New PEM® self-clinching stainless steel standoff fasteners with bright nickel plating provide ideal corrosion resistance and contribute to an attractive finish in stainless steel assemblies. These 400 Series stainless steel threaded fasteners from PennEngineering® allow for the mounting, spacing, or stacking of panels, boards, or components and will install reliably into thin stainless host sheets by pressing them into pre-punched and properly sized round mounting holes. After installation into sheets with hardness up to HRB 88 / HB 183, they become permanent parts of an assembly and will not loosen or fall out. A mating screw completes the attachment process.
This nickel-plated stainless product line includes Type SO4™ through-hole threaded standoffs, Type BSO4™ blind threaded standoffs (whose closed threads enable a flush appearance on the back side of the host sheet), and Type TSO4™ threaded standoffs uniquely engineered for installation into especially thin stainless sheets.
Type SO4 and Type BSO4 standoffs are available in thread sizes from #4-40 through #8-32 / M3 through M5 and will install in stainless sheets as thin as .040” / 1mm. Type TSO4 standoffs are offered in thread sizes from #2-56 through #6-32 / M2.5 through M3.5 and will install in stainless sheets as thin as .025” / 0.63mm.
