Choosing between 8.8 vs 10.9 bolts requires more than comparing tensile strength. This guide explains how metric bolt property classes work and compares their yield strength, materials, heat treatment, hardness, shear performance, torque requirements, and common applications. Class 8.8 provides a practical balance of strength, ductility, and cost for general structural and mechanical use, while Class 10.9 suits higher-stress and dynamic loads. It also covers SAE equivalents, hydrogen embrittlement, mating hardware, coating selection, supplier verification, and procurement considerations for reliable fastener selection.
Choosing the correct Tek screw sizes requires understanding drill point capacity, screw gauge, thread pitch, length, and material thickness. This guide compares Tek 1, Tek 2, Tek 3, Tek 4, and Tek 5 points to explain where each type performs best, from thin sheet metal to heavy structural steel. It also covers grip range, flute clearance, head styles, load requirements, corrosion resistance, and common installation mistakes. By matching the Tek point and screw dimensions to the application, contractors and engineers can prevent drilling failures, thread binding, damaged fasteners, and weak connections.
