Product Description

The M6x40 hex socket screw, also known as a cylindrical head hex screw or socket head cap screw M6, is a precision fastener with a 6 mm nominal diameter and 40 mm shank length. Featuring a cylindrical head and internal hexagonal drive (ISO 4762 standard), it requires an Allen key for installation. Typically manufactured from alloy steel (Grade 12.9) or stainless steel (A2/A4), it offers tensile strengths up to 1,200 MPa. Designed for high-torque applications in machinery, automotive assembly, and aerospace equipment, its compact head profile suits space-constrained environments. Operational temperature ranges from -50°C to +150°C for steel variants. Key advantages include vibration resistance and reliable clamping force, though proper drive tool alignment is critical to prevent head stripping. Common applications include securing heavy-duty components in industrial automation systems and engine assemblies.
