Professional Applications & Engineering Value

This M12 brass flat head screw is engineered to address common industrial challenges like corrosion, vibration loosening, and assembly inefficiency. The brass material offers inherent resistance to rust and galvanic corrosion, making it suitable for marine, electrical, and plumbing applications where moisture is a concern. With a coarse thread pitch of 1.75mm and Class 6g thread fit, it provides robust holding power in soft materials and reduces cross-threading risks during installation. The fully threaded design and 90° countersink ensure a secure, flush fit in pre-drilled holes, ideal for machinery, automotive components, and furniture where a smooth surface is critical. Compliant with DIN 7991, these screws deliver consistent performance and reliability in industrial fastening systems.
