Professional Applications & Engineering Value

These M2 socket head cap screws deliver exceptional engineering value through their Class 12.9 high-strength rating and zinc-plated alloy steel construction, specifically designed to address common industrial fastening challenges. The coarse thread pitch of 0.4mm combined with Class 5g6g thread fit provides superior vibration resistance and prevents loosening in dynamic applications such as machinery, automotive assemblies, and precision equipment. The fully threaded design ensures maximum grip length in thin materials and confined spaces, while the standard hex drive system facilitates quick installation and removal with standard industrial tools. These metric socket screws are engineered to maintain clamping force integrity in high-vibration environments, making them ideal for critical applications where fastener reliability directly impacts operational safety and equipment longevity.

Specification Summary & Compliance

This M2 x 0.4mm socket head cap screw features precision Class 5g6g thread tolerance according to metric standards, with a coarse thread spacing suitable for general industrial applications.
