Countersunk Torx screw M3x10 T10 ISO 14581 4.8 Zn

Torx flat head screw. Material: bright zinc-plated steel (Zn 4.8 and 8.8), stainless steel (A2 and A2-70), and acid-resistant steel (A4 and A4-70). Material hardness depends on screw size. Metric thread pitch. Torx drive (Tx). Screw type and design: flat head.

ISO 14581 is an international standard that specifies the characteristics of countersunk head screws with a TX drive (Torx). It is commonly used in industry and assembly applications where a clean appearance and efficient fastening are required. The countersunk head allows the screw head to sit flush with the material surface, enabling smooth, snag-free finishes. The TX drive (Torx) allows high torque transfer without the tool slipping or damaging the head. This improves installation productivity and reduces tool wear. Limited load capacity: the standard defines screws that, due to their head design, have limited load capacity (approximately 80% compared to the thread). Therefore, they are not suitable for the most critical strength requirements, for which a higher-head standard such as ISO 14582 is recommended. Used in applications such as machine building and electronics. Provides precise and neat fastening for components.
