PEM® microPEM® fasteners

The world has changed dramatically since screws were invented more than 2000 years ago. Empires have come and gone. Mankind went to the moon. Philly cheesesteaks were invented.

Yet, open up any cutting-edge electronic device, from laptops to cell phones to credit card readers, and what are you likely to see? Screws.

There’s a better way: TackPin® and TackSert® fasteners from microPEM®, a division of PEM and PennEngineering.

TackPin® and TackSert® fasteners are smaller than screws. They’re also lighter, stronger, more reliable, and simpler to install, which means faster production, less scrap waste and reduced maintenance needs on the line. They even cost less.

When it’s time to stop screwing around, #TackThat with TackPin® and TackSert® from microPEM®.

"We use a thread forming screw in our current generation of cameras. The head diameter is 4mm by 1.5mm and screw length is 6mm. The size of the TackSert® fastener was critical due to the reduction of our new camera size, clamp force requirements, cleanliness (thread forming screw required lubricant coating), and cycle time."
