S-91294A216 M5 x 25 mm DIN 7991, ISO 10642 Alloy Steel Hex Drive Flat Head Screws

Key Features & Benefits at a Glance

• Exceptional durability with Class 10.9 tensile strength (120,000 psi) for reliable performance in high-stress applications
• Superior corrosion resistance from the black-oxide coating, extending service life in harsh industrial environments
• Precise countersinking with 90° flat head profile ensuring flush mounting and clean aesthetic finish
• Optimized thread engagement through Class 6g thread fit and coarse threading for faster assembly and vibration resistance
• Secure installation enabled by 3mm hex drive design preventing cam-out during high-torque applications
• Full thread coverage along the 25mm length providing maximum grip strength and load distribution
• Regulatory compliance meeting international standards including DIN 7991/ISO 10642, RoHS 3, and REACH

Professional Applications & Engineering Value

These M5 flat head screws deliver critical engineering solutions for industrial applications where high tensile strength and corrosion resistance are paramount. The black-oxide alloy steel construction combined with Class 10.9 strength rating (120,000 psi tensile strength) ensures reliable performance in heavy machinery, automotive assemblies, and structural frameworks subject to dynamic loads and environmental exposure. The fully threaded design with coarse metric threading (0.8mm pitch) enables rapid installation while maintaining vibration resistance, crucial for equipment subjected to continuous operation. The 90° countersink angle and standard flat head profile provide seamless flush mounting in precision applications, eliminating protrusions that could interfere with moving components or compromise safety. These industrial screws are engineered to address common fastening challenges including joint integrity, corrosion prevention, and assembly efficiency.
