Details
Product Overview
Mining nuts are high-strength fasteners specifically designed for heavy-load bolted connections in mining, tunneling, and other demanding industrial applications. Also known as high-strength hex nuts, bolting nuts, or threaded nuts for rock bolts, these products ensure reliable mechanical performance, excellent fatigue resistance, and long-term durability.
Our mining nuts are manufactured for precise dimensions, reliable performance, and compatibility with standard rock bolts, threaded rods, and support systems.
