ASTM A193 B7 40 inch rod made of heat-treated alloy steel, used in fabrication of studs for flanges, plant maintenance and process assemblies. TECTUL presents it with actual lot sizes and the attribute that avoids confusion: it is sold as a 40 inch B7 rod; it is not a B7 stud already defined by assembly length. 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.

the B7 stud sold by unit comes in a specific length; this rod is purchased for later cutting or machining
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 40" x 1" through 40" x 9/16". 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.
