Professional Applications & Engineering Value

Engineered for heavy-duty industrial applications, these M20 hex head screws deliver critical performance where structural integrity matters most. The hot-dipped galvanized steel construction provides exceptional corrosion protection for outdoor infrastructure, construction frameworks, and machinery exposed to environmental elements. The Class 10.9 strength rating combined with 150,000 psi tensile strength ensures reliable performance in high-stress connections, while the partially threaded design concentrates thread engagement where needed most, preventing joint slippage in structural steel connections. The metric coarse threading (M20x2.5) facilitates quick assembly in field applications, reducing installation time while maintaining the precision required for DIN 6914/ISO 7412 compliant engineering projects across construction, heavy equipment, and industrial manufacturing sectors.
