PEM Self-clinching Fasteners

There are many reasons 90% of automakers choose PEM Self-clinching Fasteners on their vehicles. When using them, you will comply with industry standards, achieve reduced lead times, and better performance. Let’s look at additional benefits PEM Self-clinching Fasteners deliver to provide a competitive edge:

One Single Part Number, Anywhere in the World

With a single part number for each standard part, PEM Self-clinching fasteners make it easier to order and increase availability.

PPAP Available Parts

The extensive portfolio of standard parts is PPAP ready, as well as custom items.

Choose Your Technical Cleanliness Level

With the PEM® Clean Lab, you can achieve C400 and C600 technical cleanliness in accordance with project specifications.

Total System Solution with Haeger® Installation Machines

Get even greater efficiency and reliability while creating a total system solution when using PEM® fasteners with Haeger® installation machines.

SI Threaded Inserts and Compression Limiters

Automakers are using plastic in place of metal much more frequently. This has created a need for re-usable inserts that are both strong and water-resistant. The SI Threaded Inserts hold up even when frequent assembly and disassembly are required. SI® Compression Limiters are non-threaded inserts used in applications where the compressive load is applied to a plastic assembly. This strengthens the plastic to hold up under the compressive force applied during assembly.

PennEngineering Says of Their SI Compression Limiters:

  • Plastic integrity uncompromised by the applied load
  • Custom-engineered for many sizes and profiles
  • Flexible materials – brass, stainless steel, lead-free aluminum
  • Press-in, mold-in, heat staking, ultrasonic installation
  • Design types – flange head, symmetrical, full diamond knurl, non-knurled symmetrical
