S-90236A110 M2.5 x 4 mm ISO 14581 Alloy Steel Torx Flat Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc plating, extending service life in demanding industrial environments
• High-strength Class 8.8 rating provides reliable load-bearing capacity and resistance to shear forces
• Enhanced torque transmission with T8 Torx drive, reducing cam-out risk and tool wear during installation
• Secure fastening in thin materials through fully threaded M2.5 coarse thread design with Class 6h fit
• Flush mounting capability with 90° countersink flat head, ideal for applications requiring smooth surfaces
• Consistent performance ensured by Rockwell C22 hardness and ISO 14581 manufacturing standards
• Environmental compliance meeting RoHS 3 and REACH regulations for global supply chain integration

Professional Applications & Engineering Value

These M2.5 flat head screws deliver critical engineering solutions where space constraints and material thickness pose challenges. The zinc-plated alloy steel construction prevents galvanic corrosion in electronic enclosures and machinery assemblies, while the Torx T8 drive enables high-torque installation without damaging the screw head - particularly valuable in automated production lines. The fully threaded coarse pitch design ensures maximum grip in sheet metal, plastics, and composite materials, preventing loosening under vibration. With 4mm length and 90° countersink, these fasteners provide reliable flush mounting in precision equipment, automotive components, and industrial controls where protrusions are unacceptable.
