• Hex Flange Nuts
  • As part of our high-quality line of flange nut fasteners, National Bolt & Nut offers a variety of hex flange nuts that meet IFI-145 dimensions. Our hex flange nuts are equipped with a wider flange that distributes pressure equally over the components being fastened, assuring a more secure hold.
  • Our hex flange nuts are equipped with either course or fine threads. Nylon inserts and nuts with patches are also available, which help prevent our hex flange nuts from loosening during vibration.
  • Other materials and finishes available. For further information, call or send an information request.
