HEX JAM NUTS 18-8 STAINLESS

A six-sided internally threaded 18-8 stainless steel fastener which is only two thirds the thickness of a full form nut. Jam nuts are tightened against the work surface and a finished or heavy nut is generally tightened against the jam nut to keep it from loosening.

Stainless steel provides corrosion resistance against atmospheric conditions, moisture, salt, and other extremes of weather. Often used in marine applications.
