• Reliable coarse threading (M20 x 2.5mm) enables faster assembly and reduced risk of cross-threading.
• Precision Class 6g thread fit guarantees consistent, secure fastening with excellent vibration resistance.
• Partially threaded design offers optimal clamping force distribution and prevents joint loosening.
• External hex drive with 30mm head allows for high-torque installation using standard tools.
• Full compliance with international standards including ISO 4014/DIN 931, ensuring interchangeability and quality assurance.

Professional Applications & Engineering Value

This M20 hex head screw delivers critical engineering solutions where corrosion resistance and structural integrity are paramount. The 18-8 stainless steel material prevents rust and chemical degradation in marine, chemical processing, and outdoor installations. Its coarse metric thread (M20 x 2.5mm) maintains holding power in vibrating machinery and structural steel connections, while the partially threaded shank concentrates clamping force precisely where needed. The external hex drive accommodates high installation torque for heavy-duty assemblies, making it ideal for construction equipment, industrial machinery, and infrastructure projects requiring ISO 4014/DIN 931 compliant fasteners.
