Key Features & Benefits at a Glance
- Enhanced corrosion resistance with black-oxide coating for extended service life in demanding industrial environments.
- Superior clamping force and reliability from Class 8.8 strength rating and 110,000 psi tensile strength.
- Optimized for high-strength applications with a Rockwell C20 hardness, providing excellent wear resistance.
- Secure, low-profile installation with a hex socket and pilot recess design that minimizes head protrusion.
- Simplified assembly and reduced risk of cross-threading due to coarse M20x2.5 metric threads with Class 6g fit.
- Versatile partial threading allowing for precise grip length control in varied material thicknesses.
- Guaranteed dimensional and performance consistency through compliance with the rigorous DIN 6912 standard.
Professional Applications & Engineering Value
This M20 socket head cap screw is engineered to address critical challenges in heavy machinery, automotive, and structural assemblies where vibration resistance and high tensile loads are paramount. The black-oxide alloy steel construction combats rust and galling, prolonging fastener integrity in harsh conditions. Its low-profile socket head with a hex and pilot recess drive ensures a flush fit and superior torque transmission, reducing the risk of stripping during high-torque applications. The coarse metric thread (M20x2.5) and partial threading enable rapid installation and reliable engagement in both soft and hard materials, making it an ideal industrial fastener for frames, presses, and equipment requiring repeated disassembly without performance degradation.
Specification Summary & Compliance
This screw adheres to precise dimensional tolerances, including a Class 6g thread fit per ISO metric standards, ensuring consistent engagement. It is manufactured in accordance with DIN 6912 for dimensional and mechanical properties, and is fully RoHS 3 (2015/863/EU) compliant, confirming the absence of restricted hazardous substances for safe use in regulated markets.
