Hex Nuts

Need a hex nut that holds torque and stays put? We stock everything from Grade 2 and Grade 5 for everyday repairs to Grade 8, 2H and L9 for high-clamp joints. Go coarse for fast run-down, fine for tighter adjustment. Choose stainless, brass, bronze or Armor Coat for wet, salty or chemical areas. Add jam or heavy hex when space or wrenching is tight.
