UNI<\/strong> DIN<\/strong> DIN<\/strong> ANSI<\/strong> ISO<\/strong> Drawn screws are designed according to the customer\u2019s specific requirements and drawings, tailored to meet particular mechanical and functional needs. Each screw can be manufactured with customised geometries and specific surface treatments to enhance strength and durability.<\/p>\n<\/div><\/div><\/div> This screw is designed to provide a secure grip and optimum torque. Available in various lengths and threads, it is widely used in mechanical and structural applications.<\/p>\n<\/div><\/div><\/div> Hollow head screws are designed for applications requiring reliable fastening in tight spaces. The socket for Allen or Torx wrenches enables precise and secure tightening.<\/p>\n<\/div><\/div><\/div> Torx screws are designed to ensure high torque transmission and reduce the risk of damage to the drive. They are ideal for industrial applications that require precise, repeatable, and reliable fastening.<\/p>\n<\/div><\/div><\/div> Flanged screws feature an underhead flange that distributes the clamping load over a larger surface area. They are particularly suitable for applications subject to vibration and high mechanical stress.<\/p>\n<\/div><\/div><\/div> Primarily used in rail and profile assembly systems, hammer screws allow quick and reliable fastening without the need for extra drilling. They are also well suited to industrial applications<\/p>\n<\/div><\/div><\/div> Hexagon socket screws, also known as star screws, are designed for high-performance applications that require high torque. The 12-point drive facilitates installation and ensures optimal force transmission.<\/p>\n<\/div><\/div><\/div> Grub screws are headless screws used to secure mechanical components without protruding from the surface. They can have tapered, flat or cylindrical tips depending on the fastening requirements.<\/p>\n<\/div><\/div><\/div> This type of screw features two sections with different diameters, which are ideal for ensuring optimal fastening in components with holes of different sizes.<\/p>\n<\/div><\/div><\/div><\/div><\/div> We supply custom-designed fasteners for critical applications \u2014 with certified quality, full traceability, and technical support.
