Product Description

The M3*6 hex socket screws, also known as Cylindrical head M3 screws or Allen screws M3*6, are precision-engineered fasteners designed for high-torque applications. These cylindrical head screws feature a 3mm diameter and 6mm length with a hexagonal socket drive, requiring a corresponding Allen key for installation. Made from hardened steel or stainless steel, they offer corrosion resistance and operate effectively within a temperature range of -40°C to +120°C, making them ideal for machinery, automotive, and electronics industries. The compact cylindrical head design reduces protrusion in tight spaces, while the hex socket ensures secure torque transmission. However, their small size requires precise alignment and compatible tools. These screws are commonly used in precision assembly, equipment frames, and compact devices requiring reliable, low-profile fastening solutions.
