S-92125A631 M20 x 80 mm DIN 7991, ISO 10642 Stainless Steel Hex Drive Flat Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel and passivated finish for longevity in harsh environments
• High tensile strength of 70,000 PSI ensures reliable performance under heavy loads and vibration
• Hex drive design with 12mm drive size provides secure tool engagement and prevents stripping during installation
• Standard 90° countersink angle and flat head profile allows for flush mounting in pre-drilled holes
• Coarse M20 x 2.5mm thread with Class 6g fit enables quick assembly and secure fastening in various materials
• Partially threaded shank with 46mm minimum thread length optimizes grip range while reducing weight
• Full compliance with DIN 7991/ISO 10642 standards guarantees dimensional accuracy and interchangeability

Professional Applications & Engineering Value

This M20 metric flat head screw delivers critical engineering solutions where flush surface mounting and high-strength fastening are required. The 18-8 stainless steel construction combined with a passivated finish provides exceptional resistance to oxidation and chemical exposure, making it ideal for machinery, structural assemblies, and outdoor equipment. The hex drive design ensures maximum torque transmission without cam-out, while the coarse thread pitch and Class 6g thread fit facilitate rapid installation in steel, aluminum, and composite materials. Its partially threaded configuration concentrates clamping force precisely where needed, preventing joint loosening in high-vibration industrial environments.

Specification Summary & Compliance
