S-90258A109 M2.5 x 8 mm DIN 966, ISO 7047 Stainless Steel Phillips Oval Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance thanks to 18-8 stainless steel construction and passivated finish, ensuring long-term reliability in harsh environments.
• Excellent drive engagement and reduced cam-out with the Phillips drive style, allowing for efficient installation and reduced tool slippage.
• High tensile strength of 70,000 psi provides reliable clamping force and resistance to mechanical loads in demanding applications.
• Coarse thread pitch (0.45mm) enables faster installation and better performance in materials where fine threads might strip.
• Precise Class 6g thread fit ensures consistent, reliable mating with nuts and tapped holes, reducing assembly issues.
• Fully threaded design offers maximum grip and holding power along the entire length of the screw.
• Compliance with DIN 966 and ISO 7047 standards guarantees dimensional accuracy and interchangeability for global engineering projects.

Professional Applications & Engineering Value

This M2.5 flat head screw is engineered to address common industrial challenges such as component loosening under vibration and corrosion in humid or chemical-laden environments. The 18-8 stainless steel material, combined with a passivated finish, significantly enhances its resistance to oxidation and chemical attack, making it ideal for electronics enclosures, automotive assemblies, and machinery where long-term durability is critical. The Phillips drive and coarse metric thread facilitate quick and secure fastening in softer materials or pre-tapped holes, reducing installation time and improving production line efficiency. Its oval head profile provides a flush finish when seated, minimizing protrusion and ensuring a clean, professional appearance in finished products.
