The Grade 8 UNC Hex Nut is an industrial nut for heavy machinery, production equipment, industrial maintenance and high-demand installations. It is made from grade 8 carbon steel and works with UNC thread; where applicable, the reference is related to SAE J995 grade 8. Its main difference is grade 8 for higher-load joints with compatible SAE fasteners. 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.

To quote the grade 8 unc hex nut, send the exact size, quantity and whether you need equivalence with a bolt, stud or threaded rod. We dispatch to Bogotá, Medellín, Cali, Barranquilla and all of Colombia. Request a quote via WhatsApp with TECTUL to confirm availability, finish and delivery times.
The price depends on size, finish and quantity. TECTUL quotes this reference per unit and can validate availability before dispatch.
Grade 8 is reserved for grade 8 bolts or equivalent design; it should not be mixed without validating the complete assembly.
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.
