S-94331A105 M3 x 12 mm Stainless Steel Torx Flat Head Screws

Key Features & Benefits at a Glance

• Exceptional corrosion and heat resistance from A286 Stainless Steel, ensuring long-term reliability in demanding environments.
• Superior strength and durability with a 130,000 psi tensile strength and Rockwell C24 hardness, preventing stripping and failure under high stress.
• Secure, cam-out resistant fastening provided by the T8 Torx drive, allowing for higher torque application and reduced tool slippage.
• Precise and reliable thread engagement with a Class 6g fit and coarse M3 x 0.5mm thread, ensuring consistent performance and easy assembly.
• Flush, low-profile installation thanks to the standard flat head with a 90° countersink angle, ideal for applications where a smooth surface is critical.
• Full-length threading (12mm) for maximum grip and holding power across the entire fastener length.
• Compliance with major environmental regulations including RoHS 3 and REACH, making them suitable for global industrial supply chains.

Professional Applications & Engineering Value

This M3 flat head screw, machined from premium A286 Stainless Steel, is engineered to solve critical challenges in high-stress and corrosive environments. Its high tensile strength and Rockwell C24 hardness provide exceptional resistance to vibration loosening and mechanical fatigue, making it ideal for aerospace, automotive, and heavy machinery applications. The T8 Torx drive offers superior torque transfer compared to traditional drives, minimizing the risk of head damage during installation in confined spaces. The fully threaded design with a Class 6g metric coarse thread ensures a secure and precise fit, reducing the likelihood of cross-threading and streamlining assembly line efficiency. The 90° countersink angle allows the screw to sit flush with the material surface, providing a clean finish and preventing snagging in dynamic components.

Specification Summary & Compliance
