S-91263A941 M12 x 45 mm DIN 7991 Alloy Steel Hex Drive Flat Head Screws

Key Features & Benefits at a Glance

• Exceptional load-bearing capacity with 120,000 PSI tensile strength for reliable performance in demanding applications
• Superior corrosion resistance provided by zinc-plated alloy steel construction, extending service life in harsh environments
• Precise installation control through 8mm hex drive design that prevents cam-out and ensures proper torque application
• Maximum thread engagement with fully threaded design that delivers superior holding power across the entire fastener length
• Optimized for heavy-duty applications featuring Class 10.9 strength grade and Rockwell C32 hardness for repeated stress resistance
• Quick assembly efficiency with coarse thread spacing (1.75mm pitch) that reduces installation time while maintaining secure fastening
• Regulatory compliance assurance meeting DIN 7991 standards with RoHS 3 and REACH environmental directives

Professional Applications & Engineering Value

Engineered for heavy-duty industrial applications, these M12 flat head screws deliver critical performance where vibration resistance and structural integrity are paramount. The zinc-plated alloy steel construction provides essential corrosion protection for machinery, equipment frames, and structural assemblies exposed to demanding environments. The fully threaded metric design with Class 6g thread fit ensures precise engagement in pre-tapped holes or with matching nuts, while the 90° countersink angle creates a flush surface finish critical for safety and aesthetics. The hex drive configuration allows for high-torque installation without slippage, making these Class 10.9 fasteners ideal for construction, automotive, and manufacturing applications where failure is not an option.

Specification Summary & Compliance

This metric flat head screw features M12 x 1.75mm coarse threading with Class 6g thread tolerance, ensuring precise fit with standard metric components. Manufactured to DIN 7991 specifications with full compliance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental directives. The fastener maintains dimensional accuracy with 45mm length, 24mm head diameter, and standard flat head profile. Mechanical properties include Class 10.9 strength rating with verified 120,000 PSI tensile strength and Rockwell C32 hardness, confirming consistent performance across production batches for engineering-critical applications.
