Professional Applications & Engineering Value
Engineered for industrial machinery assembly and heavy equipment manufacturing, these M20 socket head cap screws deliver critical performance advantages. The black-oxide alloy steel construction provides exceptional corrosion protection in harsh operating conditions, while the Class 8.8 strength rating ensures reliable fastening in high-vibration applications. The low-profile socket head design with 17mm hex drive enables efficient installation in space-constrained assemblies. The partially threaded configuration with M20x2.5 coarse thread offers optimal clamping force distribution, making these metric socket screws ideal for structural connections requiring precise preload control and long-term durability in automotive, construction, and manufacturing applications.
Specification Summary & Compliance
Manufactured to DIN 6912 standards with Class 6g thread fit tolerance for precision engagement. Features M20x2.5 coarse thread with 26mm minimum thread length and 40mm overall length. Compliant with RoHS 3 (2015/863/EU) environmental regulations. The Rockwell C20 hardness rating ensures consistent mechanical properties throughout the fastener's service life.
