S-90327A201 M12 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 performance under heavy loads and vibration, reducing failure risks
• Low-profile socket head design allows for installation in tight spaces while maintaining high torque capability
• Class 8.8 strength rating provides consistent mechanical properties for critical industrial applications
• Partially threaded shank offers optimal grip and alignment, minimizing stress concentration on threaded sections
• Precision Class 6g thread fit ensures smooth assembly and secure fastening with standard metric components
• Compliance with DIN 7984 guarantees dimensional accuracy and interchangeability in European machinery designs

Professional Applications & Engineering Value

Engineered for heavy-duty industrial applications, these M12 socket head cap screws solve critical fastening challenges where space constraints and high stress coexist. The zinc-plated alloy steel construction provides essential corrosion protection in manufacturing, automotive, and machinery assembly environments, while the low-profile hex drive enables efficient installation with standard 8mm drive tools. With coarse 1.75mm pitch threads and Class 8.8 strength, these metric fasteners deliver reliable clamping force in vibrating equipment, preventing loosening and maintaining structural integrity. The partially threaded design concentrates engagement where needed most, reducing thread damage during repeated disassembly in maintenance operations.

Specification Summary & Compliance

This socket head cap screw features M12 x 1.75mm coarse threads with Class 6g tolerance per ISO metric standards, ensuring precise fit with mating components. Manufacturing conforms to DIN 7984 specifications for dimensional accuracy and mechanical properties. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, containing no restricted substances above threshold limits.
