• Secure and reliable fastening with Class 5g6g thread fit, providing consistent engagement and vibration resistance in dynamic applications.
• Easy installation and removal using a standard 2 mm hex drive, compatible with common tools for efficient maintenance and assembly.
• Enhanced grip and handling from the knurled head texture, allowing for better manual adjustment in tight spaces.
• Durable and standardized design meeting ISO 7379 specifications, ensuring interchangeability and performance in metric-based systems.
• Environmentally compliant with RoHS 3 and REACH standards, supporting sustainable and safe manufacturing practices.

Professional Applications & Engineering Value

This M2.5x0.45mm shoulder screw is engineered to address common challenges in precision assembly, such as misalignment and component wear. Made from 18-8 stainless steel with a passivated finish, it resists corrosion and extends service life in demanding settings like machinery, electronics, and automotive systems. The 12mm shoulder length with minimal tolerance ensures accurate positioning of parts, reducing stress and improving load distribution. Its hex socket head and coarse metric thread facilitate quick installation, while the knurled texture enhances grip for manual adjustments. Ideal for industrial applications requiring reliable fasteners, this screw supports efficient production and maintenance workflows.
