S-97050A168 M12 x 20 mm DIN 6912 Alloy Steel Low-Profile Socket Head Screws

Key Features & Benefits at a Glance

• Enhanced Durability and Corrosion Resistance: Black-oxide coating on alloy steel provides superior protection against rust and wear, extending service life in harsh industrial environments.
• High Tensile Strength for Demanding Applications: Class 8.8 rating with 110,000 psi tensile strength ensures reliable performance under heavy loads and high-stress conditions.
• Secure and Efficient Installation: 10 mm hex drive with pilot recess offers excellent torque transmission and prevents cam-out, reducing installation time and tool wear.
• Space-Saving Low Profile Design: Reduced head height allows for use in confined spaces without compromising on strength or fastening security.
• Precision Thread Fit for Vibration Resistance: Class 6g thread tolerance and coarse 1.75 mm pitch provide secure engagement and reduced loosening in dynamic applications.
• Consistent Quality and Compliance: Manufactured to DIN 6912 standards and RoHS 3 compliant, ensuring material consistency and environmental safety.
• Optimized for Partial Thread Applications: Partially threaded design allows for precise clamping force control in assemblies requiring unthreaded shank sections.

Professional Applications & Engineering Value

This M12 low profile socket head cap screw delivers exceptional engineering value in applications where space constraints and high mechanical stress coexist. The black-oxide alloy steel construction combined with Class 8.8 strength provides reliable performance in heavy machinery, automotive assemblies, and industrial equipment subjected to vibration and dynamic loads. The hex drive with pilot recess ensures precise alignment and secure fastening, reducing the risk of stripping and improving assembly efficiency. With its coarse thread pitch and Class 6g thread fit, it offers excellent resistance to loosening, making it ideal for high-vibration environments like motors, pumps, and structural frameworks. The low profile head is particularly beneficial in compact designs where clearance is limited, without sacrificing the 110,000 psi tensile strength needed for critical connections.
