S-90236A121 M3 x 10 mm ISO 14581 Alloy Steel Torx Flat Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc plating that protects against rust and extends service life in harsh industrial environments
• High-strength Class 8.8 rating ensures reliable performance under heavy loads and vibration, reducing fastener failure risks
• Enhanced torque transmission from the T10 Torx drive minimizes cam-out and tool slippage for secure, efficient installations
• Flush, low-profile mounting with a 90° countersink angle and flat head design for smooth surfaces and improved aesthetics
• Precise Class 6h thread fit provides consistent engagement and reduces cross-threading in metric coarse thread applications
• Exceptional durability from Rockwell C22 hardness, maintaining structural integrity in high-stress assemblies
• Full threading along the 10 mm length offers maximum grip and adjustability across the entire fastener

Professional Applications & Engineering Value

Engineered for demanding industrial settings, these M3 flat head screws deliver critical advantages in machinery, electronics, and automotive assemblies. The zinc-plated alloy steel construction resists environmental degradation, while the Torx T10 drive ensures high torque application without stripping—solving common installation challenges. With a coarse 0.5 mm pitch and Class 6h thread fit, these metric fasteners provide rapid assembly and secure holding power, minimizing loosening in vibrating equipment. The fully threaded design and 90° countersink enable seamless integration into tight spaces, offering engineers a reliable solution for flush-mount applications that require both strength and precision.
