Alternate Solutions

PennEngineering® recommendations for alternate hardware and cost savings

opportunities.

Alternate Solutions- I

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.

• Pan head

• DELTA PT16 x 4.5 mm overall

length

• Nickel plating

Alternate Solutions - II

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

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.

Alternate Solutions - V

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

Samsung Gear VR

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.
