S-97050A292 M20 x 40 mm DIN 6912 Alloy Steel Low-Profile Socket Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated alloy steel construction for extended service life in demanding environments
• High tensile strength of 110,000 psi and Class 8.8 rating ensures reliable performance under heavy loads and vibration
• Low-profile socket head design provides a flush finish in space-constrained applications while maintaining structural integrity
• Hex drive with pilot recess offers secure tool engagement and prevents cam-out during high-torque installation
• Partially threaded shank allows for precise clamping force distribution and improved joint stability
• Precision metric coarse threading (M20 x 2.5mm) enables quick assembly and disassembly while maintaining secure fastening
• Full compliance with DIN 6912 standards guarantees dimensional accuracy and interchangeability in industrial applications

Professional Applications & Engineering Value

This M20 socket head cap screw delivers exceptional engineering value through its zinc-plated alloy steel construction and Class 8.8 strength rating. The combination of 110,000 psi tensile strength and Rockwell C20 hardness ensures reliable performance in heavy-duty industrial applications where vibration resistance and load-bearing capacity are critical. The low-profile socket head with 17mm hex drive and pilot recess prevents stripping during high-torque installation, while the partially threaded design provides optimal stress distribution across fastened components. These metric coarse thread fasteners are particularly valuable in machinery assembly, structural frameworks, and equipment manufacturing where DIN 6912 compliance ensures precise fit and long-term reliability in demanding operating conditions.

Specification Summary & Compliance

This socket head cap screw features M20 x 2.5mm metric coarse threading with Class 6g thread fit tolerance, ensuring precise engagement and reliable fastening performance. The 40mm length includes 26mm minimum thread length on the partially threaded shank. Manufacturing and dimensional specifications strictly adhere to DIN 6912 standards, while environmental compliance meets RoHS 3 (2015/863/EU) requirements for restricted substances. The combination of Class 8.8 strength rating, zinc-plated surface treatment, and standardized dimensions guarantees consistent performance and regulatory compliance across industrial applications.
