Locknut 1/2"-13 18-8 Stainless Steel Waxed

18-8 stainless steel nylon insert lock nut  1/2" diameter, 13 threads per inch.  Stainless steel hardware is stronger and much more corrosion resistant over zinc plated or galvanized hardware.  These locknuts come pre "waxed", which is a lubricant applied to the locknut to prevent galling.
