S-97050A203 M20 x 45 mm DIN 6912 Alloy Steel Low-Profile Socket Head Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with black-oxide coating for longer service life in demanding industrial environments
• Superior strength-to-weight ratio from Class 8.8 alloy steel construction, supporting heavy-duty applications with 110,000 psi tensile strength
• Precise installation and reduced cam-out through 17mm hex drive with pilot recess design for secure tool engagement
• Space-saving low-profile head (30mm diameter, 12mm height) ideal for confined spaces while maintaining high torque capability
• Reliable thread engagement with Class 6g thread fit and M20x2.5 coarse thread pattern for quick assembly and vibration resistance
• Optimized load distribution through partially threaded design, concentrating strength where needed most
• Industry-standard compliance meeting DIN 6912 specifications for consistent performance and interchangeability

Professional Applications & Engineering Value

These metric socket head cap screws deliver critical performance advantages for industrial machinery, automotive assemblies, and heavy equipment manufacturing. The black-oxide alloy steel construction provides essential corrosion protection while maintaining the Class 8.8 strength rating required for high-stress applications. The low-profile socket head with 17mm hex drive and pilot recess ensures positive tool engagement, preventing stripping during high-torque installation. The partially threaded design with M20 coarse threads (2.5mm pitch) offers optimal clamping force distribution while the Class 6g thread fit guarantees precise mating with corresponding nuts and tapped holes. This combination addresses common industrial challenges including space constraints, vibration loosening, and corrosion-induced failure.

Specification Summary & Compliance

Manufactured to exact DIN 6912 standards with Class 6g thread tolerance ensuring dimensional accuracy and interchangeability. The metric coarse thread (M20x2.5) provides reliable engagement while the 45mm length with 26mm minimum thread length offers versatile fastening solutions. Full compliance with RoHS 3 (2015/863/EU) regulations guarantees environmental safety and restricted substance control. Mechanical properties include Rockwell C20 hardness and 110,000 psi tensile strength certified to Class 8.8 specifications for consistent performance in critical applications.
