S-90910A930 M2.2 x 5 mm ASME B18.3.4M Stainless Steel Button Head Torx Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance thanks to 18-8 Stainless Steel construction, ideal for harsh or washdown environments.
• Enhanced torque transmission and reduced cam-out with the precision Torx T6 drive, ensuring secure fastening and tool longevity.
• Increased durability and surface protection from the passivated finish, which helps prevent galling and extends the screw's service life.
• Reliable holding power from a high 100,000 psi tensile strength and Rockwell B96 hardness, providing consistent performance under load.
• Simplified and faster assembly with a coarse thread pitch and Class 4g6g fit, offering excellent engagement in a wide range of materials.
• Secure, low-profile fastening with the rounded button head design, minimizing protrusion while providing a finished appearance.
• Guaranteed quality and material safety through compliance with ASME B18.3.4M, RoHS 3, and REACH standards.

Professional Applications & Engineering Value

This M2.2 metric screw is engineered for precision applications where reliability is non-negotiable. The combination of 18-8 Stainless Steel and a passivated finish directly addresses the common industrial challenge of fastener failure due to corrosion and chemical exposure, making it a robust choice for electronics, medical devices, and food processing equipment. The Torx T6 drive provides a significant engineering advantage by maximizing torque transfer, which prevents stripping and damage to the drive recess—a critical factor in high-volume assembly lines. Its fully threaded design and coarse thread ensure strong holding power in both metals and plastics, reducing the risk of loosening from vibration. This screw delivers predictable performance and long-term value in demanding industrial fastening scenarios.
