Product Description

The M4x85 hex socket cap screw, compliant with DIN 912 M4 cylinder screw standards, features a cylindrical head design with internal hex drive (ISO 4762). This M4-85 cylindrical hex head bolt measures 85mm in length with a 4mm thread diameter and 0.7mm pitch. Typically crafted in steel grade 10.9 (tensile strength 1000 MPa) or stainless steel A2-70, it operates within -50°C to +120°C environments. The hexagonal socket (Allen key) requires a 3mm hex tool for installation, with torque ratings up to 4.4Nm for steel variants. Widely used in machinery assembly, automotive engineering, and industrial equipment for high-strength fastening, its advantages include low-profile head clearance, corrosion resistance, and vibration resistance, though precise alignment is required during installation. Surface treatments like zinc plating or black oxide enhance durability in harsh conditions.
