Who is PennEngineering?
• Penn Engineering & Manufacturing Corp. (PEM)
founded in 1942 in Doylestown, Pennsylvania, USA is
the global leader in the design and manufacture of thin
sheet fastening devices and installation systems.
• PEM is the inventor and continues to be the sole
manufacturer of genuine PEM® brand fasteners.
• We currently have regional manufacturing and
technical centers in two U.S. locations, Ireland and
China.

PENNENGINEERING Technical Services
• On-Site training.
• Comprehensive website includes complete
fastener 3D modeling capabilities.
• Trained field technical representatives
• Global testing laboratories.
• Cost Savings Investigations (C.S.I.).
• Prototype development.
• Installation solutions.
8
What is the “micro” in microPEM?
•
•
•
•
•

Threads as small as M1.
Pin diameters as small as 1mm.
Standoff lengths as short as .040”/1mm.
Attach sheets as thin as .003”/0.08mm.
Clinching into sheets as thin as .012”/0.3mm.

Smaller products are in development.
9
Why so small?
We actively conduct Product Teardowns and CSI
reviews for our customers. We have found in our analysis and
investigations that they often need smaller and smaller clinch
fasteners for thinner and thinner panels, to replace the
adhesives, rivets or welds they have been using. This is driving
us to provide more assembly options for when they are
designing their next product.

Micro Fasteners Overview

A new family of solutions from PennEngineering

MPP

MPP - Micro Pin
• Satisfies micro positioning and
alignment requirements with pin
diameters as small as 1.0mm.
• Flush installation into materials as thin
as .020” / 0.5mm and as hard as HRB
92 / HB 195, such as stainless steel.
• Made from A286 - excellent corrosion
resistance.
• Chamfered end eases mating hole
alignment.
• RoHS compliant.

MPP – Application Example

Phone: Pin used as a spring anchor.
13
MPP – Application Example

400,000 per day, replacing weld pins
14
MSO4

MSO4™ - Self-clinching Micro Standoffs
• Thread sizes: M1.0, M1.2, M1.4, M1.6,
#0-80, #2-56
• Made from 400 Series Stainless Steel
• Installs into materials with a maximum
hardness of HRb 88 and as thin as
0.4mm / .016”
(0.3mm / .012” possible with
modification)
• Lengths as short as 1mm or .04”
• Round, knurled head for close
centerline to edge placement.
• RoHS compliant
15
MSO4 – Application Example

Phone: Standoffs clinched into 0.4mm/.016” stainless.
16
MSO4 – Application Example

Cell phone: M1.4 Standoff clinched into 0.43mm/.017” stainless.
17
MSO4 – Application Example

Cell phone: M1.4 Standoff welded onto 0.4mm/.016” stainless.
18
MSO4 – Application Example

Laptop: M2 standoffs clinched into 0.5mm/.020” stainless
heatsink mounting plate.
19
MSOFA – Flaring Standoff – Application Example

Camera: M1.6 standoffs flared into 0.2mm/.008” stainless
heatsink mounting plate.
20
SMTSO

Micro SMTSO
• Surface mounted to PCB.
• Thread sizes down to M1.
• Material choices: Brass,
Steel
• Bright or Matte Tin plated
• Sold Loose or Tape-And-Reel
• Hex body for additional
strength.
21
SMTSO – Application Example

Laptop: M2 SMT nuts 1mm tall on PCB
2.5mm ID spacer
22
Inserts for Plastic

SI® Brand Micro Inserts for Plastics
• Thread Sizes from M1.0
• Material choices: Brass,
Stainless Steel
• Style Choices: Ultrasonic,
Heat-Stake, Molded-In,
Press-In

23
Do you use micro screws?
1.

Yes – only to hold an assembly together.

2.

Yes – to allow for disassembly and reassembly.
There are now two new engineered solutions.

24
Micro TackPin

Yes – to hold an assembly together.
Solution = Micro TackPin

25
Micro TackPin

• Intended for attaching two surfaces together, much the way a screw
would. The part clinches into the bottom member while retaining the
top member with a head.
• Tapered tip assists in assembly into the very small mounting hole.
• Interference band sizes hole during assembly to alleviate tolerance
concerns.

26
Micro TackPin

27
Micro TackPin

Value = Significant Cost Reduction

28
Micro TackPin – Application Example

Over 250 million screw replacements this year for this project
Over 150 million more for two other projects
29
Micro TackPin – Application Example

PCB to copper busbar
30
Micro TackPin

• What is the benefit to use a PEM® TackPin instead of a screw?
o The PEM® TackPin is stronger in pullout than the thread strength of a
screw of the same length.
o No risk of cross-threading.
o Less weight than a screw.
o Smaller than a screw, so designs can be thinner/smaller.
o No need for the cost of a nylon locking patch.

31
Micro TackPin

• What is the process cost savings?
Simplified assembly - press-in versus turned screw.
Throughput is faster.
No need to control torque settings to drive screws.
No scrap costs due to cross-threading, over installation, or screw
breakage during assembly.
o If adhesives are used, a PEM® TackPin can be used without any
recycling concerns that adhesives can cause.
