Standoff Fasteners Resist Corrosion


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 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.


Type SO4 and Type BSO4 standoffs come in:

  • thread sizes from #4-40 through #8-32/M3 through M5
  • will install in stainless sheets as thin as 0.040 in./1 mms
