S-90327A181 M10 x 40 mm DIN 7984 Alloy Steel Low-Profile Socket Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc plating that protects against rust and extends service life in demanding environments
• High tensile strength of 110,000 psi ensures reliable load-bearing capacity and prevents fastener failure under stress
• Class 8.8 strength rating provides consistent performance for medium-duty to heavy-duty industrial applications
• Low-profile socket head design allows for installation in confined spaces while maintaining high torque capability
• Coarse metric thread (M10 x 1.5mm) enables quick assembly and reduces cross-threading risks during installation
• Partially threaded shank offers optimal grip strength when precise clamping force distribution is required
• Compliance with DIN 7984 standard guarantees dimensional accuracy and interchangeability with existing metric fastener systems

Professional Applications & Engineering Value

These Class 8.8 socket head cap screws deliver exceptional engineering value through their zinc-plated alloy steel construction, specifically engineered to address common industrial fastening challenges. The M10 coarse thread configuration with 1.5mm pitch provides superior resistance to vibration loosening while enabling rapid assembly in production environments. The low-profile hex socket head accommodates space-constrained applications in machinery, automotive assemblies, and equipment manufacturing where standard head heights would interfere with operation. With 26mm minimum thread engagement, these partially threaded fasteners ensure optimal stress distribution across joined components, preventing material deformation in critical connections. The combination of Rockwell C20 hardness and controlled zinc plating creates a durable fastener solution that withstands both mechanical stresses and environmental exposure in manufacturing, construction, and heavy equipment applications.

Specification Summary & Compliance

This socket head cap screw maintains precise Class 6g thread fit tolerance according to metric standards, ensuring consistent engagement and reliable performance. Manufacturing complies with DIN 7984 specifications for dimensional accuracy and mechanical properties. The product meets RoHS 3 (2015/863/EU) compliance for restricted substances and REACH (EC 1907/2006) regulations regarding chemical safety. With 40mm total length and 7mm hex drive compatibility, these fasteners provide standardized installation using common industrial tools while maintaining full regulatory compliance for global industrial applications.
