Product Description

The M4x90 hex socket screws, also known as DIN 912 M4x90 screws, are precision-engineered Cylinder head hex screws M4 designed for robust fastening applications. Featuring a cylindrical head with an internal hex socket, these screws require a 4mm hex key for installation and comply with DIN 912/ISO 4762 standards. Constructed from high-tensile steel or stainless steel (A2/A4), they offer corrosion resistance and durability with surface treatments like black oxide or zinc plating. Operating within a temperature range of -50°C to 250°C, they are ideal for high-vibration environments in automotive, machinery, and industrial automation sectors. Key advantages include precise torque transmission (3-5 Nm recommended) and compact head design for space-constrained assemblies, though their 90mm length may limit use in ultra-compact spaces. Widely used for securing structural components, engine parts, and electrical enclosures.
