Grade 2 UNC-UNC black oxide stud made of carbon steel, used in general fastening, light machinery, supports and non-critical assemblies. TECTUL presents it with actual lot sizes and the attribute that avoids confusion: this version has UNC thread on both ends; it is not mixed UNC-UNF. The purchase specification must confirm diameter, effective length, thread pitch, finish and compatible nut, because in industrial fasteners a pitch mismatch can prevent assembly or reduce actual tightening load. For inch studs and rods, the UNC or UNF thread families of ASME B1.1 are used as a reference; for metric thread, verify M diameter, pitch and the class indicated on the drawing or sample. If the product works in a flange, support, equipment or spare part, select by service condition and not only by visual similarity. This sheet prioritizes fast identification, thread compatibility and technical quotation for industrial buyers in Colombia.

We dispatch to Bogotá, Medellín, Cali, Barranquilla and all of Colombia. Request a quote via WhatsApp at TECTUL indicating size, quantity, finish and whether you need a certificate, compatible nut or cut-to-size service for grade 2 UNC-UNC black oxide stud.
The price depends on size, quantity, finish and availability. Send us reference 1/2 X 5 or the required size via WhatsApp for a quote.
the UNC-UNF stud combines coarse and fine pitch; this UNC-UNC version keeps the same pitch on both ends
It must be installed with a clean thread, compatible nut and the tightening method defined by the joint design. Do not mix UNC, UNF or metric threads unless the drawing authorizes it.
The lot includes sizes such as 1/2 X 5 through 3/4 X 4. The table in the sheet shows the actual sizes loaded for quotation.
Indicate diameter, length, thread pitch, finish, quantity, delivery city and whether you require a nut, washer, certificate or cut-to-size service.
It depends on the finish and the environment. For exposure, zinc plating, hot-dip galvanizing or stainless steel is evaluated; for critical services, engineering specification should be verified.
