Installs into stainless steel

(1) Standoffs with thru-hole codes 6116, 8143, 63.1 and 83.6 have a thicker wall to provide more bearing surface for the mating component or panel

reducing the chance of cracking or cutting into the board.

Please contact your local PEM® distributor for availability, minimum quantity, and pricing information.

* NC suffix is required if optional nickel plating (for corrosion resistance)

is desired. Otherwise, no suffix is necessary.
