• Comprehensive regulatory compliance including RoHS 3 and REACH ensures environmental and safety standards are met

Professional Applications & Engineering Value

This M12 hex head screw delivers critical engineering advantages through its 18-8 stainless steel composition and metric coarse pitch threading. The material's inherent corrosion resistance makes it ideal for applications exposed to moisture, chemicals, or outdoor elements, reducing maintenance frequency and replacement costs. The fully threaded design along the entire 120 mm length ensures maximum grip range and uniform clamping force distribution, preventing joint loosening under vibration. With its external hex drive and standardized 19 mm head, it enables efficient installation in confined spaces using common industrial tools. These characteristics make it particularly valuable in structural assemblies, machinery manufacturing, and infrastructure projects where high tensile strength and long-term reliability are paramount.

Specification Summary & Compliance
