S-93070A107 M4 x 20 mm DIN 7984 Alloy Steel Low-Profile Socket Head Screws

Key Features & Benefits at a Glance

• Superior load-bearing capability with Class 8.8 strength rating and 110,000 psi tensile strength for reliable performance in demanding applications
• Enhanced corrosion resistance and durability through high-quality alloy steel construction with Rockwell C20 hardness
• Space-saving installation with low profile socket head design requiring minimal clearance while maintaining 7mm head diameter
• Secure, slip-resistant fastening enabled by 2.5mm hex drive that prevents tool slippage during installation
• Precise thread engagement with Class 6g thread fit and metric coarse thread (M4 x 0.7mm) ensuring consistent clamping force
• Full-length thread coverage across the 20mm length provides maximum grip and adjustment flexibility
• Regulatory compliance assurance meeting DIN 7984 specifications and environmental standards including RoHS 3 and REACH

Professional Applications & Engineering Value

These low profile socket head cap screws deliver exceptional engineering value in space-constrained industrial applications where reliability is paramount. The Class 8.8 alloy steel construction provides outstanding strength-to-weight ratio, making them ideal for machinery, automotive assemblies, and precision equipment requiring high tensile strength (110,000 psi) without excessive bulk. The metric coarse threading (M4 x 0.7mm) with Class 6g thread fit ensures rapid installation and vibration resistance, while the 2.5mm hex drive in the low profile socket head allows for tight installations where standard socket heads cannot fit. Fully compliant with DIN 7984 standards, these fully threaded fasteners provide consistent performance across their entire 20mm length, solving common challenges of strip-out and insufficient thread engagement in critical assemblies.

Specification Summary & Compliance

This M4 socket head cap screw features precise Class 6g thread fit per ISO metric standards with coarse thread spacing (0.7mm pitch). Manufacturing conforms to DIN 7984 specifications for dimensional accuracy and performance requirements. The fastener is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and workplace safety. With right-hand thread direction and fully threaded rod design, these screws maintain consistent mechanical properties throughout their 20mm length while meeting international quality standards for industrial fastener applications.
