S-90236A125 M3 x 25 mm ISO 14581 Alloy Steel Torx Flat Head Screws

Key Features & Benefits at a Glance

• Exceptional Corrosion Resistance – Zinc-plated alloy steel construction provides reliable protection against rust and environmental degradation in demanding industrial settings.
• Superior Torque Transmission – The T10 Torx drive design minimizes cam-out, allowing for higher torque application and reducing the risk of tool slippage and fastener damage.
• High Mechanical Strength – Class 8.8 strength grade and Rockwell C22 hardness ensure excellent load-bearing capacity and durability under high-stress conditions.
• Optimized for Flush Mounting – The standard flat head with a 90° countersink angle allows the screw to sit flush with the material surface, providing a clean, aerodynamic finish.
• Reliable Thread Engagement – Fully threaded M3 x 0.5 mm coarse spacing with Class 6h fit ensures consistent, secure fastening and vibration resistance in assembled components.
• Broad Industrial Compliance – Meets ISO 14581 for dimensional accuracy and is RoHS 3 & REACH compliant, ensuring safety and environmental responsibility.
• Simplified Inventory & Assembly – Standardized metric right-hand threading streamlines procurement and speeds up installation in high-volume production environments.

Professional Applications & Engineering Value

These M3 flat head screws are precision-engineered to address critical assembly challenges in sectors like electronics, automotive, and machinery manufacturing. The zinc-plated alloy steel offers a robust barrier against corrosion, significantly extending service life in humid or chemically aggressive environments. The Torx T10 drive enhances assembly efficiency by enabling higher torque application without stripping the drive, which is vital for automated production lines and repetitive manual installations. With a Class 8.8 strength grade and fully threaded design, these screws provide uniform clamping force and excellent resistance to loosening under dynamic loads. The 90° countersink and flat head profile ensure a seamless fit, eliminating protrusions that could interfere with moving parts or aesthetic requirements. Ideal for securing panels, chassis, and internal components, these metric screws deliver reliable performance while complying with international ISO 14581 standards for dimensional consistency.
