PRODUCTS<\/a> | SCREWS<\/a><\/p>\n<\/div> Industrial flanged screws are fastening components designed to distribute the tightening load over a larger surface area than traditional hex head screws. The integrated flange helps reduce surface pressure, improve joint stability and, in many cases, eliminate the need for separate washers.<\/p>\n Thanks to these characteristics, flanged screws are used in applications subject to vibration, dynamic loads and continuous duty cycles. They are particularly widespread in the heavy-duty automotive, agricultural machinery, earthmoving, machinery, power transmission and industrial plant engineering sectors.<\/p>\n In addition to standard versions, the industrial market increasingly requires special made-to-drawing flanged screws with dedicated geometries, fine threads, specific surface treatments and integrated locking systems.<\/p>\n EFS supports standard and special supplies with certified European materials, controlled treatments and customized production for critical industrial applications.<\/p>\n<\/div><\/div><\/div> The main characteristic of flanged screws is the presence of an integrated flange under the head, which increases the bearing surface and improves preload distribution.<\/p>\n This configuration makes it possible to:<\/p>\n In applications subject to continuous vibration, the flange also helps maintain a more stable connection over time.<\/p>\n<\/div> Hexagon flange head screws are the most widely used configuration in the industrial sector.<\/p>\n The hexagon head allows high torque values to be applied, while the integrated flange improves stress distribution on the assembled component.<\/p>\n These screws are used in structural frames, engine mounts, gearboxes, agricultural machinery, transmissions and mechanical systems subject to high loads.<\/p>\n<\/div> Some configurations feature radial serrations under the flange, increasing friction with the bearing surface.<\/p>\n This solution, also known as a serrated flanged screw, is used when loosening caused by vibration or cyclic loads must be counteracted without using additional locking systems.<\/p>\n Serrated versions are particularly common in the automotive sector and in earthmoving machinery.<\/p>\n<\/div> Flanged screws with fine metric thread are used when more precise preload adjustment or greater resistance to loosening is required.<\/p>\n Fine thread increases the contact surface between the threads and helps improve tightening stability in applications subject to strong vibration.<\/p>\n<\/div> Many industrial applications require configurations that fall outside the dimensions covered by standard regulations.<\/p>\n The most commonly requested customizations include:<\/p>\n We supply custom-designed fasteners for critical applications \u2014 with certified quality, full traceability, and technical support. Industrial flanged screws are used in many sectors characterized by high mechanical stress.<\/p>\n In the heavy-duty automotive sector, they are used in gearboxes, differentials, engine mounts, axles and transmission systems.<\/p>\n In agricultural and earthmoving machinery, they are used in frames, structural assemblies, transmission components and parts subject to continuous vibration.<\/p>\n In the machinery sector, they are used in gearboxes, mechanical assemblies, presses and automated lines.<\/p>\n Flanged screws are also used in industrial plant engineering, energy systems, material processing machines and equipment subject to frequent load cycles.<\/p>\n<\/div><\/div><\/div> The main reference standards for industrial flanged screws include:<\/p>\n The choice of standard depends on the required geometry, property class and technical specifications of the application.<\/p>\n<\/div><\/div><\/div> The most common configurations include:<\/p>\n Flanged screws can be manufactured in different materials depending on the operating conditions and project requirements.<\/p>\n The most commonly used materials include:<\/p>\n Material selection must take into account mechanical strength, operating temperature, corrosive environment and the required durability of the connection.<\/p>\n<\/div><\/div><\/div> Surface treatments make it possible to increase corrosion resistance and improve fastening performance.<\/p>\n The main treatments available include:<\/p>\n For high-strength flanged screws, non-electrolytic coatings such as Geomet\u00ae are particularly suitable because they reduce the risk of hydrogen embrittlement.<\/p>\n<\/div><\/div><\/div> EFS manages standard and special supplies of flanged screws for industrial applications subject to high static and dynamic loads.<\/p>\n The main activities include:<\/p>\n Thanks to a network of qualified European manufacturers, EFS supports supplies for the heavy-duty automotive, agricultural machinery, earthmoving, machinery, energy and industrial plant engineering sectors.<\/p>\n<\/div><\/div><\/div> The integrated flange increases the bearing surface and distributes the tightening load more effectively. In many applications, it also makes it possible to eliminate the washer and improve joint stability.<\/p>\n<\/div> Serrated versions are used when it is necessary to increase resistance to loosening caused by vibration and dynamic loads.<\/p>\n<\/div> The most common property classes are 8.8, 10.9 and 12.9 according to ISO 898-1. The choice depends on the applied loads and the characteristics of the assembly.<\/p>\n<\/div> Yes. Flanged screws can be manufactured with custom geometries, fine threads, special diameters, dedicated treatments and integrated locking systems according to the project 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.Industrial Flanged Screws<\/h1><\/div><\/div><\/div>
