S-93700A227 M12 x 30 mm 12-Point Screws

Key Features & Benefits at a Glance

• Exceptional durability with black-oxide alloy steel construction providing corrosion resistance and extended service life in harsh environments.
• Superior load-bearing capacity thanks to 180,000 psi tensile strength and Rockwell C38 hardness, ensuring reliable performance under high stress.
• Enhanced torque application with the external 12-point drive and 14mm drive size, allowing for secure tightening with standard tools.
• Stable fastening and vibration resistance from the integrated flange design, which distributes pressure evenly and reduces loosening.
• Precise and reliable threading with Class 4h thread fit and coarse 1.75mm pitch, enabling quick installation and strong hold in various materials.
• Versatile right-hand metric threading for compatibility with standard industrial components and ease of assembly.
• Full threading along the 30mm length ensures consistent grip and adjustability across the entire fastener.

Professional Applications & Engineering Value

Engineered for demanding industrial settings, this M12 12-point screw addresses common challenges like vibration-induced loosening and high-torque requirements. The black-oxide alloy steel material offers enhanced corrosion resistance, making it ideal for automotive, machinery, and construction applications where exposure to moisture and chemicals is a concern. With a coarse thread pitch of 1.75mm and Class 4h thread fit, it provides rapid assembly and robust clamping force, reducing installation time while maintaining integrity under dynamic loads. The external 12-point drive and flange design work together to prevent slipping during torque application and minimize the need for additional washers, streamlining the fastening process in heavy-duty equipment and structural assemblies.
