The bichromate UNF hex flange nut in carbon steel is a fastener for assemblies where load distribution without a separate washer is desired, especially in mechanical assemblies with fine inch thread. At TECTUL it is specified by material, thread system and actual available size, because in industrial nuts compatibility depends on diameter as well as pitch and bearing type. For this product, the reference works with UNF thread and flange nut geometry covered by ASME B18.2.2 criteria for the inch series. It differs from the UNC flange nut by the fine pitch and from a standard hex nut by its enlarged bearing base. It is a useful option for maintenance, manufacturing and replacement purchases when the correct part must be identified without mixing similar catalog families.
