microPEM® Fasteners Overview

Types TA™/T4™ microPEM® TackPin® Fasteners

Two microPEM TackPin fasteners (types TA/T4) on white background

microPEM® TackPin® fasteners enable sheet-to-sheet attachment, replacing costly assembly with screws for applications where disassembly is not required.

Features:

  • Simple, press-in installation for secure attachment
  • Proven self-clinching technology resists vibrational loosening
  • Replaces micro screws, thus eliminating installation issues including cost of locking patch, cost of threaded insert or tapped hole, cost of driver bits and cost of rework due to cross-threading and driver bit cam-out
  • Top sheet can be any material
  • Automatic installation possible
  • Can be unscrewed if removal is necessary and reinstalled once, using a thread-locking adhesive

Type MPP™ microPEM® Pins

Two type MPP™ microPEM® Pins ideal for compact electronic assemblies on white background

Type MPP self-clinching microPEM® pins are ideal for compact electronic assemblies. These micro pins clinch permanently into place by simply pressing them into a mounting hole of the appropriate size. They can be installed into a variety of sheet materials up to a hardness of HRB 92/HB 195 and offer excellent corrosion resistance.

Features:

  • Suitable for demanding micro-positioning and alignment applications
  • Head closes flush, even in panels as thin as 0.5mm
  • The chamfered end facilitates mounting hole alignment
  • Can be installed into stainless steel sheets
  • Automatic installation possible
  • Excellent corrosion resistance

Type MSO4™ microPEM® Self-Clinching Standoffs

Two type MSO4™ microPEM® self-clinching standoffs for mounting or spacing in applications with limited space, shown on white background

These micro standoffs are designed for mounting and/or spacing in applications where space is extremely limited.

Features:

  • Can be installed into stainless steel sheets
  • Automatic installation possible
  • Much stronger threads than weld standoffs, because they are made from heat-treated 400 Series Stainless Steel

Types TKA™/TK4™ microPEM® TackSert® Pins

Two type TKA™ TK4™ microPEM® TackSert® Pins, designed for fastening a top panel to a bottom panel or chassis, on white background

microPEM® TackSert® Pins are designed to fasten a top panel to a bottom panel or chassis. The diagonal knurling of the parts interlocks with the lower panel or substructure and thus provides the required strength. Type TKA™ pins are suitable for plastic applications, whereas Type TK4™ pins are ideal for castings and brittle materials.

Features:

  • Securely fasten panels to common cast materials such as magnesium and aluminum as well as plastics such as ABS and printed circuit boards
  • Simple press-in installation – no heat or ultrasound required
  • Alternative to micro screws, eliminating the need for tapping or using threaded inserts
  • Top sheet can be any material
  • Low profile head
  • Eliminates costs for screws, patches to prevent loosening, threaded inserts or tapped holes, driver bits and rework due to cross-threading or driver bit cam-out
  • Automatic installation possible

Type SMTSO™ microPEM® Surface Mount Fasteners

Two SMTSO™ microPEM® Surface Mount Fasteners intended for PCBs on white background

These fasteners for compact electronic assemblies can be attached to printed circuit boards as nuts / standoffs.

Features:

  • Hex shaped barrel ensures optimal size/performance
  • Provided on tape and reel
  • Reduces panel handling
  • Automatic installation possible

Type TS4™ microPEM® TackScrew™ Fasteners

Three TS4™ microPEM® TackScrew™ fasteners for sheet-to-sheet fastening on white background

microPEM® TackScrew™ fasteners enable cost-effective sheet-to-sheet fastening by simply pressing them into place. They can be removed by simply unscrewing them, similar to other threaded fasteners.

Features:

  • Simple, press-in installation for secure attachment
  • Proven self-clinching technology resists vibrational loosening
  • Replaces micro screws, thus eliminating installation issues including cost of locking patch, cost of threaded insert or tapped hole, cost of driver bits and cost of rework due to cross-threading and driver bit cam-out
  • Top sheet can be any material
  • Automatic installation possible
  • Can be unscrewed if removal is necessary and reinstalled once, using a thread-locking adhesive
