S-90180A616 M6 x 40 mm ISO 4014, DIN 931 High-Strength Metric Class 10.9 Steel Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 150,000 psi ensures reliable performance in high-stress industrial applications, preventing fastener failure.
• Superior corrosion resistance from blue-dyed zinc plating protects against harsh environments, extending service life and reducing maintenance needs.
• High-strength Class 10.9 rating and Rockwell C32 hardness provide dependable load-bearing capacity and durability under demanding conditions.
• Precise Class 6g thread fit and coarse 1mm pitch enable quick, secure installation with standard tools, minimizing assembly time.
• Partially threaded design with 18mm minimum thread length offers optimal clamping force control for varied material thicknesses.
• External hex drive and 10mm head width allow for easy torque application with common wrenches, enhancing installation efficiency.
• Compliance with ISO 4014/DIN 931 and RoHS 3/REACH ensures global quality standards and environmental safety for regulated industries.

Professional Applications & Engineering Value

Engineered for demanding industrial applications, this M6 hex head screw combines high-strength steel and blue-dyed zinc plating to address critical challenges in machinery assembly, automotive components, and structural frameworks. The Class 10.9 strength grade and Rockwell C32 hardness prevent stripping and shear failure under dynamic loads, while the coarse metric thread with 1mm pitch resists vibration loosening in high-cycle environments. The partially threaded shank allows precise joint compression without over-tightening, making it ideal for securing engine parts, conveyor systems, and heavy-duty equipment where corrosion resistance and ISO 4014 compliance are mandatory for operational safety and longevity.

Specification Summary & Compliance

This fastener meets ISO 4014 specifications (equivalent to DIN 931) with M6 x 1mm coarse threads and Class 6g thread fit tolerance for consistent dimensional accuracy. Manufacturing adheres to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring no restricted substances are used. The 40mm length with 18mm minimum thread engagement and right-hand threading conforms to international metric standards for reliable interoperability in global supply chains.
