PRODUCTS<\/a> | CUSTOM-MADE STUD BOLTS<\/a><\/p>\n<\/div> Industrial threaded rods are fastening components characterized by a continuous thread running along the entire length of the component. They are used in steel construction, plant engineering, support systems, industrial structures and Oil & Gas applications where adjustable connections or assemblies with lengths greater than those normally available in standard fasteners are required. <\/p>\n Unlike industrial stud bolts, which are generally identified as components intended for specific plant engineering or structural applications, threaded rods are often supplied in commercial lengths and can be cut or adapted directly during assembly.<\/p>\n In the European industrial market, DIN 975 and DIN 976 metric threaded rods are widely used, while in the Oil & Gas, energy and international plant engineering sectors, inch-size threaded rods manufactured according to ASTM specifications are in high demand.<\/p>\n<\/div><\/div><\/div> The main characteristic of threaded rods is the continuous thread running along the entire useful length of the component. This configuration allows great flexibility of use and makes it possible to adapt the fastener to assembly requirements directly in the workshop or on site. <\/p>\n Threaded rods are normally used with nuts and washers and can be supplied in different diameters, thread pitches and lengths.<\/p>\n The main configurations include:<\/p>\n For demanding industrial applications, high-strength materials, dedicated dimensional inspections, certifications and specific surface treatments may be required.<\/p>\n<\/div><\/div><\/div><\/div><\/div> We supply custom-designed fasteners for critical applications \u2014 with certified quality, full traceability, and technical support. Threaded rods are used in many industrial sectors thanks to their ease of installation and the possibility of easily adapting the length of the connection.<\/p>\n<\/div><\/div><\/div> They are used for bracing systems, adjustment systems, structural fastenings, steel construction connections and civil and industrial installations.<\/p>\n<\/div><\/div><\/div> Threaded rods are widely used for pipe supports, brackets, ducting, HVAC systems, cable trays and suspension systems.<\/p>\n<\/div><\/div><\/div> In energy and petrochemical plants, inch-size threaded rods manufactured in ASTM materials such as A193 B7, B16 and A320 L7 are frequently used. In these contexts, the availability of certifications, traceability and controlled mechanical properties is an essential requirement.<\/p>\n<\/div><\/div><\/div> Threaded rods are also used in industrial machinery, special equipment, production plants and structures subject to high loads, where a simple but reliable fastening solution is required.<\/p>\n<\/div><\/div><\/div> Metric threaded rods are commonly identified on the market by the DIN 975 reference, a designation still widely used by purchasing departments and in technical specifications. The current reference standard is DIN 976-1<\/strong>, which defines the dimensional characteristics of fully threaded rods. <\/p>\n Metric threads are generally manufactured according to:<\/p>\n In the Oil & Gas, energy and international plant engineering sectors, inch-size threaded rods with UNC and UNF threads are widely used, manufactured in ASTM materials such as:<\/p>\n These rods are frequently used in plants, valves and flanged connections designed according to sector-specific ASME\/ANSI standards. Used in steel construction, plant engineering and industrial construction where standard corrosion protection is required.<\/p>\n<\/div><\/div><\/div> Particularly used in humid environments, food industries, chemical plants and outdoor applications.<\/p>\n<\/div><\/div><\/div> Manufactured in certified materials for energy plants, petrochemical plants and applications characterized by high documentation and performance requirements.<\/p>\n<\/div><\/div><\/div> EFS manages supplies of threaded rods in:<\/p>\n Material selection depends on environmental conditions, the required mechanical strength and the possible presence of corrosive agents or high temperatures.<\/p>\n<\/div><\/div><\/div> Surface protection for threaded rods is defined according to the operating environment and the expected durability of the connection.<\/p>\n The most commonly requested treatments<\/a> include:<\/p>\n In structural and infrastructure applications, as well as in lifting systems, threaded rods with Geomet\u00ae 500B coating are frequently required thanks to its high corrosion resistance and absence of hydrogen embrittlement risk.<\/p>\n<\/div><\/div><\/div> EFS supports supplies of standard and special threaded rods through a network of qualified Italian and European manufacturers.<\/p>\n The company coordinates certified materials, surface treatments, machining operations and quality controls, also managing oversize diameters, non-standard lengths, special materials and supplies accompanied by EN 10204 3.1 and 3.2 certifications.<\/p>\n Supplies include both metric threaded rods for steel construction and plant engineering, and inch-size threaded rods for the Oil & Gas, energy and process plant engineering sectors.<\/p>\n<\/div><\/div><\/div> A threaded rod is generally a standard product supplied in commercial lengths. A stud bolt, on the other hand, is a component intended for a specific industrial application, often manufactured to size and accompanied by dedicated technical documentation.<\/p>\n<\/div> DIN 975 is the designation historically used to identify metric threaded rods. The current reference standard is DIN 976-1, which defines their dimensional characteristics.<\/p>\n<\/div> The most commonly requested materials are ASTM A193 B7, ASTM A193 B16 and ASTM A320 L7, selected according to the operating conditions, temperature and plant specifications.<\/p>\n<\/div><\/div><\/div><\/div><\/div> We supply custom-designed fasteners for critical applications \u2014 with certified quality, full traceability, and technical support.Threaded Rods<\/h1><\/div><\/div><\/div>
