S-91294A016 M2.5 x 8 mm Alloy Steel Hex Drive Flat Head Screws

Key Features & Benefits at a Glance

• Exceptional strength and reliability with Class 10.9 rating and 120,000 psi tensile strength, ensuring secure fastening in high-stress industrial environments.
• Superior corrosion resistance thanks to the Black-Oxide finish on Alloy Steel, prolonging service life in harsh or outdoor applications.
• Precise and easy installation with a 1.5 mm hex drive and standard flat head profile, reducing tool slippage and assembly time.
• Optimized thread engagement through fully threaded M2.5 coarse pitch (0.45 mm) design, providing strong hold and vibration resistance.
• Consistent dimensional accuracy with Class 6g thread fit, ensuring reliable performance and interchangeability in metric assemblies.
• Enhanced durability from Rockwell C32 hardness, maintaining integrity under repeated loads and mechanical stress.
• Broad regulatory compliance including RoHS 3 and REACH, making them suitable for global markets and sensitive applications.

Professional Applications & Engineering Value

Engineered for demanding industrial settings, these M2.5 flat head screws deliver critical performance where precision and strength are non-negotiable. The Black-Oxide Alloy Steel construction combats corrosion, reducing maintenance in automotive, machinery, and electronic enclosures exposed to moisture or chemicals. With a 90° countersink angle and hex drive, they sit flush for aerodynamic or safety-critical surfaces, while the fully threaded coarse pitch ensures rapid installation and high clamp force. Ideal for securing components in tight spaces, these metric screws prevent loosening under vibration, enhancing the longevity of assemblies in manufacturing, robotics, and heavy equipment.

Specification Summary & Compliance
