Product Description

The M8x25 hex socket screw, also known as a Cylindrical head DIN 912 compliant fastener or M8x25 socket cap screw, features a cylindrical head with internal hex drive (ISO 4762 standard). This metric screw has an 8mm diameter and 25mm length, designed for precision assembly in machinery, automotive, and electronics. The cylindrical low-profile head enables space-constrained installations with 6mm hex key operation. Typical torque ratings range 20-25Nm for steel versions. Available in stainless steel (A2/A4) or carbon steel with zinc/black oxide coatings, it offers corrosion resistance in operating temperatures from -50°C to +250°C. Key advantages include high tensile strength (up to 12.9 grade), vibration resistance, and flush mounting capability. Limitations include potential stripping of socket drive under excessive torque. Ideal for secure fastening in structural frames, motor assemblies, and industrial equipment enclosures.
