Heavy Hex Nuts, or Structural Nuts, hold the world together — in charge of securing together buildings, bridges, and warehouses. Their job is to bolt I-beams to one another in order to raise structures. Heavy Hex Bolts provide a greater width across the flat compared to Finished Hex Bolts for a dispersed clamping load. Earnest offers Grades 5 and C, also available in lefty threads.
