The Black Grade 2 Hex Nut UNC is an industrial nut for machinery, metalworking fabrication, repairs, and assembly of parts with imperial thread. It is made of black carbon steel and works with UNC thread; when applicable, the reference relates to SAE J995 Grade 2. Its main difference is black finish and UNC coarse thread for non-exposed assemblies where compatibility with inch bolts is the priority. To purchase 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 by unit and organizes selection by actual catalog sizes for maintenance, replacement, and production purchases.

Both are Grade 2 UNC; the black nut is used in indoor or protected environments, while the zinc plated version adds light surface protection against corrosion.
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 and 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 by unit. For maintenance or production consumption, TECTUL can quote quantities by size.
