S-90074A125 M12 x 40 mm Serrated-Flange Socket Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-oxide coating, extending service life in harsh industrial environments
• Exceptional tensile strength of 140,000 psi provides reliable fastening under high-stress conditions
• Enhanced vibration resistance through serrated locking flange design, preventing loosening in dynamic applications
• Precise Class 5g6g thread fit ensures smooth installation and consistent clamping force
• Optimized drive engagement with 10mm hex socket for maximum torque transmission and reduced tool wear
• Rockwell C39 hardness maintains thread integrity and prevents stripping during repeated use
• Full-threaded M12 design allows for adjustable engagement depth across various material thicknesses

Professional Applications & Engineering Value

These flanged socket head cap screws solve critical fastening challenges in heavy machinery, automation systems, and structural assemblies. The black-oxide alloy steel construction provides superior protection against rust and chemical exposure, while the serrated locking flange eliminates the need for separate washers and prevents rotational slippage under vibration. With M12 coarse thread and 1.75mm pitch, installation is faster and more reliable in steel frameworks and equipment mounting. The fully threaded design ensures maximum thread engagement in both thick and thin materials, making these metric fasteners ideal for adjustable fixtures and precision alignment applications across manufacturing and engineering sectors.

Specification Summary & Compliance

Manufactured to precise metric dimensions with Class 5g6g thread tolerance ensuring consistent fit and performance. Complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Features fully threaded M12x1.75mm coarse thread configuration with 40mm length and 22.5mm flange diameter for optimal load distribution.
