S-90236A161 M6 x 40 mm ISO 14581 Alloy Steel Torx Flat Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated alloy steel construction, extending service life in harsh industrial environments
• Exceptional mechanical strength with Class 8.8 rating, providing reliable performance under high-stress applications
• Enhanced torque transmission through T30 Torx drive system, minimizing cam-out and tool slippage during installation
• Optimized thread engagement with Class 6h thread fit and coarse 1mm pitch, ensuring secure fastening and vibration resistance
• Flush mounting capability with standard 90° flat head profile, creating smooth surfaces in assembled components
• Full-length threading for maximum grip along the entire 40mm length, distributing load evenly across fastened materials
• Industry-standard compliance meeting ISO 14581 specifications for dimensional accuracy and performance reliability

Professional Applications & Engineering Value

These M6 flat head screws deliver critical engineering solutions where vibration resistance and flush surface requirements are paramount. The zinc-plated alloy steel construction provides essential corrosion protection for machinery, automotive assemblies, and outdoor equipment exposed to environmental elements. With Rockwell C22 hardness and Class 8.8 strength grade, these fasteners maintain structural integrity under dynamic loads and thermal cycling. The T30 Torx drive system enables higher torque application than traditional drives, reducing installation time and preventing fastener damage in high-volume production environments. The fully threaded design with coarse 1mm pitch ensures rapid assembly and superior pull-out resistance in metals, plastics, and composite materials.

Specification Summary & Compliance

Manufactured to precise ISO 14581 standards with Class 6h thread fit tolerance for consistent dimensional accuracy. The metric coarse thread (M6 x 1mm) with right-hand direction follows international threading specifications. These screws are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global markets. The 40mm length and 11.3mm head diameter maintain standardized proportions for interchangeable use in industrial fastening systems.
