S-90180A634 M10 x 40 mm ISO 4014, DIN 931 High-Strength Metric Class 10.9 Steel Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional load-bearing capacity with 150,000 psi tensile strength and Class 10.9 rating for reliable performance in high-stress applications.
• Superior corrosion resistance thanks to the blue-dyed zinc plating, extending service life in harsh industrial environments.
• Optimized thread engagement with a partially threaded design and Class 6g fit for precise, secure fastening and reduced risk of cross-threading.
• High durability and wear resistance from Rockwell C32 hardness, ensuring consistent performance under repeated use.
• Efficient installation and removal with an external hex drive and 17mm head width, compatible with standard tools for quick assembly.
• Wide industrial compatibility due to metric coarse threading (M10 x 1.5mm) and compliance with ISO 4014 DIN 931 standards.
• Environmental and safety compliance with RoHS 3 and REACH regulations, making them suitable for global supply chains.

Professional Applications & Engineering Value

These M10 hex head screws are engineered to address critical challenges in industrial settings, such as vibration-induced loosening and corrosion in demanding environments. Made from high-strength Class 10.9 steel, they provide reliable clamping force for machinery, structural assemblies, and automotive components. The blue-dyed zinc-plated finish enhances corrosion resistance, reducing maintenance needs in exposed or humid conditions. With a partially threaded design and coarse thread spacing, they offer faster installation and improved grip in softer materials or where alignment is critical. The external hex drive ensures easy torque application with common tools, minimizing assembly time and errors in high-volume production lines.

Specification Summary & Compliance
