S-90236A171 M8 x 45 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
• High-torque installation capability thanks to the Torx T45 drive, reducing cam-out and tool wear during assembly
• Reliable strength performance with Class 8.8 rating, ensuring consistent load-bearing capacity for demanding applications
• Optimized thread engagement with coarse M8 x 1.25mm threading, providing faster installation and vibration resistance
• Flush mounting design with standard 90° flat head profile, creating smooth surfaces in assembled components
• Precision thread quality with Class 6h fit and full threading, delivering secure fastening across the entire 45mm length
• Enhanced durability with Rockwell C22 hardness, maintaining structural integrity under repeated stress

Professional Applications & Engineering Value

These M8 flat head screws with Torx T45 drive are engineered to solve critical fastening challenges in industrial equipment, machinery assembly, and structural frameworks. The zinc-plated alloy steel construction provides essential corrosion protection where components face moisture or chemical exposure, while the Class 8.8 strength grade ensures reliable performance under dynamic loads and vibration. The coarse metric thread (M8 x 1.25mm) enables rapid installation in various materials without compromising holding power, and the flat head design allows for seamless integration where protruding fasteners are unacceptable. These fully threaded fasteners deliver uniform clamping force across the entire 45mm length, making them ideal for applications requiring consistent thread engagement in thick materials or stacked components.

Specification Summary & Compliance

This fastener meets ISO 14581 specifications for dimensional accuracy and performance standards. The metric coarse thread maintains Class 6h tolerance for precise fit, while the manufacturing process ensures consistent Rockwell C22 hardness throughout. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, these screws are suitable for use in environmentally conscious manufacturing operations and international markets requiring strict material compliance.
