The Bichromate UNC Flange Nut is an industrial nut for machinery, sheet metal, supports, guards and quick assemblies with inch thread. It is made from bichromate carbon steel and works with UNC thread; where applicable, the reference is related to UNC thread. Its main difference is an integrated flange that distributes bearing and reduces the need for a flat washer in many assemblies. To buy without errors, the critical data is not only the diameter: the pitch, thread series and grade or material of the bolt, stud or threaded rod must also match. TECTUL offers it per unit and organizes selection by actual catalog sizes for maintenance, replacement and production purchases.

The price depends on size, finish and quantity. TECTUL quotes this reference per unit and can validate availability before dispatch.
The flange nut has an integrated flange for bearing; the standard hex nut is usually combined with a washer if the assembly requires it.
Clean the thread, confirm diameter and pitch, start threading by hand and tighten with the proper tool according to the torque defined for the assembly.
Take the nominal diameter and pitch of the male thread. In inch threads, distinguish UNC from UNF; in metric, confirm the pitch indicated in millimeters.
It depends on the material and coating. Stainless steel and hot-dip galvanized finishes better resist exposure; zinc plated, black or black oxide finishes are recommended for protected environments.
The lot is configured per unit. For maintenance or production consumption, TECTUL can quote quantities by size.
