KD Fasteners, Inc. can supply you with all of your heavy hex nut needs.

Heavy hex nuts are slightly wider and thicker than the standard hex nut and they pair with large diameter, high strength, heavy hex bolts. Heavy hex nuts advantages include a greater length of thread engagement and better resistance to stretching or widening.

Heavy hex nut coatings include zinc, zinc yellow and hot dipped galvanized. We offer heavy hex nuts in standard (inch) and metric sizes ranging from ¼ to 4 inches.

Heavy hex nuts are available in a wide variety of metals. These include:

  • Stainless steel
    • 300 series stainless steel
    • 316 series stainless steel
  • Inconel
  • Titanium
  • Aluminum
