Alternate Solutions- I
Section Heading Slide – Do Not Remove
PennEngineering can be able to provide all of the
DELTA PT16 x 4.5 mm pan head self-tapping
screws with different design solutions. PEM has
license with Torx®, Torx Plus®, and Phillips® Drive
System, RemForm ® thread profile and has
capability to do both Zinc and Nickel plating.

Alternate Solutions - II
Section Heading Slide – Do Not Remove
PennEngineering can be able to provide
different sizes and installation brass
inserts to meet the application
requirement. As a alternate solution,
TackSerts and Type MSIB microPEM
Insert shall be a good way to achieve
savings in operating cost and improve
efficiency in applications.

Alternate Solutions - III
Section Heading Slide – Do Not Remove
PennEngineering can provide
different sizes of metric micro screws to
meet the application requirement. PEM
has license with Torx®, Torx Plus®, and
Phillips® Drive System and has
capability to do both Zinc and Nickel
with different color. As an alternative
solution, PEM TackSert can be used to
replace the traditional micro screws for
achieving savings in operating cost and
improve efficiency in applications.

M1.6 threaded Insert could be
replaced by a new part depicted in the
print in the right. The design in the
right may be a good way to achieve
savings in operating cost and
improving efficiency in applications.

Conclusions and Summary
Throughout the entire teardown process, we discovered 24 pieces
DELTA PT16x4.5 mm pan head self-tapping screws, 10 pieces brass made
M1.4 threaded insert, 7 pieces metric profile thread screws and one brass
made M1.6 threaded insert in the device. All of these fasteners can be replaced
by PEM, same size micro fasteners.
As an alternate solution, PEM TackSert® fasteners can be used to
replace the traditional micro screws for achieving savings in operating cost and
improving efficiency in applications.
For the Alternate Solution – V, borrowing experience from the Core
Size TackSert design, manufacture, installation and testing the ideas illustrated
on the slide #32 may be a good way to achieve savings in operating cost and
improve efficiency in applications.
