Long zinc-plated coupling nut for UNC threaded rod made of zinc-plated carbon steel, used in splicing threaded rods, extending supports and assembly adjustments. TECTUL presents it with actual lot sizes and the attribute that avoids confusion: it is not threaded rod; it is the long connector for joining two compatible lengths. 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 long zinc-plated coupling nut for UNC threaded rod.
The price depends on size, quantity, finish and availability. Send us reference 1/2 or the required size via WhatsApp for a quote.
threaded rod provides the length; the long coupling nut is used to splice lengths with the same thread
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 through 5/8. 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.
