The ASTM A563 Grade DH Black Nut is an industrial nut for steel structures, anchors, heavy assemblies and compatible ASTM bolts. It is made from black carbon steel and works with UNC thread; where applicable, the reference is related to ASTM A563 grade DH. Its main difference is grade DH without galvanizing for protected structural assemblies or with the finish defined by the project. 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 black nut is not hot-dip galvanized; the HDG version is used when the project requires coating for exposure.
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.
