Professional Applications & Engineering Value

Engineered for demanding industrial applications, these M22 hex head screws deliver critical performance where structural integrity matters most. The hot-dipped galvanized steel construction provides superior protection against corrosion in outdoor installations, chemical processing plants, and marine environments. The Class 10.9 strength rating combined with 150,000 psi tensile strength ensures reliable performance in heavy machinery, structural steel connections, and equipment requiring high-strength fastening. The metric coarse thread (M22x2.5) with partial threading allows for optimal stress distribution across the 56mm grip length, preventing joint failure in vibration-prone applications. These hex head fasteners are specifically designed to meet the rigorous demands of construction, manufacturing, and infrastructure projects where DIN 6914/ISO 7412 compliance is mandatory.
