PennEngineering microPEM TackPin fasteners

The microPEM TackPin fasteners are designed for compact sheet-to-sheet attachments, replacing screw installation in applications where disassembly is not required. The product is said to contribute to faster production times by eliminating tapping operations, the potential for stripped hardware or the need for patches, and all screw-related concerns.

The fasteners are pressed into properly sized mounting holes in the sheet to be attached and the base panel. The fastener clinches into the base panel and the fastener’s head subsequently holds the top sheet (as thin as 0.2 mm) firmly and permanently in place. The fastener’s tapered tip assists in location - interference fit eliminates hole-tolerance issues - and the self-clinching action results in full 360° metal contact. Loosening due to vibration or other factors is not a concern.

Benefits include: no cross-threading; assembly design for lighter, smaller and thinner products; full metal contact for grounding/conductivity; elimination of torque settings required for a screw; no excess cost due to screw breakage/overinstallation.
