Product Overview
Metric Grade 10.9 threaded rods are high-strength carbon steel fasteners manufactured to ISO 898-1 and EN 14399 standards. These rods are fully threaded along their length and are designed for use in structural bolting, machinery assembly, and heavy-duty anchoring where high tensile strength and reliable preload are critical. Grade 10.9 indicates a minimum tensile strength of 1040 MPa and a yield strength of 940 MPa, making them suitable for demanding applications in construction, automotive, and engineering sectors.
Metric Grade 10.9 threaded rods are typically supplied in plain, zinc-plated, or hot-dip galvanized finishes for enhanced corrosion resistance. They are widely specified for steel structures, equipment foundations, and flange connections where superior mechanical performance and dimensional accuracy are required.
