Multi-Clinch Fastener Insert
US 11549531 January 10, 2023
Inventor: Jonathan Brunk, Philadelphia, PA, USA
Assignee: Penn Engineering & Manufacturing Corp., Danboro, PA, USA
An insert for the attachment of objects to composite or plastic panels consists of two parts, a retainer
and an insert. The retainer has a through-hole and knurls on its perimeter for gripping the walls of a
receiving hole in the composite or plastic panel. The insert has multiple self-clinching features at
increasing diameters, which when inserted into the retainer rigidly attach it to the retainer. The panel is
rigidly clamped between opposite sides of the panel by an enlarged head of the retainer and an opposing
flange on the insert. The selfclinching features of different diameter permit the device to be used with
panels of different thickness and allow a large tolerance range. A plain or threaded stud can be
substituted for the threaded hole of the insert. Both the retainer and the insert can be metallic.

Pressure Lock Retention Fastener
US Patent 11549538
Issue January 10, 2023
Stephen M. Hill, Buckley, WA, USA
In implementations of a pressure lock retention fastener, the fastener assembly includes an insert sized
for insertion into a fastener hole in a first panel. The fastener assembly has a threaded collet sized to
slide in the insert and has expandable flanges that extend below the insert. The expandable flanges are
sized for insertion into an aligned hole in a second panel. The fastener assembly also includes a screw
installable through the insert to engage the threaded collet. The screw exerts a force that pushes the
expandable flanges outward as screw rotation drives the screw into the threaded collet, and ridge locks
of the expandable flanges seat up against the second panel effective to fasten the panels together. In
implementations, a plate is installable between the panels with slotted holes having antirotation tabs that
prevent a fastener assembly from spinning in the panel holes.
