Product Description

The M3x45 hex socket screws, also referred to as Cylindrical head Allen screws, are metric hex drive screws designed for high-precision fastening in mechanical assemblies, automotive components, and industrial equipment. These screws feature an M3 thread diameter, 45mm length, and a cylindrical head with a hex socket requiring a 2.5mm Allen key. Typically made from grade 8.8 steel or stainless steel, they operate in temperature ranges from -20°C to 120°C and withstand vibrations in demanding environments. Their corrosion-resistant coatings, such as zinc or black oxide, enhance durability in outdoor or humid conditions. Advantages include compact installation space, high torque capacity (up to 4.4 Nm for steel variants), and compatibility with automated assembly systems. A limitation is the need for precise socket alignment to avoid tool slippage. Widely used in machinery, robotics, and electronics, these screws excel in applications requiring secure, flush-mounted fasteners with metric standardization.
