Our long T-nuts in accordance with DIN 508 L are the ideal solution for secure, positive connections in T-slot systems. Manufactured from high-quality steel of strength class 10, these T-nuts offer increased tensile strength and are particularly suitable for applications with high mechanical loads. The extended design ensures a larger contact surface in the T-slot – this increases the holding force and minimises the risk of tilting torques during heavy clamping. <\/p>\n
