Product Description

The Cylindrical head M5-90 screws, also referred to as M5x90 hex socket screws, are metric hex socket cap screws designed for precision fastening in machinery, automotive, and industrial equipment applications. These screws feature a cylindrical head with an internal hexagonal drive (ISO 4762 standard), M5 thread diameter, and 90mm shaft length. Manufactured from high-grade steel (typically ISO 4.8 or 8.8 strength grades), they offer excellent resistance to vibration and corrosion, with common surface treatments including zinc plating or black oxide. Operating temperature ranges from -50°C to 120°C depending on coating. Their key advantages include superior torque transmission through the hex socket design and compact head profile for space-constrained installations. The primary limitation is the requirement for compatible hex key tools (5mm driver). Widely used in heavy machinery assembly, electrical enclosures, and structural frameworks, these screws provide reliable fastening where flush mounting and high mechanical stability are critical.
