S-91210A630 M12 x 20 mm DIN 914, ISO 4027 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with a 90° cone point that bites into surfaces for secure, vibration-resistant fastening in dynamic industrial environments.
• Exceptional durability and wear resistance thanks to the high-strength alloy steel construction and Rockwell C45 hardness, ensuring a long service life.
• Precise and reliable thread engagement with Class 5g6g thread fit and coarse M12x1.75mm thread, enabling quick assembly and consistent performance.
• Easy installation in confined spaces with its headless, hex drive design, allowing for flush mounting and tool access from the side.
• Guaranteed material safety and compliance with RoHS 3 and REACH regulations, making it suitable for use in sensitive and regulated industries.
• Interchangeable and standardized performance as it meets DIN 914 and ISO 4027 specifications, ensuring compatibility and reliability in global applications.

Professional Applications & Engineering Value

This alloy steel set screw is engineered to solve critical challenges in industrial assembly, where components are subject to high stress, vibration, and misalignment. The M12 coarse thread and Class 5g6g thread fit provide excellent tolerance control, reducing the risk of cross-threading and ensuring a secure fit in demanding applications like machinery, automotive systems, and precision equipment. The headless design with a hex drive allows for installation in tight spaces where a protruding head is not feasible, while the 90° cone point creates a firm, self-centering grip that prevents loosening under dynamic loads. Manufactured from high-strength alloy steel and hardened to Rockwell C45, it offers superior resistance to shear and fatigue, making it an ideal choice for permanent or semi-permanent fastening solutions that require maximum reliability and corrosion resistance.
