PEM Type T4™ Self-clinching microPEM® TackPin® for Installing Into Stainless Steel On PennEngineering

New self-clinching microPEM® TackPin® (Type T4™)fasteners are ideal for installation into stainless steel and higher strength aluminum alloy sheets. They are for use in compact electronic assemblies enabling sheet-to-sheet attachment, replacing costly screw installation in applications where disassembly is not required. TackPin&reg fasteners eliminate typical screw-related issues (including tapping, cross-threading, torque control, and vibration backout) and ultimately promotes quick and easy installation with minimal hardware. TackPin&reg fasteners can provide a good alternative to welds or adhesives.
