fastener, wherein
the ribs are specifically configured to displace host material more evenly than conventional clinch
fasteners. To that end, in cross section, along a line, arc, or combination, going from a central axis of
the clinch fastener to an outer periphery of the head of the clinch fastener, each rib preferably
provides a curved surface that is formed of multiple sections, wherein different radii define at least
two of the sections. The configuration of the ribs allows for a vented escape of host material beyond
the rib outside diameter and provides for radially focused material displacement, thereby releasing
stress within the host material and reducing warping during clinching.
