PennEngineering’s PEM TSO4 self-clinching standoff fasteners allow secure component stacking

PEM® TSO4™self-clinching threaded standoffs from PennEngineering® can be used for secure stacking or spacing of components in ultrathin stainless steel assemblies. These hardened stainless steel fasteners clinch into stainless sheets as thin as 0.025 in. and become permanent parts of an assembly.

The fastener’s thread design at the barrel end minimizes the length for a mating screw. Shorter standoffs typically are through-threaded, and longer standoffs are blind. Thread-type variations with a thicker wall can further be specified to provide increased bearing surface for the mating component or panel. For applications in potentially corrosive environments, an optional nickel plating can be added for corrosion resistance.
